Pair hacking... because two minds are always better than one

We believe in the creative power of collaboration. That’s why our teams are at their best when they work in pairs. Our unique approach to pair hacking allows us not only to cut testing time in half but to create peer-reviewed and validated quality assurance loops that yield far more in-depth results.

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.
