Business challenges
Digital transformation is profoundly altering every aspect of how today’s businesses operate and compete. The sheer volume of data that enterprises create, manipulate, and store is growing, and drives a greater need for data governance. In addition, computing environments are more complex than they once were, routinely spanning the public cloud, the enterprise data center, and numerous edge devices ranging from Internet of Things (IoT) sensors to robots and remote servers. This complexity creates an expanded attack surface that’s more challenging to monitor and secure.
At the same time, consumer awareness of the importance of data privacy is on the rise. Fueled by increasing public demand for data protection initiatives, multiple new privacy regulations have recently been enacted, including Europe’s General Data Protection Regulation (GDPR), Insurance Portability and Accountability Act (HIPAA) and other regulatory compliances.
The business value of data has never been greater than it is today. The loss of trade secrets or intellectual property (IP) can impact future innovations and profitability. So, trustworthiness is increasingly important to consumers, with a full 75% reporting that they will not purchase from companies they don’t trust to protect their data.
Data security is the practice of protecting digital information from unauthorized access, corruption, or theft throughout its entire lifecycle. It’s a concept that encompasses every aspect of information security from the physical security of hardware and storage devices to administrative and access controls, as well as the logical security of software applications. It also includes organizational policies and procedures.
When properly implemented, robust data security strategies will protect an organization’s information assets against cybercriminal activities, but they also guard against insider threats and human error, which remains among the leading causes of data breaches today. Data security involves deploying tools and technologies that enhance the organization’s visibility into where its critical data resides and how it is used. Ideally, these tools should be able to apply protections like encryption, data masking, and redaction of sensitive files, and should automate reporting to streamline audits and adhering to regulatory requirements.
Software vulnerabilities are common. While not all of them are serious, even noncritical vulnerabilities can be combined for use in attack chains. Reducing the number of security vulnerabilities and weaknesses helps reduce the overall impact of attacks.
Taking a proactive approach to application security is better than reactive security measures. Being proactive enables defenders to identify and neutralize attacks earlier, sometimes before any damage is done.
As enterprises move more of their data, code and operations into the cloud, attacks against those assets can increase. Application security measures can help reduce the impact of such attacks.
Neglecting application security can expose an organization to potentially existential threats.
Application security, or appsec, is the practice of using security software, hardware, techniques, best practices and procedures to protect computer applications from external security threats.
Security was once an afterthought in software design. Today, it’s an increasingly critical concern for every aspect of application development, from planning through deployment and beyond. The volume of applications developed, distributed, used and patched over networks is rapidly expanding. As a result, application security practices must address an increasing variety of threats.
How does application security work?
All appsec activities should minimize the likelihood that malicious actors can gain unauthorized access to systems, applications or data. The ultimate goal of application security is to prevent attackers from accessing, modifying or deleting sensitive or proprietary data.
An application firewall is a countermeasure commonly used for software. Firewalls determine how files are executed and how data is handled based on the specific installed program. Routers are the most common countermeasure for hardware. They prevent the Internet Protocol (IP) address of an individual computer from being directly visible on the internet.
Finding and fixing vulnerabilities reduces security risks and doing so helps reduce an organization’s overall attack surface.
Network security is the operation of protecting data, applications, devices, and systems that are connected to the network. An IT infrastructure of an enterprise, including its networking components, hardware, operating systems, software, and data storage. Network security protects these systems from malware/ransomware, distributed denial-of-service (DDoS) attacks, network intrusions, and more, creating a secure platform for users, computers, and programs to perform their functions within the IT environment.
As organizations move to hybrid and multi-cloud environments, their data, applications, and devices are being dispersed across locations and geographies. Users want access to enterprise systems and data from anywhere and from any device. A zero-trust approach to security, wherein an organization never trusts and always verifies access, is fast becoming the new method for strengthening an organization’s security posture.
Types of Network Security
- Firewall Protection
A firewall is either a software program or a hardware device that prevents unauthorized users from accessing your network, stopping suspicious traffic from entering while allowing legitimate traffic to flow through. next-generation firewalls that use AI and machine learning to compare and analyze information as it tries to come through.
