Our workflow

Passive Phase Reconnaissance

This is where we get to know your application or software. Our teams determine the scope of your project by examining the target system, its architecture, programming languages, and functionalities.

Active Phase Target Penetration

The real fun starts in this phase. Here, we do a deep dive with a full, manual penetration test of the target system based on our reconnaissance and previous findings. Fun fact: this process can account for up to 80% of the entire penetration testing cycle!

Reporting Debrief & Next Steps

Once the full testing cycle has been completed, we deliver extensive, no-holes-barred reports on all system vulnerabilities, from small insertion points to major security issues. With this, we can provide creative best practice solutions that work with your workflows and processes. We also outline fully the potential risks of each issue and how a malicious agent could exploit them.

"It was a pleasure working with the security team. They are extremely knowledgeable, capable, and very flexible; partnering with us and adjusting processes and communication to suit our needs. We are very much looking forward to an ongoing relationship between our teams."


"Cyrex have been consistently great security testing partners for us across a number of complex projects. Improbable often asks Cyrex to test brand new technology, posing a real challenge to testers to get up to speed with our cutting edge software, let alone find vulenrabilites within it. And yet we are consistently impressed by the quality of work we see. Cyrex keeps us one step ahead of our attackers."


"We worked with Cyrex on security and scale testing for our games and platform. They have the deep domain knowledge necessary to provide quality audits for complex software like games, and were a very friendly, responsive and commited team."
