Compliance
CMMC Level 2
We map all 110 NIST SP 800-171 Rev 2 controls to your actual AI usage. Every blocked prompt records which control it affects. Your SPRS score updates in real time.
HIPAA
Names, SSNs, MRNs, dates of birth, device IDs, IP addresses, and 12 more. If a prompt contains PHI, Hound Shield quarantines it and logs the event. You set the policy; Hound Shield enforces it.
SOC 2 Type II
Every AI prompt stored in an append-only log with a SHA-256 integrity hash. Your auditors get read-only access. No manual exports, no spreadsheets, no guessing what your team sent.
Every LLM request inspected before it leaves the network
CUI, PII, IP, PHI, secrets, CAGE codes, clearances — all matched
SHA-256 tamper-evident logs ready for any compliance audit
Works with ChatGPT, Copilot, Claude, Gemini — all simultaneously
