The challenge
The client was preparing for an external audit and could not produce the file-change history or alert-on-change evidence required. Existing SIEM coverage was limited to perimeter devices, leaving critical file servers unmonitored.
What we built
We deployed file integrity monitoring on the in-scope servers, integrated it with the SIEM, and tuned alerts to surface change events that matter (binaries, configuration files, scheduled tasks) while suppressing routine noise. We built dashboards the security team and the auditors could both read.
What changed
Detection time for unauthorized changes moved from days to minutes. The client passed the audit with a clean report and now has continuous evidence on file. The platform is documented end-to-end so the in-house team owns it post-engagement.
