Penetration Testing

The bugs an attacker would actually use.

Two- or six-week engagements. Authenticated access. Source-assisted where helpful. You get reproducer scripts so your team can verify every fix.

  • OWASP Top 10 coverage + custom business logic
  • Source-assisted code review of high-risk surface
  • Reproducer script for every finding
  • Re-test pass after you fix things
The work

What you actually get.

Authenticated flow testing

Every endpoint behind your login, ranked by what an attacker would target first.

Multi-tenant isolation

Cross-tenant IDOR, broken access control, RBAC bypasses. The bug class that causes the worst breaches.

Payments & billing logic

Race conditions, double-spends, coupon abuse, webhook validation. We've found them all and they're never theoretical.

File upload & processing

SSRF via file fetchers, image-processor RCE, arbitrary write to S3. The attack surface that hides in 'just upload a CSV'.

Process

A predictable, founder-friendly engagement.

  1. 01

    Scoping & rules of engagement

    We document exactly what's in scope, what's out, and what we won't touch (production data, paying customers, etc.).

  2. 02

    Testing

    Two-week sprint for a focused engagement, six weeks for full surface area. Daily check-ins, weekly findings reviews.

  3. 03

    Report + reproducers

    Each finding has severity, impact, reproducer script, and a remediation path your team can act on without us.

  4. 04

    Re-test

    Two weeks after you ship fixes, we re-test. You get a clean bill or a punch list — no theatrics.

Frequently asked questions

Default to gray-box (credentialed user accounts). Source-assisted (white-box) for the highest-risk surface area, with you in the loop.
