It powers our eSentire MDR service, adding efficiency and value to your security operation by automatically blocking 3M attacks each day, without even notifying our SOC or your team. Atlas XDR cuts the noise, letting our experts focus on high priority security events.

Atlas XDR leverages patented artificial intelligence and scalable machine learning to process all the threat signals across our global customer base, making the eSentire proactive Security Network Effects possible. When Atlas XDR detects a threat it automatically responds, and pushes new detection and containment knowledge to every eSentire customer. Plus, eSentire Atlas XDR is always learning, and improving. We add around 400 suspicious indicators every day to continue to harden your defenses.

eSentire MDR, powered by our Atlas XDR Cloud Platform delivers results.
Detection in seconds, automatic containment in minutes, and security network effects at scale.

The Atlas XDR difference

Artificial Intelligence for threat hunting pattern recognition, applied at scale to deliver Security Network Effects to all of our customers.

We architected Atlas XDR from the ground up with the singular purpose of enabling the industry’s most effective Managed Detection and Response service. Atlas provides security, reliability and redundancy at scale and on demand, so our services can grow with your business.


Our scalable, distributed platform ingests and analyzes massive amounts of data from signals across our expansive customer base.


Adaptive Machine Learning and Artificial Intelligence models eliminate noise, and provide real-time detection of threats, including zero-day attacks.


We implement threat-specific containment measures in seconds at the network, endpoint, cloud and identity levels across our entire customer base.


24/7 visibility into our global customer base combined with proactive threat hunting, open source intelligence (OSINT) and commercial threat feeds, inform the detection rules we continuously deliver.


Data is normalized and correlated from network, endpoint, logs, behavioral sources, vulnerability scans, cloud environments and identity assets to monitor your entire attack surface and enable effective investigation.


Automated defenses kick into action, blocking malicious IOCs and IPs known to eSentire. The SOC team intervenes to respond to more advanced threats requiring human intuition and investigation.

This ability to rapidly learn and work at cloud scale, combined with expert human actions, stops breaches and reduces customer risk in ways unattainable by legacy security products, traditional MSSPs and other MDR providers.

See Atlas XDR in action

Watch the Atlas XDR Cloud Platform add value by automatically blocking threats that have bypassed your security controls. Atlas XDR automatically protects your assets against malicious IOCs and IPs known to eSentire, using a global IP blacklist that is updated in real time by our 24/7 SOC each time a new threat vector is identified on any monitored network.

There are 12,000+ indicators recognized across our eSentire Atlas XDR platform and we add 400 on average every day.

Enabling our cybersecurity experts

Machines are extremely capable when it comes to processing vast quantities of data and correlating signals to spot anomalous events, but that’s only part of what it takes to keep your business secure.

Threat investigations often require intuitive insight, manual exploration, and further threat hunting to put the pieces together and completely eradicate an intruder.

Atlas XDR filters out high fidelity threats, recognizing malicious IOCs and IPs that can be automatically disrupted and contained. That way, our SOC and Elite Threat Hunters spend their time on higher priority security events. If an orchestrated response isn't possible, Atlas XDR equips our cyber experts with the insights and tools they need to perform deep investigation and execute manual containment, when required, in minutes.

eSentire's rapid human led investigations are augmented by artificial intelligence pattern recognition and scalable machine learning models through the Atlas XDR platform. Atlas XDR learns from our team's actions, so it continuously improves to harden your defenses.
