MDR Alternatives to CrowdStrike Falcon Complete in 2026

# MDR Alternatives to CrowdStrike Falcon Complete in 2026

CrowdStrike Falcon Complete is the MDR benchmark for large enterprises, but the requirement to run Falcon EDR underneath it, the enterprise-only pricing, and lingering questions from the July 2024 outage lead many organisations to evaluate genuinely tool-agnostic alternatives. This guide covers the strongest ones.

Expel: the most transparent operating model

Expel Workbench shows customers exactly what analysts are doing in real time, and response actions are negotiated and documented explicitly during onboarding rather than left ambiguous. Genuinely tool-agnostic, working with whatever EDR and cloud stack a customer already runs.

eSentire: two decades of pure-play MDR specialisation

One of the founding pure-play MDR specialists, with bundled incident response that regulated buyers value having included rather than negotiated separately. Strong emphasis on measurable response time commitments as a core differentiator.

ReliaQuest: a genuine security operations platform, not just a service

GreyMatter gives customers direct visibility and control alongside the managed service, with built-in automation sophisticated enough to rival dedicated SOAR platforms. The right choice for large enterprises wanting more than an outsourced alert pipeline.

Arctic Wolf: the highest customer satisfaction in the category

100 percent willingness to recommend in Gartner Peer Insights Voice of the Customer, with a Concierge Security Team model providing named, dedicated analysts and genuine tool agnosticism across any existing EDR platform.

What none of these require

Unlike CrowdStrike Falcon Complete, none of these four require adopting a specific proprietary EDR sensor as a prerequisite. This is the core reason organisations evaluate them: keeping existing EDR investment while adding managed detection and response from a vendor that works with it rather than replacing it.

Our recommendation

Organisations wanting maximum transparency into analyst actions should evaluate Expel first. Regulated industries wanting bundled incident response should consider eSentire. Large enterprises wanting a genuine security operations platform should evaluate ReliaQuest. Organisations prioritising the strongest customer satisfaction track record should default to Arctic Wolf.
