No. Detection is driven by deterministic rules. ARYA SAI only produces advisory summaries from redacted evidence, and every containment action requires a named human approver.
You choose UK (London) or EU (Frankfurt) residency at onboarding. Additional regions are available on Enterprise plans.
CSH Compliance helps you prepare evidence for these schemes. We do not claim certifications we have not been awarded; our own certification status is published on the Trust page.
Only assets you have verified ownership of via DNS or HTTP token. Unverified assets cannot be scanned or ingested.
Yes. The partner edition supports delegated tenants, pooled licensing and partner billing.
