In today's interconnected world, cyber threats are not only growing in frequency but also in their potential for devastation. Data breaches can lead to sensitive information being stolen, which can result in significant financial losses, damaged reputation, and legal consequences.

Faced with these challenges, it's essential for businesses to proactively identify and address vulnerabilities in their IT systems. Penetration testing is a vital tool in this process and CTG’s Penetration Testing Service provides the expertise and tools needed to assess, reinforce, and maintain your organisation’s cyber security. Our expert cyber security team will help ensure you'll always be several steps ahead of potential threats.

What is Penetration testing?

Penetration testing, often referred to as "pen testing" or "ethical hacking," is a method used to evaluate the security of a computer system, network, or application. Rather than waiting for a malicious actor to discover vulnerabilities, penetration testing proactively tries to exploit any weaknesses, mimicking the actions of potential attackers. This assessment is conducted in a controlled environment and aims to identify vulnerabilities that could be exploited in real-world attacks, including potential paths that cybercriminals might use to gain unauthorised access or data. By simulating these attacks, organisations can gain a comprehensive understanding of their security controls and, subsequently, take necessary measures to bolster their defences.
