About GreySurface

I focus on authentication, access control, and data exposure in business software, particularly SaaS platforms.

My approach is systematic and tooling-assisted. I use automation to find candidate issues, then verify the security boundary by hand, document the result, and report it privately to the vendor under my coordinated disclosure policy.

I work in writing and asynchronously, which keeps engagements efficient and well documented.
