A firewall is a network security framework that monitors and manages incoming and outgoing network traffic based on predetermined security protocols. A firewall functions as a gatekeeper that controls the traffic between the network and application elements. It filters network- and internet-based traffic, concentrating on application-specific granular security type and helps detect application-specific attacks. In the recent years, firewalls have evolved from packet filter to next-generation to better protect corporate networks.

Third-generation firewalls are also known as Web Application Firewalls (WAF); they apply a set of rules to a Hypertext Transfer Protocol (HTTP) conversation that covers application-layer attacks, such as Cross-Site Scripting (XSS), Structured Query Language (SQL) injection attacks, and application-layer DDoS attacks, and protects application servers from security breaches and loss of critical business information. WAF solutions are deployed ahead of web servers to defend web applications from internal and external threats, control and monitor web applications, and help organizations achieve compliance requirements.

A Next-Generation Firewall (NGFW) is a part of the third-generation of firewall technology that detects and blocks sophisticated cyber-attacks by applying security guidelines at the application, port, and protocol levels. The NGFW systems perform various security functions, such as Deep Packet Inspection (DPI),

IDS/IPS, application control, packet filtering, email security, and threat protection using sandboxing, along with all the capabilities of traditional firewalls. Furthermore, the NGFW offers various deployment options, including hardware-based and virtual-based systems, and cloud-based applications.



Antivirus software is a set of programs that detects, prevents, and mitigates cyber threats caused by viruses. The antivirus software prevents, detects, and eliminates malicious activities, such as computer viruses, rootkits, adware, spyware, malware, Trojans, and worms. On the other hand, an antimalware is a software program that detects, prevents, and remediates malicious codes from being executed in a system. Malware is a broader term, encompassing virus and spyware that creates a threat to intellectual, personal, and financial information. The antivirus and antimalware segment has witnessed a tremendous growth in the recent years, due to the simplicity of operations in both, enterprise and consumer domains. Several threat actors are known to use common hacking tools that are often detectable using the antivirus software. Currently, organizations are deploying a range of antimalware products in their business to increase the diversity of detection and ensure that attackers cannot easily bypass a single antivirus.



NAC can be defined as a solution which requires a set of protocols to define and execute a business policy to gain access to the network. The policy is one which would help users access the network nodes securely. If these policy requirements are not met, the user cannot connect their device to the computer network. Authorization, authentication, policy enforcement, and mitigation of non-zero-days attacks are some attack categories which safeguard users. Some capabilities of the NAC include incidence response, policy lifecycle management, guest networking access, and security posture check.



DLP is a security approach that prevents the organizations sensitive data from being transmitted outside. DLP is a comprehensive network security solution that ensures the prevention of information loss while the data is in endpoint action, network traffic, or storage. It addresses data security needs when the data is at rest (providing perimeter security, network monitoring, internet access control, and messaging control), in use (providing Security Information and Event Management [SIEM], user monitoring, usage monitoring, application control, and Identity and Access Management (IAM), and in motion (endpoint security, mobile device protection, encryption, firewall, and physical media control). The DLP technology uses business rules, policies, and procedures. Sensitive data, such as secret company information, intellectual property, and financial information, is protected from unauthorized disclosure through the deployment of risk assessment measures, strict governance policies, and privacy policies. Email is the greatest risk vector for inbound and outbound threats for data loss. DLP solutions help prevent the transmitting of sensitive data in the organization to any unauthorized location through various communication modes.

The segment covers the market for DLP software that employs various techniques, such as keyword matching, traffic pattern analysis, network monitoring, and file tracking to help prevent data leakage. The growing insider threats and strict implementation of government regulations and laws are fueling the adoption of DLP solutions across the globe.



The process of detecting and preventing events that try to violate the confidentiality, integrity, or availability of data is referred to as the IDS/IPS. IDS/IPS is a network security solution that monitors networks and systems for identifying malicious activities, detecting information about the activities, attempting to prevent them, and finally reporting them. Network-based Intrusion Detection System (NIDS) can be used to detect attackers’ activities on internal networks. However, for an IDS to be useful, it needs a robust rule set. There are various types of IDS that include NIDS, Host Intrusion Detection System (HIDS), signature-based IDS, and anomaly-based IDS. NIDS monitors the inbound and outbound traffic of all the devices across enterprise networks. HIDS identifies malicious network packets that originate from inside the organization that a NIDS fails to identify. HIDS also detects malicious network traffic that originates from the host itself. Signature-based IDS compares the malicious network traffic against a database of known malicious threats. An anomaly-based IDS monitor networks the traffic and compares it against an established baseline.



