Audit evidence

How is AffixIO proof-not-log different from a SIEM?

A SIEM aggregates operational events. AffixIO proof-not-log stores signed decision digests in a tamper-evident structure auditors can verify independently. Use both: SIEM for operations, proof-not-log for defensible allow or deny evidence.

Security information and event management tools collect logs for detection and response. Those logs are mutable and often incomplete for proving a specific policy decision.

Proof-not-log appends cryptographic decision evidence. Auditors can check inclusion without reading conversation content or rebuilding the full application state. AffixIO is not a SIEM replacement. It is the decision proof layer SIEM and case systems can reference.

FAQ

Should we rip out SIEM?

No. Keep SIEM for ops. Add proof-not-log for decision evidence.

What gets hashed?

Decision metadata and policy version digests, not raw PII by default.
