Detection Engineering Driven By Our Elite Threat Hunters

eSentire MDR for Log is powered by dynamic threat detections and runbooks. The eSentire Threat Response Unit (TRU) manages this entire process for you, building proprietary detectors and runbooks for multi-signal environments, all mapped to the MITRE ATT&CK framework. Team eSentire ensures that your defenses evolve with the threat landscape.

Based on Threat Intel Research and MITRE Mapped

We investigate the latest threat actor tactics, techniques and procedures on an ongoing basis through original research, leveraging enriched threat intelligence, and the MITRE ATT&CK framework.

Developed to Proactively Identify Threats and Streamline Investigations

We provide visibility and early detections for emerging attacks with proprietary security content continuously created by our Threat Response Unit (TRU) and applied to our cloud-native Atlas XDR platform. Early detections are investigated, correlated across signal types to identify potential attacker movement across environments, and where necessary, active threats are rapidly contained within a 15 minute Mean Time to Contain.

Measurement and Continuous Improvement of Detections

We track all security content for accuracy and efficacy after deployment, implementing adjustments and decommissioning as necessary for optimized operational efficiency.

Machine Learning Innovation: Malkara

Developed by the Threat Response Unit

With more employees working remotely than ever before, most organizations have VPN or similar network access mechanisms in place to facilitate remote access. The problem is, attackers who have obtained valid account credentials can leverage VPNs or network gateways as a way to “walk in the front door” of your network undetected. MITRE ATT&CK classifies this technique as T1078 – Valid Accounts and it’s typically one of the more difficult techniques to identify before it’s too late.

To take on this challenge, eSentire’s TRU developed a proprietary machine learning model code-named Malkara as part of eSentire’s MDR for Log service. The model analyzes all remote access sessions leveraging data from VPN technology and cloud IAM controls from AWS, Azure, and GCP to identify any anomalous activity and the end user who triggered the alert. eSentire SOC analysts follow investigative runbooks to determine the validity of the event and if the activity is determined to be malicious, take action available to them to contain the threat.

We have immediate visibility into attempts to penetrate our network and feel better knowing that eSentire’s MDR is manned 24/7 with experienced cybersecurity experts."

The nice thing with eSentire is, they’re always looking at my network. They’re looking at my environment. They’re looking at everything that’s coming through. I can sleep at night. I don’t have to have 24/7 SOC. I know that my network is being looked at and they’re taking care of it. And if they see something that they deem to be a threat, they can prevent it, and block it, and stop it, and get a hold of my team, if needed."
