BACKEND · AUDIT & FIXES

Your backend has gaps, and the last report didn't close them.

Too many security tests end at the PDF. This audit delivers findings with fixes: weaknesses in API, cloud and secure code, prioritized, and optionally fixed directly by the same person who tested.

The pain I keep seeing

Three patterns repeat in almost every backend audit:

Broken access controlFunctions and data can be reached through manipulated requests or IDs, the most common and most underestimated weakness class.

Unsafe APIs & trust in client inputClient input is treated as trustworthy without strict validation. That's where SSRF, injection and mass assignment come from.

Cloud hardening gapsMisconfigured storage, overly open network rules and missing least-privilege concepts make attacks needlessly easy.

How we lock the backend down

A structured audit with a clear result, understandable for developers and management alike.

1. API & code reviewAuthn/authz, input handling, session and token management: we review against OWASP ASVS and look at real attack paths.

2. Cloud & infrastructure checkNetwork rules, storage, secrets, identities: hardening gaps are identified and prioritized.

3. Fixes, not just findingsFindings ship with concrete code and config fixes, on request I implement the most critical myself.

Free initial analysis, in two steps

Both steps are free and non-binding. Afterwards you know where you stand, and what makes sense next.

Step 2 · Call with mini-findingsIn the free 30-minute call I review publicly visible hints about your systems beforehand and show you 1–2 concrete findings you can verify yourself. No slides, real starting points.