- Intrusion Detection and Prevention
Intrusion detection and prevention systems (IDPS) can be deployed directly behind a firewall to provide a second layer of defense against dangerous actors. An advanced IDPS can even use machine learning and AI to instantly analyze incoming data and trigger an automated process – such as sounding an alarm, blocking traffic from the source, or resetting the connection – if it detects suspicious activity.
- Network Access Control (NAC)
It controls access to your network. Most often used for “endpoint health checks,” NAC can screen an endpoint device, like a laptop or smart phone, to ensure it has adequate anti-virus protection, an appropriate system-update level, and the correct configuration before it can enter. NAC can also be programmed for “role-based access,” in which the user’s access is restricted based on their profile so that, once inside the network, they can only access approved files or data.
- Cloud Security
Cloud security protects online resources – such as sensitive data, applications, virtualized IPs, and services – from leakage, loss, or theft. Keeping cloud-based systems secure requires sound security policies as well as the layering of such security methods as firewall architecture, access controls.
- Virtual Private Networks (VPNs)
A virtual private network (VPN) is software that protects a user’s identity by encrypting their data and masking their IP address and location. When someone is using a VPN, they are no longer connecting directly to the internet but to a secure server which then connects to the internet on their behalf. VPNs can protect users from hackers, who could steal anything from emails and photos to credit card numbers to a user’s identity.
- Endpoint Protection
Often requiring a multi-layered approach, endpoint security involves protecting all of the endpoints – laptops, tablets, smartphones, wearables, and other mobile devices – that connect to your network. Although securing endpoints is a complex endeavor, a managed security service can help keep your devices, data, and network safe using antivirus software, data loss prevention, encryption, and other effective security measures.
- Unified Threat Management (UTM)
With UTM appliances, organizations can reduce costs and improve the manageability of network protection and monitoring using multiple network-security tools such as firewalls, VPNs, IDS, web-content filtering, and anti-spam software.
- Secure Web Gateway
This security technology prevents unauthorized network traffic from entering the internal network and protects users and employees that may access malicious websites that contain viruses or malware. Secure web gateways typically include web-filtering technology and security controls for web applications.
An effective enterprise security programs enable the mission of the enterprise, not hinder it. Without an effective security program, enterprises leave themselves exposed and vulnerable to the malicious intent of countless numbers of bad actors and organized crime
In today’s cyber environment, an effective enterprise security program is imperative in order to protect the computing infrastructure upon which the enterprise is built
Enterprise security is the process by which an organization protects its information assets from infringement of confidentiality, integrity, or availability. In addition to specific technology implementations, enterprise security also includes policies and procedures which provide guidance on the who, what, why, and how to implement the protection mechanisms for an organization’s information assets.
The enterprise continually changes, so the effectiveness of the risk mitigation efforts and the overall enterprise security program must be continually assessed for effectiveness and improvement.
Endpoints are the target of many cyber attacks, and with shifts in corporate IT infrastructure are becoming more vulnerable to attack
The transition to remote and hybrid work models has transformed businesses’ IT infrastructures, moving corporate endpoints outside the enterprise network and its perimeter-based defenses. As endpoints become organizations’ first line of defense against cyber-attacks, they require endpoint security solutions to identify and block these threats before they pose a risk to the company.
Endpoint protection involves monitoring and protecting endpoints against cyber threats. Protected endpoints include desktops, laptops, smartphones, tablet computers, and other devices. Various end point security solutions can be installed on and monitor these devices to protect them against cyber threats regardless of where they are located on or off of the corporate network.
Increased support for remote work moves corporate endpoints outside of the enterprise network and its protections. Endpoint protection has always been important for defense in depth.
At the network level, the organization may restrict access to the enterprise network based on a device’s compliance with corporate security policies and least privilege.
Organizations may also install software directly on an endpoint to monitor and protect it. This includes both standalone solutions and ones that use an agent installed on the device to allow it to be centrally monitored, controlled, and protected. This allows an organization to monitor and protect devices that may not always be connected directly to the enterprise network.
The modern enterprise has a variety of different endpoints that face a wide range of potential cyber threats. Endpoint protection solutions come in several different forms, including:
- Endpoint Detection and Response (EDR)
- Endpoint Protection Platform (EPP)
- Mobile Threat Defense (MTD)
- Advanced Threat Protection (ATP)
Email is a common entry point for attackers looking to gain a foothold in an enterprise network and breach valuable business data. Hence, email security is necessary for both individual and business email accounts, and there are multiple measures organizations should take to enhance email security.
