Expel Tech Stack

AI-assisted managed detection and response across cloud, identity and SIEM

Computer and Network Security Herndon, Virginia 201–500 employees Founded 2016 Privately Held

Expel is a Herndon-based MDR provider whose service plugs into a customer's existing security tools rather than replacing them. Its project pipeline is unusually Microsoft-centric: Defender XDR and Sentinel detection coverage, signal mapping, and ingestion schema work, backed by an Iceberg, Glue and Lake Formation data layer. Hiring is accelerating and security-weighted at senior levels, while pain points around ingestion costs and alert noise mirror what its own customers face.
