eSentire

eSentire was among the first companies to offer MDR as a commercial service, and they have consistently led the market in both technology depth and human expertise. Their 15-minute Mean Time to Contain is one of the fastest response SLAs in the industry. They protect 2,000+ organizations across 80+ countries in 35 industries, including $6.5T+ in assets under management for financial services clients. Their Threat Response Unit (TRU) publishes original threat intelligence research, and their Atlas XDR platform is proprietary — not a resold SIEM.

Atlas XDR is eSentire proprietary open XDR platform that ingests high-fidelity signals across endpoint, network, log, cloud, and identity sources — processing 20 million signals daily. It drives both automated threat disruption (3 million daily) and the 24/7 human-led investigation workflow (6,000 daily investigations). Because it is proprietary and not a resold SIEM, eSentire can tune detection logic and response automation specifically for each customer environment.

eSentire 24/7 Elite Threat Hunters are named, dedicated security analysts assigned to each customer account — not a shared SOC analyst pool. They proactively hunt for threats, investigate alerts, and execute response procedures when threats are confirmed. The named assignment model means analysts build contextual knowledge of each customer environment over time, improving detection accuracy and reducing response time compared to rotating shared analyst pools.

Mean Time to Contain (MTTC) measures how quickly eSentire detects, investigates, and stops a confirmed threat. eSentire average 15-minute MTTC is significantly faster than the industry average, which can be hours or days. For organizations in regulated industries, financial services, or healthcare — where breach notification requirements, ransomware impacts, and regulatory penalties make rapid containment critical — the MTTC differential is material.

eSentire holds SOC 2 (AICPA certified) and ISO/IEC 27001 (BSI certified) certifications, and their platform is MITRE ATT&CK mapped. Their MDR service supports customers achieving HIPAA, PCI DSS, CMMC, NIST, and other compliance frameworks — 65% of their global customer base is recognized as critical infrastructure.