Email security solutions are secure email platforms used to prevent phishing scams that trick users into divulging privileged information. Our security solutions are the most cost-effective way to reduce spam levels and mitigate threats from phishing, malware, and ransomware.
With no hardware to purchase and no software to install, cloud-based email security solutions are quick and easy to implement, simple to administer and inexpensive to operate. The platforms, hosted by the cloud email security vendor, also ensure emails containing links to malicious sites or trigger malware downloads are blocked before reaching the end user.
Benefits of Email Security Solutions
Most of the cloud-based email security solutions are faster to deploy making sure email security gateway are up-and running in under an hour, with no lapse in security.
Cloud Email security solution has security protocols in place to protect sensitive information and transactions. This prevents a third party from eavesdropping or tampering with data being transmitted.
Incorporating malware protection within your email security strategy
In a world where companies routinely fall prey to hackers, malware protection has become critical to business success.
From viruses and Trojans to phishing and spear-phishing attacks, email security threats are among the biggest risks confronting organizations today. With email-borne threats responsible for more than 90% of hacking attacks, malware protection for email must be a cornerstone of IT strategy.
The right solution for malware protection must be easy to use and affordable, and it must stop 100% of threats before they reach the network.
Many enterprises are often vulnerable to DNS server security risks as they only use a couple of DNS servers. As a result, this may leave them incapable of protecting against volumetric attacks, whereby large amounts of traffic to a website may cause servers to crash, preventing users from finding the website. Having a DNS Security will help keep your website up and running and gives you a detailed overview of all assets on your clients. DNS Security prevents DNS forgery and manipulation.
DNS Security is the technology used to protect information on the Domain Name System (DNS). It provides authentication for the origin of the DNS data, helping to safeguard against attacks and protect data integrity.
A secured web has certainly created a need for businesses to have access to secured web gateway services. Stop malware with secure DNS protection before it enters your network.
Cloud security is a collection of procedures and technology designed to address external and internal threats to business security. Organizations need cloud security as they move toward their digital transformation strategy and incorporate cloud-based tools and services as part of their infrastructure.
The terms digital transformation and cloud migration have been used regularly in enterprise settings over recent years. While both phrases can mean different things to different organizations, each is driven by a common denominator: the need for change.
As enterprises embrace these concepts and move toward optimizing their operational approach, new challenges arise when balancing productivity levels and security. While more modern technologies help organizations advance capabilities outside the confines of on premise infrastructure, transitioning primarily to cloud-based environments can have several implications if not done securely.
Striking the right balance requires an understanding of how modern-day enterprises can benefit from the use of interconnected cloud technologies while deploying the best cloud security practices.
Integrating cloud into your existing enterprise security program is not just about adding a few more controls or point solutions. It requires an assessment of your resources and business needs to develop a fresh approach to your culture and cloud security strategy. To manage a cohesive hybrid, multi cloud security program, you need to establish visibility and control.
Malware protection is a robust cyber security solution that adds an extra layer of security to your computer to protect against cyber attacks. Once downloaded to your device, malware protection periodically scans your computer to identify, quarantine, and eliminate any malware to keep your systems secure.
Most common types of Malwares
- Worms – Entice users to click on malicious links, usually sent by email, to gain access to a system in order to replicate itself and spread to other computers.
- Trojans – Malicious code that downloads onto a device disguised as a legitimate program in order to gain access to a users’ system.
- Ransomware – a type of malicious software that infects a system and locks the user out of their files until a ransom is paid.
- Spyware and adware – a predatory software that hides a device and monitors activity to steal sensitive information such as bank details and passwords. It can also gain access to microphones and cameras.
To protect yourself against malware, include the best malware protection practices in your security protocols.
When it comes to securing corporate networks, NGFWs go beyond the call of duty compared to traditional firewalls. They’re able to collect a greater body of knowledge about malicious traffic and its embedded threats that are constantly trying to infiltrate the network perimeter, access corporate data, and ruin an organization’s reputation.
A next-generation firewall (NGFW) is the convergence of traditional firewall technology with other network device filtering functions, such as inline application control, an integrated intrusion prevention system (IPS), threat prevention capabilities, and antivirus protection, to improve enterprise network security.
