Curated Supplier · MDR / XDR

eSentire — top-tier MDR, not "AI-powered alerts."

Multi-signal Managed Detection & Response with a 15-minute mean time to contain — backed by Atlas XDR, the Threat Response Unit research team, and 24/7 SOC analysts who actually investigate. 2,000+ organizations across 80+ countries trust it precisely because it doesn't try to be everything for everyone. If you've outgrown alert-forwarding MSSPs, eSentire is the conversation.

What eSentire actually does.

eSentire is multi-signal MDR — they correlate detections across endpoint, network, log, cloud, and identity signals through the Atlas XDR platform, then have humans hunt and respond. The "Authority in MDR" positioning is earned by the depth of the Threat Response Unit (their internal research team) and the fact that they actually contain threats rather than just forwarding alerts to your team to deal with.

Capabilities · A short list

Who this fits.

Best Fit

Mid-market+ CISO with maturing security program

You've moved past basic MSSP. You want detection engineering that improves quarterly, threat hunting that finds the things automation misses, and SOC analysts who can be your team's extension.

Strong Fit

Microsoft-first orgs with E5 Security licensing

eSentire's Defender XDR and Sentinel offerings extract more value from the Microsoft investment than rolling your own SOC against the Microsoft consoles.

Mixed Fit

Heavy Cisco shops

If you're standardized on Cisco Secure Endpoint, Umbrella, Duo, and Secure Firewall, Cisco XDR may be the simpler integration story. Worth a comparison brief.

Less Likely

SMB or pre-revenue startups

Sub-$50K MDR budgets fit better with Field Effect or CyberMaxx. eSentire's ceiling is enterprise; the floor isn't bargain.
