Expel is a managed detection and response (MDR) provider whose vision is to make great security as accessible as the internet.
Expel offers 24x7 security monitoring and response for cloud, hybrid and on-premises environments.
Expel was founded in 2016 by Dave Merkel, Yanek Korff and Justin Bajko. The company is headquartered in Herndon, Virginia.
Expel’s disruptive SaaS-based platform, which automates ‘detect’ and ‘respond’ postures, is helping security teams manage a significantly increased volume of cyber threats and secure their complex cloud-native environments.
Expel uses the security signals customers already have so organizations can get more value from their existing security investments. It connects to customer tech remotely through APIs, so its SOC can start monitoring a customer’s environment in a matter of hours.
Expel provides metrics so that customers can evaluate their investments and ensure they’re focusing on the most important aspects of their business. The company’s customers include the likes of Delta Air Lines, DoorDash, Better.com, Esri, GreenSky and CDW.
Expel is backed by CapitalG, Index Ventures, Scale Venture Partners, Greycroft, Paladin Capital Group, Cisco Investments, March Capital, and others. The company raised $140.3M in Series E round on Nov 18, 2021. This brings Expel's total funding to $257.9M to date. The latest round valued the company at over $1B post-money.
