An Attack On You Is An Attack On Us

We stand with you, every moment of every day and push boundaries, to keep you ahead.

With hybrid working and cloud-services expanding your threat surface, cybercriminals becoming increasingly sophisticated and security expertise harder than ever to find, we understand how challenging it has become to protect your businesses from disruption.

To respond fast and mitigate business risk, you need complete visibility and coverage of your cyberattack surface which we uniquely deliver through our multi-signal approach to MDR. Our powerful Atlas XDR Platform ingests network, cloud, log, endpoint and insider threat signals, correlating indicators of compromise to detect, respond and automatically disrupt threats in minutes - with a Mean Time to Contain of less than 15 minutes. Our 24/7 SOC Analysts and Elite Threat Hunters rapidly respond to investigate, contain and stops threats the Atlas XDR Platform senses have the potential to bypass automated security controls.

Security without compromise

Don’t settle for partial security. Multi-signal matters.

At eSentire, we believe a multi-signal approach is paramount to protecting your complete attack surface. eSentire MDR means multi-signal telemetry and complete response. Whether your environment is in the cloud, on-premises or somewhere in between we have the visibility to see what other MDR providers will miss.

Our multi-signal approach ingests high-fidelity data sources from endpoint, network, log, cloud, insider threat, assets, and vulnerability data that enables complete attack surface visibility. Automated blocking capabilities from our eSentire Atlas XDR Cloud Platform prevent attackers from gaining an initial foothold while our expert Elite Threat Hunters can initiate human-led investigation and containment at multiple levels of the attack surface. Through the use of host isolation, malicious network communication disruption, account-based suspensions and other measures, we can stop the attacker at any level.
