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.
Audits cadrés, revues de sécurité IA et surveillance gérée réalisés par nos ingénieurs sécurité. (Business-hours monitoring by default, with clearly scoped extended-hours retainers.)

Linux syslog, Windows Event Forwarding, AWS CloudTrail, OpenTelemetry and webhooks.
Every raw event is checksummed with SHA-256 and kept read-only for the retention period.
Readable, testable detections mapped to MITRE ATT&CK, with change history.
Duplicate events are recognised by key so retries never create duplicate alerts.
Redacted, evidence-linked advisory summaries with calibrated confidence.
Host isolation and credential revocation require a named approver.

Versioned Sigma rules evaluate normalised Linux, Windows, AWS CloudTrail and OpenTelemetry streams against MITRE ATT&CK with zero opaque black-box scoring.

Every alert is enriched with PII-redacted ARYA SAI evidence summaries while host isolation and credential revocation await explicit human step-up approval.

Advanced threat actors leverage legitimate operating system binaries (LOLBAS) to evade standard antivirus. Here is how our London SOC engineering team intercepted and neutralized a live intrusion in 3 minutes.
Adversary attempted lateral movement using an infostealer-harvested session token.

Non. La détection repose sur des règles déterministes. ARYA SAI produit uniquement des synthèses consultatives à partir de preuves expurgées ; chaque action exige une validation humaine.
