eSentire is proud to be ranked #10 on the 2021 Top 250 MSSPs global listing by MSSP Alert as well as the top-ranked Managed Detection and Response (MDR) provider on the list.

Now in its 5th year, the Top 250 MSSP listing is updated every September and highlights the key market trends and insights across the industry’s top Managed Security Services Providers. The annual global survey results are based on a multitude of factors, such as business growth rate, cyber professional headcount, managed security services offered, third-party honors, MSSP Alert’s own editorial coverage of MSSPs worldwide, annual recurring revenues, and profitability.

As the top-ranked pure-play MDR provider on the list, eSentire was specifically called out for our commitment to 24/7 threat response, our acquisition of digital forensics leader CyFIR, and our industry-leading Incident Response capabilities:

"eSentire is a noteworthy MSSP move on this year's Top 250 MSSP listing," says Joe Panettieri, Executive VP and Editorial Director, MSSP Alert. "The firm rose from #37 in 2020 to a top 10 placement on this year's ranking due to their hyper-growth metrics, continued enterprise adoption and capabilities in Managed Detection and Response. As the top ranked pure-play MDR provider on the MSSP Alert Top 250, eSentire has delivered security services across over 1,000 organizations globally while leveraging a combination of XDR, 24/7 Threat Hunting and human-led investigations to respond with an impressive Mean Time to Contain of 15 minutes. eSentire's acquisition of CyFIR, a digital forensics and cyber investigations software provider, reinforces its incident response capabilities."

As the Authority in Managed Detection and Response, eSentire continues to deliver on our mission to hunt, investigate and disrupt advanced threats before they become business impacting events. Our service differentiators include:

Multi-Signal MDR Capabilities ­– eSentire MDR ingests signals across network, endpoint, log, cloud, email, identity, vulnerability, and insider threat sources to provide 24/7 threat detection and response for deeper visibility, enhanced correlation of security telemetry, automated threat disruptions, and minimized attacker dwell-time.
