Expel
Vendor-agnostic MDR that works on the SIEM and EDR you already bought.
Proof of life. Launched MDR coverage for the full AI attack surface, August 2026
About Expel
Expel is the MDR that refuses to rip out your stack. Analysts plus its Ruxie agent sit on the customer's Sentinel, Splunk, CrowdStrike, or Panther and take containment actions under a published MTTR.
2026 coverage now includes the AI attack surface, so employee misuse of models and AI-assisted intrusions land in the same Workbench as classic endpoint alerts.