A “deep-packet inspection firewall that moves beyond port/protocol inspection and blocking to add application-layer inspection, intrusion prevention, and bringing intelligence from outside the firewall.”
As advanced threats such as ransomware began to emerge, these stateful firewalls were easily bypassed day in and day out. Needless to say, an enhanced, more intelligent security solution was in high demand.The next gen firewall capabilities are actually a core requirement.
NGFW Features
Application control: NGFWs actively monitor which applications (and users) are bringing traffic to the network. They have an innate ability to analyze network traffic to detect application traffic, regardless of port or protocol, increasing overall visibility.
IPS: At its core, an IPS is designed to continuously monitor a network, look for malicious events, then take careful action to prevent them. The IPS can send an alarm to an administrator, drop the packets, block the traffic, or reset the connection altogether.
Threat intelligence: This can be described as the data or information collected by a variety of nodes across a network or IT ecosystem that helps teams understand the threats that are targeting—or have already targeted—an organization. This is an essential cybersecurity resource.
Antivirus: As the name suggests, antivirus software detects viruses, responds to them, and updates detection functionality to oppose the ever-changing threat landscape.
Actively searching for threats gives security analysts a way to find a compromise based on data collected in logs. Threat hunting features in a SIEM help with newly emerged threats that might be unknown. A new variant of malware in the wild could currently be undetected by antivirus software, but a SIEM might detect unusual traffic probing a network resource and alert SOC analysts so that they can further look into the issue.
Complex and advanced threats are difficult to eradicate from an environment. An advanced persistent threat (APT) will set up backdoors and additional ways to exfiltration of data even after initial eradication. Some variants of ransomware will replicate itself to storage across the network. If left on network storage, it can potentially reinfect the network and create another cyber-event that could impact data integrity. These threats are difficult to identify and completely remove from the environment, but a SIEM can help monitor and detect them so that analysts can remove the APT.
A SIEM is a collection of cyber security components used to monitor network traffic and resources. From a user perspective, it’s a centralized dashboard of security information used to display alerts and suspicious network activity to a security analyst. It’s a platform containing:
- Log aggregation from multiple sources
- Threat intelligence
- Event correlation and organization for easier analysis
- Advanced analytics visualization
- Customizable dashboards for analytics
- Threat hunting features to find currently compromised resources
- Forensics tools for investigation after a cyber-incident
The SIEM platform is used within a SOC, and security analysts work with these platforms in their day-to-day operations. One aspect of a SIEM not listed above is SOC automation. SIEM platforms integrate artificial intelligence (AI) to automate intrusion detection and prevention. A SOC analyst is still necessary for containment and eradication of the threat, but the SIEM will analyze network traffic, potentially block access, and send an alert to a security analyst to further research into the event.
In a data center or large enterprise environment, a SOC is necessary for network security. The SOC is often a physical room within the organization’s office where several employees continually monitor network traffic, alerts, and visualized information that could be used to respond to a potential cyber-incident. The SOC focuses on security of the network rather than network performance and utilization, which makes it distinct from a Network Operation Center (NOC), but SOC and NOC employees could be housed in the same physical location.
SOC perform a few standard functions:
- 24/7 continual monitoring across the entire environment
- Preventative maintenance and deployment of cybersecurity appliances
- Alert ranking to determine priority during incident response
- Threat response when a cyber-threat is found
- Containment and eradication of discovered threats
- Root-cause analysis after a cyber-incident
- Assessment and management of compliance for various regulations
An unmonitored network environment could have multiple threats breaching resources, but an intelligent SIEM provides the right information and alert system so that SOC can identify them.
Depending on the number of monitored resources, a SIEM collects potentially thousands of events and aggregates the information in one location.
The SOC team must configure the SIEM to give them the right alerts and detailed information so that they can quickly determine the right steps based on the type of threat detected.
Without a SIEM, a SOC team does not have the right tools to detect and contain threats.
In today’s hybrid world, a traditional hardware-defined network perimeter designed for a corporate office is no longer viable. An SDP not only reduces the risk to endpoints that connect from anywhere, but also with the help of an SDP controller distributes network resources more evenly. Because these resources are defined on an individual basis, access control is centralized as well as simplified, ensuring secure access throughout your entire organization
The software-defined perimeter, or SDP, is a security framework that controls access to resources based on identity. SDP hides an organization’s infrastructure — regardless of where it is located — from outsiders, while enabling authorized users to access it.
