Review process
Four steps from scope to final report.
Work together throughout the review
You work directly with me from scope through remediation. I ask questions as I learn the system, explain what I’m testing and why, and adapt the review to the threat model. Where formal verification, fuzzing, or another technique fits the scope, we agree on it together. Fixes are discussed and rechecked before the final report.
Security Review
I’ll set up a dedicated GitHub repository and a real-time chat channel to share findings instantly. The review process will be manual with AI assistance, and I’ll create tests as needed.
Fix Verification
I’ll thoroughly review your implemented fixes and all related code changes to confirm every issue is fully resolved and no new bugs are introduced.
Final Report
You’ll receive a professionally formatted report including all the findings and corresponding fixes.
