    Frequently Asked Questions

    Both read and team and blue team play equally important roles in cybersecurity. While the red team helps you identify threats by way of simulating real-world attacks, the blue team helps you identify how strong you are in defending them. 

    Involving the red team in penetration testing helps you see to what extent an attacker can go into uncovering vulnerabilities in your systems and exploiting them. This will give you a more realistic picture of the threats as well as limitations and help you improve them more strategically. 

    Both red teaming and penetration testing are part of the cybersecurity assessment procedure. Red teaming refers to the comprehensive procedure of performing simulated attacks. On the other hand, penetration testing is the evaluation of the security posture within an organization’s infrastructure – network, cloud, computer systems or whichever is specified before the test. 

    It is possible for a single individual to gain expert knowledge of both red team and blue team testing strategies and handle both roles simultaneously. However, it is recommended to have two different people do it during a planned red team vs blue team cyber security exercise to ensure more focus on each team’s steps. 

    Blue teams help organizations in improving security posture by letting them have a realistic knowledge of their existing defence. 

    Organizations can ensure maximum security posture by implementing a balanced approach to red team vs blue team cybersecurity. Red teams simulate sophisticated real-world attacks and thus help an organization identify new vulnerabilities. Meanwhile, blue teams focus on improving the defence and response strategies. This balanced approach helps an organisation develop a more proactive threat reduction strategy and implement continuous improvement.



    After the penetration testing is concluded, the testing company will provide the client with a detailed report of the test – what steps they took, what vulnerabilities were assessed and exploited and remediation steps to address the vulnerabilities. Follow the remediation steps carefully as early as possible. 

    Web application penetration testing services focus on evaluating and analysing the security of web applications. They look at challenges specific to web applications, for instance, issues with input validation, session management, business logic vulnerabilities etc. On the other hand, normal pen testing services will focus on the entire infrastructure such as computer systems, networks, and other resources within their testing scope.