SDPs provide secure access to network-based services, applications and systems deployed in public and/or private clouds and on premises. The SDP approach is sometimes said to create a “black cloud” because it obscures systems by cloaking them within the perimeter so outsiders can’t observe them.
The SDP cybersecurity approach mitigates common network attacks, protecting all classification levels of legacy information technology (IT) assets, regardless of if they are in the cloud, on premises, in a perimeter network, or on a data center or application server.
An SDP functions as a broker between internal applications and users who can only provide access to services if the correct authentication and authorization criteria are met. As a “need to know” framework, an SDP only provides the information a user or device needs and nothing further. Therefore, an SDP does not share domain name system (DNS) information, internal Internet Protocol (IP) addresses or internal network port information.
Ransomware is one of the fastest-growing malware threats today and is already an epidemic.
Ransomware is malicious software (malware) used in a cyberattack to encrypt the victim’s data with an encryption key that is known only to the attacker, thereby rendering the data unusable until a ransom payment (usually cryptocurrency, such as RANSOMWARE Bitcoin) is made by the victim.
In the past, ransomware attacks that locked down a user’s computer or files could be easily reversed by a trained professional. But in recent years, ransomware attacks have become more sophisticated and, in many cases, have left the victims with little choice but to pay the ransom or lose their data forever.
A recent and notable change in many ransomware family variants is the addition of a data exfiltration feature. This new feature allows cybercriminals to exfiltrate sensitive data from victim organizations before encrypting the data. This exfiltrated data is like an insurance policy for attackers: even if the victims have good backups, they’ll likely pay the ransom to avoid having their data exposed.
Modern ransomware defense technology is not only highly effective but also easy to deploy. Sufficient ransomware protection begins with adopting a security posture that’s natively built in the cloud to protect users, applications, and sensitive data from these attacks, regardless of where users connect or what devices they’re using.
Advanced penetration testing is a simulated cyber security testing that checks exploitable vulnerabilities present in an enterprise IT environment. Advanced Pen testing may involve attempted breaching of application systems or front-end/back-end servers to discover security defects. Vulnerabilities arise from various sources, such as malicious inputs, which can be susceptible to code injection attacks. It is important that enterprise networks and applications undergo periodic penetration testing to overcome the challenge. Moreover, the testing assures that every probable security weakness is discovered and eliminated on time.
Our goal for advanced penetration testing is to verify the existence of known vulnerabilities that are easily exploitable by an attacker as they appear from outside the perimeter.
Advanced Penetration Testing Service
Preparation & Planning
We start by defining the scope of testing. It is an activity done jointly with the client. Our team assess all operational conditions and details connected to the machines, systems, and networks in scope. Hence, the security team can develop the right plan for carrying out the testing.
Information Gathering
We gather complete information regarding the hosts, network, and applications in scope. All these details are analyzed and correspond to valuable inputs while performing the testing process.
Threat Modeling
Threat modelling is a risk-based approach performed in the early stages of the red team assessment. It helps you map out the threats and provide context to the vulnerabilities and attacks as a part of the testing process.
Vulnerability Detection
Our team conducts processes like scanning the complete network with various tools, detecting open share drives, open FTP portals, ongoing services, etc. The process gets done from the point of view of an attacker that helps determine enterprise security control resiliency.
Vulnerability Exploitation
The identified vulnerabilities in the previous phase go further exploited in this phase. The process gets manually performed using commercial tools, custom scripts and the Powershell tool. These tools help pen testers explore large attack surfaces and exploit more possibilities. Here pen testers identify how severe a vulnerability can reach inside your environment.
Analysis & Reporting
The engagement delivers a detailed report of the assessment. It includes an Executive Summary for the management with detailed findings, risk ratings and remediation options. With this, patching efforts can go easy and flexible. The phase is also subject to the revalidation stage after successful patching.
ISO/IEC 27701:2019 is a service extension to ISO/IEC 27001. ISO 27701 Standard is the first global information privacy management standard that holds requisites, objectives and security controls related to the effective implementation of the Privacy Information Management System (PIMS). It also entails how organizations should effectively manage personal information and assist them in developing compliance with various other international privacy regulations.

