Whitebox Penetration Testing

Full-knowledge assessments of your applications and infrastructure, using source, architecture, and credentials to find what a blackbox test would miss.

Discuss This Service

Blackbox testing tells you what an outsider can see in a limited window. Whitebox testing tells you what's actually there.

We work with your team to get access to source code, architecture documentation, and application credentials up front, so engagement time goes toward finding and validating real issues instead of mapping the attack surface from scratch. It's the same posture a well-resourced, patient attacker eventually reaches. We just get there on day one.

How we work

Engagements are scoped around your systems and constraints, not a fixed template. Typical phases:

  1. Scoping and access. Define targets, gather credentials and source, agree on rules of engagement and timing.
  2. Testing. Manual analysis and exploitation, informed by code and architecture review, layered with targeted automated tooling.
  3. Validation. Every finding is manually verified before it goes in the report. No unvalidated scanner output.
  4. Reporting and walkthrough. A findings report your engineers and leadership can both use, plus a live readout.
  5. Retest. Confirm remediations actually close the gap.
