Penetration testing

Source Code Audit

Testing from the outside tells you what is reachable. Reading the code tells you why. A source code audit finds the logic and access-control flaws that never surface as an error message - and it finds them faster.

The paths data actually takes

We trace untrusted input from where it enters to where it lands, across most stacks and languages. Static analysis maps the baseline; a human decides which findings are real and which are noise.

  • Authentication, authorization and how sessions and tokens are handled
  • Injection, unsafe deserialization and command execution
  • Cryptography use, secrets handling and error and logging paths
  • Design and logic flaws that dynamic testing cannot see from outside

Manual review, SAST as support

Automated tools give coverage; they also drown you in false positives and miss anything that requires understanding intent. We read the code, use SAST to make sure we have not skipped a path, and confirm exploitability where we can. This is the same reading that turned a debug flag in a PRTG sensor binary into code execution as SYSTEM.

Findings tied to the line

  • Each finding located in the code, with the exploit path and a concrete fix
  • A management summary and a technical report with a clear order to fix in
  • False positives filtered out before they reach you
  • A walkthrough with a Q&A round, and a retest once you have remediated
