How We Do Cloud Security

Team: 24/7 Management Of Your Cloud Security Posture

We actively manage your cloud security posture and reduce risk by improving cloud visibility, tracking assets and monitoring for security vulnerabilities. Our 24/7 SOC Cyber Analysts and Elite Threat Hunters detect emerging cloud security threat tactics before they impact your AWS resources. They are supported by eSentire’s industry-renowned Threat Response Unit (TRU) who identifies the latest attacker techniques with proprietary cloud detectors mapped against the MITRE ATT&CK framework.

The cloud-native Atlas XDR Platform is the foundation of eSentire MDR, providing security, reliability and redundancy at scale and on demand, so our services can grow with your business. Leveraging patented machine learning and artificial intelligence models, Atlas ingests over 20M signals daily, automatically disrupting 3M threats to filter out high fidelity malicious events so our 24/7 SOC and Threat Response Unit can deliver 6000 daily human-led threat investigations, with a mean time to contain of 15 minutes.

Operations: Proven Cloud Security Processes
