Company Overview
About Expel
Expel is a Herndon, Virginia-based managed detection and response (MDR) company founded in 2016 that provides 24/7 security monitoring, threat detection, and incident response as a managed service. Rather than replacing a customer's existing security tools, Expel integrates with the tools organizations already have — SIEMs, EDRs, cloud platforms, and identity providers — and applies AI-powered automation and expert human analysis to triage alerts and respond to threats around the clock.
Business Model & Competitive Advantage
Expel's platform covers multiple attack surfaces: cloud environments (AWS, Azure, GCP), endpoints, identity (Okta, Azure AD), email, and network. The company's automation engine handles high-volume, low-complexity alert triage, allowing human analysts to focus on complex investigations. Expel reports dramatic reductions in mean time to respond (MTTR) and false positive rates compared to in-house SOC operations.
Competitive Landscape 2025–2026
Expel achieved a valuation of $1B+ with $142M in revenue and 508 employees. In Q1 2025, the company was named a Leader in the Forrester Wave for MDR Services with 5/5 scores across 15 of 21 evaluated criteria, including cloud detection, identity monitoring, and roadmap. In November 2025, Expel integrated with Google SecOps, expanding coverage for Google Cloud customers. The company also launched Expel Intel in October 2025, formalizing its threat intelligence capabilities as a standalone service offering.