Privileged user accounts are high value targets for cyber criminals. A criminal dealing in stolen credentials can make tens of thousands of dollars from buyers interested in purchasing them. And by selling those credentials to multiple buyers, organizations that experience a breach of credentials can easily be under digital assault from dozens or even hundreds of attackers.
Having a PAM system can reduce the need for administrators to remember many passwords and avoid privileged users creating local/direct system passwords. Session management and alerts helps the super-admin identify potential attacks in real time. A PAM allows to login faster to the systems they need and relieves the cognitive burden of remembering many passwords. It also enables the super user to easily manage privileged user access from one central location.
Privileged Access Management refers to systems that securely manage the accounts of users who have elevated permissions to critical, corporate resources. Cyber criminals are more interested in stealing credentials for privileged accounts than any other type of account. Thus, they present a challenge for IT departments.
IT department manages thousands of Endpoints. Managing these many endpoints is critical and hence easily opens the door for cyber attacks. Using multiple standalone security tools can complicate the threat detection and prevention process
A better approach is an integrated endpoint security solution. EDR solutions always come in multiple tools/layers. They feed intelligence into each other to successfully protect your organization from multiple angles. EDR allows you not to be dependent on platform constraints and be able to manage your environment wherever you or your teams are, at the time of your choosing.
EDR Solution refers to Endpoint Detection and Response Solutions that record and collect endpoint data using rule based automates response and analysis capabilities. EDR provides enhanced visibility into your endpoints and allows for faster response time. EDR tools detect and protect your organization from advanced forms of malware. To protect the endpoints, and to prevent them from being used as entry points into your infrastructure, your IT-security teams should be looking to boost your existing defenses. EDR solutions have several unique features and benefits which conventional Antivirus programs do not deliver. EDR security solutions are more suitable for today’s businesses as the traditional Antivirus has become an archaic security tool in terms of guaranteeing complete security. One of the factors driving the EDR solution is the increased sophistication of cyber attacks, which often focus on endpoints as easier targets for infiltrating a network.
The prime benefits of SD-WAN are its ability to allow direct access for a branch user to the cloud and SaaS applications. A secure SD-WAN must have the ability to restrict user access to a specific application, set application-based policies and monitor and log application usage
A software-defined approach to managing wide-area networks, SD-WAN offers improved connectivity to branch offices and the cloud. End users are excited about SD-WAN because it enables them to manage and add network functionality using a cloud-based software model, which eases deployment, enables central manageability and reduces costs. As compute resources and associated cloud services have exploded, the traditional enterprise network boundaries have expanded into the public cloud, branch locations and intelligent edges. Service providers, are increasingly providing managed
SD-WAN services to enterprises and the number of enterprise SD-WAN deployments is growing rapidly.
Existing security models cannot effectively address the evolving threat
The current protection model in the enterprise branch is basic and can’t
secure local internet breakout to the cloud, as traffic is steered over MPLS to
datacenter (DC) sites where security is applied. Also, there is not much
end-to-end micro-segmentation between branch and DC/cloud applications
across the enterprise.
With the increasing sophistication of attacks and evolving threat
landscape, we cannot assume that all attacks can be prevented by protective
controls. Currently there is not much visibility of branch user traffic. Visibility
and security analytics are crucial for detecting attacks.
Last, but not least, the current security provisioning model for applications is
largely manual and device-centric.
A stateful firewall filters packets based on the state and context of network connections and provides protocol inspection, such as TCP, UDP or ICMP, considering the STATE and CONTEXT of the flow, thereby eliminating additional attack surfaces.
The embedded security capability in the SD-WAN CPE network service gateway (NSG) uses signatures of known attacks to match traffic that passes through the NSG. IDS/IPS policies are defined and managed centrally or through API. Statistics and reports on intrusion event details and rule hit count are logged and signatures are updated dynamically from the cloud and applied to the NSG.
Web/URL filtering restricts branch user access to inappropriate or malicious internet content. It restricts local internet access to cloud services and whitelisted websites. Web filtering also helps mitigate malware and phishing attacks by blocking malicious webpages. Web filtering policies use a database that classifies URLs by category.
