Built to solve a problem that kept appearing.

The problem showed up the same way every time. A security review, a compliance audit, or an incident investigation would reveal that PHI was already in Splunk. Tokens were already in CloudWatch. Audit trails that were supposed to be clean had been contaminated for months. Every team had already shipped the problem before anyone knew to look.

The standard response was to add post-ingest scrubbing, tighten sink-level masking, or write internal guidelines that rarely got followed. None of it worked reliably, because the problem was always framed as a pipeline problem when it was actually an emission problem.

Cerbi moves the enforcement point to where it belongs: the call site, inside the application, before any network call is made. CerbiStream enforces governance rules in-process on every log event. CerbiShield provides the central control plane that manages those rules across every service in the fleet without requiring anyone to update application code.

The goal is a product that makes the right behavior the default behavior — one that ships into existing .NET logging frameworks without requiring a rewrite and without adding latency to the hot path.
