Frequently asked
Q. How does the audit relate to Aegis, the open-source toolkit?

A. Aegis automates the horizontal controls (headers/CSP, rate limiting, validation, CSRF, secrets hygiene) and flags the vertical risks it cannot fix — authorization/RLS design, tenant isolation, business logic. The audit is a human closing exactly those. It complements secure design; it does not replace it.

Q. What's the turnaround?

A. A spot review takes a few days; a standard audit is roughly 1–2 weeks depending on surface area. I confirm scope and timeline with you before any work begins.

Q. Do you work remotely?

A. Yes — fully remote and async-friendly, across time zones.

Q. Can we sign an NDA first?

A. Yes, before any scoping call. Your template or mine.
