Expel

Expel is a managed detection and response provider that blends security operations expertise with AI-driven automation across your existing cloud and on-premises stack.

Overview

Expel works as an extension of your security team, monitoring the tools you already run — cloud platforms, SaaS, endpoints, identity, and network — through API-based integrations rather than rip-and-replace. Its operations platform applies automation and machine learning to triage alerts before human analysts engage, so customers see fewer, richer notifications with clear recommended actions. Transparency is a core design principle: customers can watch investigations unfold in real time through the Workbench console, complete with the evidence and reasoning used. The service covers detection, response, and remediation, including taking actions like isolating hosts with customer-defined approval workflows. Quarterly reviews translate activity into posture improvement recommendations rather than raw alert counts. Expel’s automation handles the repetitive steps of investigation — enrichment, correlation, scoping — allowing its analysts to spend time on judgment, which is where human expertise actually adds value in a security operation.

Who Is It For

Organizations that want MDR coverage integrated with the security tools they already own, and security leaders who value transparency and measurable outcomes over black-box managed services. It fits lean security teams that need 24/7 coverage and expert response capability without building and staffing a round-the-clock operations center themselves. Compliance teams gain evidence packs that document monitoring coverage and response actions throughout the reporting period.