SWG is a network security software solution that protects computers from user-initiated web traffic and enforces company policies. These solutions protect end users from various security threats and malware such as ransomware, which might infect the network and the terminal. These solutions also help in maintaining the privacy and confidentiality of important data, thus preserving their value within the enterprise. As web and internet access for employees is business critical and cannot be avoided, enterprises have been encouraging the application of SWGs for real-time protection against dynamic malwares, such as ransomware and strong policy enforcement.



The DDoS mitigation is a technique to overcome DDoS attacks on systems linked to the internet. A DDoS attack is aimed at disrupting the normal function of a website and therefore demands high security. It is planned and coordinated, and creates a false traffic that prevents normal traffic from getting through. This leads to the depletion of network bandwidth, computing power, and operating system data structure resources, and the inundation of network infrastructure. A DDoS attack is executed from a master system to a network of computers. It disrupts the functioning of many resources, such as networks, websites, servers, or endpoints. Denial of Service (DoS) attacks, on the other hand, aim at disrupting the functioning of the target machine by flooding it with false requests and making it unavailable for legitimate requests. DDoS attacks have become a real threat to enterprises. Enterprises need to forestall their applications, network solutions, and services to combat the evolving sophisticated DDoS attacks. DDoS attacks affect the application layer, protocol layer, and the bandwidth of the network. Enterprises use DDoS protection and mitigation solutions and services for adaptive defense against DDoS attacks. DDoS attacks affect the confidentiality, integrity, and availability of resources, which may result in billion-dollar losses for enterprises.



UTM is a single hardware or software system that provides multiple security functions to protect enterprises from evolving cyber threats. It is a combination and an integration of various security features that provide robust security to enterprise applications from threats. UTM, being an integrated solution, provides multiple functionalities, such as spam blocking, gateway anti-virus, spyware protection, intrusion prevention, and URL filtering. UTM solutions offer network security, web security, email security, and cloud security. These solutions protect the enterprise infrastructure from cyber threats, such as ransomware, phishing, and botnets. UTM solutions are extremely popular in SMEs, as they overcome the tide of sophisticated and blended threats from multiple vectors and secure business-critical broadband internet connections. Moreover, they are cost-effective and handle all security functions of an entire network. UTM vendors are continuously adding new security functions to the solution to support the emerging cloud computing and virtualization trend.



Vulnerability scanning refers to a security technique, which proactively identifies security vulnerabilities in computer systems, networks, or applications. A set of procedures is designed to assess an organizations’ critical assets and network infrastructure. Vulnerabilities arise owing to faulty programming and weak configurations, which leads to potential paths for anomalies to enter IT systems. The vulnerability scanners are capable of seeking out flaws in the organizations’ security posture. Moreover, it systematically audits internal networks that are connected over the internet to determine if and where a system can be exploited. Vulnerability scanning tools ensure strong security for data, employees, systems, and customers, by eliminating security gaps within an organizations’ network infrastructure. Today, organizations are incorporating vulnerability scanning solutions to keep pace with an ever-evolving risk and compliance landscape. These solutions help an organization to combat a wide range of risks related to technology, commerce, information security, and operation among others. The growth drivers of this vulnerability scanning solutions are the growth in the need for internal audit features and regulatory compliance mandates with an unprecedented pressure of strict adherence.



Sandboxing is a malware analysis tool, used to detect and restrict new and unknown malware and targeted attacks from entering an enterprise network. As the threat landscape is continuously evolving, organizations are struggling to address sophisticated and advanced threats. Malware can penetrate an enterprise network through emails, untrusted websites, and downloadable files, such as executables, compressed files, PDFs, and MS Office documents. A sandbox enables the detection of malware in such files, which are not known so far. Any newly detected malware is immediately informed to the vendor’s threat intelligence database and then to all other customers across the world. A pre-filter tool, mostly associated with the sandboxing solution reduces the latency in delivering safe contents to the end user by identifying known malwares through a signature-based matching technique. Files, coming from a suspicious source, are only quarantined by the sandbox, thus preventing any delay in delivering data.
