What is Expel?
Founded in May 2016 by ex-Mandiant/FireEye veterans Dave Merkel, Justin Bajko, and Yanek Korff, Expel takes a deliberate stance: no proprietary agent, full transparency into SOC activity via the Workbench portal, and integration with whatever security tools the customer already owns. The company reached unicorn status in November 2021 and was named a Leader in The Forrester Wave for MDR Services, Q1 2025. Independent and private.
Best for: Teams that already own a quality EDR/SIEM/cloud stack and want a transparent, vendor-neutral SOC layered on top
Pros
- Genuinely vendor-neutral: no Expel agent, integrates with existing EDR/SIEM/cloud stack
- Transparent operations via Workbench (customers see every analyst action in real time)
- Strong public commitments such as a 13-minute MTTR for critical threats
- Founding team's Mandiant lineage gives credibility in IR and detection engineering
Things to check
- 'Bring your own tech' means customers must already own (and license) suitable EDR/SIEM/cloud tooling
- Premium pricing relative to bundled MSSP offerings
- Limited public pricing; sales-led
