Black, Grey & White Penetration Testing

Penetration testing is a vital component of a comprehensive security strategy. It involves assessing the vulnerabilities of a system or network to identify potential weaknesses and to help improve its overall security posture.

What Is Black, Grey and White Pen Testing?

Penetration testing assignments are categorised according to the level of knowledge and access provided to the tester at the start of the testing process. This classification ranges from black-box testing, where the tester has limited information about the target system, to white-box testing, where the tester possesses extensive knowledge and privileged access.

In the middle is grey box testing. This spectrum enables the selection of appropriate testing methodologies based on specific circumstances.

Certified by CREST and Offensive Security, our qualified testers employ real-world hacking techniques to uncover profound insights.

It was a pleasure working with the Equilibrium team - they were very understanding of our needs, worked very well with my team, and most importantly were very patient and understanding of the limitations of my team to provide the information required when needed due to other priorities.
