Deterministic Sigma Correlation
Versioned Sigma rules evaluate normalised Linux, Windows, AWS CloudTrail and OpenTelemetry streams against MITRE ATT&CK with zero opaque black-box scoring.
Passive factory-floor visibility, IEC 62443 zone segmentation and safety-engineer gated workflows. (Custom volumes, dedicated data residency, SSO/SCIM and delegated multi-tenant management for partners.)

Observes industrial ICS/SCADA and clinical IoMT traffic exclusively through passive network taps with owner sign-off.
Models safety-critical production lines, conduits and asset criticality hierarchies.
Policy OT-SAFETY-001 prohibits active vulnerability scanning, packet injection, firmware flashing or automated shutdowns.

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.
