What SIOS detects
Duplicate payment
Same vendor + similar amount billed twice within days.
Unused subscription
Recurring charges with no usage signal. Tools nobody uses.
Cost anomaly
Statistically abnormal spend vs. your baseline for that vendor.
Cloud waste
Dev and staging environments running 24/7, never turned off.
Every result is verifiable
SIOS generates a Computational Proof Object (CPO) — a SHA-256 fingerprint of every
input, output, and finding. Re-run detection on the same file and get the same proof.
Share it with your finance team, external auditor, or vendor.
