Penetration testing

Web Application Penetration Testing

We test web applications by hand and, wherever you can give us the source, we read it. That combination is what finds the access-control and logic bugs a scanner reports clean.

The whole application, not the surface

We work from the OWASP Testing Guide as a floor, not a ceiling. Automated tooling maps the baseline; the findings that matter come from a person following the logic.

  • Authentication, session handling and multi-tenant isolation
  • Access control, horizontal and vertical, which is where most real breaches start
  • Injection, deserialization and server-side request forgery
  • Business-logic flaws that only make sense once you understand the app
  • Known-vulnerable components and how they are actually reachable

Manual, source-assisted

We prefer white-box testing. With the source and a set of accounts, we trace a suspicious response back to the line that produced it and prove whether it is exploitable, rather than guessing from the outside. Where source is not available we test black box and lean harder on reverse engineering. Either way, every finding is something we reproduced, not something a tool flagged.

A report your engineers can act on

  • A management summary in business terms and a technical report with every finding reproducible
  • Severity rated on real exploitability and impact, with a clear order to fix in
  • A concrete remediation for each finding, and a mitigation where it buys time
  • A walkthrough with a Q&A round, and a retest once you have remediated
