eSentire —
The Authority in Managed Detection and Response

eSentire is the right fit for mid-market and enterprise organizations whose security posture has to function as a business-continuity guarantee — financial services, legal, healthcare, biotech, professional services, and any operator whose downtime translates directly into client risk. Founded in 2001, eSentire protects 1,200+ organizations across 75+ countries spanning 35 industries. The operating model is purpose-built for organizations that have outgrown a generic MSSP and need a named Cyber Risk Advisor, 24x7 access to SOC analysts, elite threat hunters, and the threat-intelligence research published by the eSentire Threat Response Unit (TRU). It is positioned as a buyer's last-line-of-defense provider rather than a checkbox compliance vendor.

eSentire pioneered Managed Detection and Response as a category and operates one of the longest-running pure-play MDR practices in the industry. The 'Authority' positioning is grounded in three things: a multi-signal MDR architecture that ingests endpoint, network, log, identity, and cloud telemetry into a single XDR machine-learning detection engine; a 24x7 Threat Hunting team led by elite analysts who proactively look for adversary behavior across the customer base; and the Threat Response Unit (TRU), eSentire's in-house threat-intelligence and research arm whose findings inform detection rules, hunt hypotheses, and customer advisories. The result is mean-time-to-contain measured in minutes rather than hours.

Endpoint Detection and Response (EDR) competitors typically see only what happens on the endpoint — process telemetry, file activity, and registry changes. eSentire's multi-signal MDR architecture ingests endpoint signals plus network packet inspection, log aggregation across cloud and on-premises, identity provider events, and SaaS perimeter telemetry into a single XDR detection layer. That breadth matters because most modern attacks chain across signals: an identity compromise that pivots through a SaaS app and lands on an endpoint will only be visible end-to-end if the MDR provider sees all five signal types. EDR-only providers will see the endpoint stage and miss the upstream lateral movement.

Digital Forensics and Incident Response (DFIR) is eSentire's emergency-response practice for organizations either under active attack or recovering from one. It is available both as a retainer for existing MDR customers and on demand for non-customers facing a breach. The DFIR team handles forensic acquisition and analysis of compromised systems, attacker eviction, evidence preservation suitable for legal and regulatory reporting, and post-incident hardening recommendations. For MDR customers, the integration matters: the same telemetry the SOC was watching is available to DFIR as forensic ground truth, so investigation and recovery start from a richer evidence base than a cold-start incident-response engagement.

Managed Risk is eSentire's proactive-program offering that complements MDR's reactive posture. It covers vulnerability scanning, vulnerability prioritization based on real-world exploit telemetry from TRU, phishing simulation and security-awareness training, third-party-risk advisory, and named Cyber Risk Advisor engagement that gives the customer a single point of contact for board reporting, security-program guidance, and compliance alignment. The intent is that Managed Risk closes the gaps that MDR detects — so the customer's posture improves over time rather than perpetually responding to the same classes of attack.
