A clean bill of health — and the proof to back it

The challenge

A logistics firm wanted a large internet-facing estate validated against current high-impact CVEs — reporting only vulnerabilities with a demonstrated, exploitable vector, not version-banner noise.

How it unfolded

1. Enumerated and fingerprinted roughly eighty public hosts across the testing window.
2. Actively tested each high-severity candidate CVE (mail-server RCE, edge-gateway memory-leak classes, device and portal CVEs, default-credential and service exposures).
3. Verified each was patched or non-exploitable — the edge gateway leaked no memory, the RCE vector wasn't reachable, reflected input was blocked by content-type and CSP.
4. Confirmed the few real, demonstrable issues: an exposed trace handler, anonymous FTP to an empty share, and missing SPF/DMARC.
5. Flagged one network block that was app-layer filtered to the tester's source and needs an allow-listed vantage to re-cover.

Impact

The perimeter was materially hardened; residual risk was limited to information disclosure and email spoofing.

Outcome

High assurance that the headline CVEs were genuinely patched — proven, not assumed — plus a short, exploit-validated fix list and a retest plan for the filtered block. We report the good news too, with evidence.
