On-Premises. In The Cloud. Hybrid. We're All-In To Protect You.
Cloud environments are incredibly dynamic. Most cloud threats stem from the misconfiguration and unaccounted use of the
cloud platform itself. In addition, many security leaders are challenged with having the in-house resources necessary to build, optimize, and manage their multi-cloud environments without requiring continuous manual monitoring.
At eSentire, we prioritize the detection of cloud-based vulnerabilities, misconfigurations, and suspicious activity across any cloud environment – no matter where your users and data reside – so you can focus on scaling your business operations securely.
We protect your multi-cloud environments and cloud based applications with 24/7 threat detection, investigation and response, combined with best-in-breed Cloud Security Posture Management and Cloud Workload Protection. Our cloud experts have a deep understanding of the refined tactics, techniques and procedures (TTPs) leveraged by attackers in multi-cloud environments. We provide seamless monitoring, scanning and control, delivering unmatched visibility, correlation and protection with MDR for Multi-Cloud environments across AWS, Microsoft and Google to protect your business from cloud-based threats including:

eSentire in Action
24/7 MDR With Azure Sentinel & Azure Active Directory (AD)
The Challenge
Threat actors commonly try to remove important security controls like multi-factor authentication (MFA) to gain or maintain access to a user account they have targeted.
Detection:
24/7 SOC Cyber Analysts are alerted via Azure Sentinel whenever MFA requirements are removed and follow a proprietary runbook to streamline the investigation process.
Response:
A sudden change in MFA requirements is very unusual and a potential indicator of compromise. With the right
context established and the eSentire Atlas XDR platform’s direct integration with Azure AD, our analyst can suspend
the credentials of the user who removed the MFA policy, minimizing the risk of any other important security policies being tampered with.
Threat Detection and Investigations in Google Cloud Platform (GCP)
The Challenge
Cloud infrastructure providers like GCP provide significant geographic regional control on where their data is stored.
Threat actors can use this to their advantage as a means of evading detection, by creating cloud instances in unused geographic service regions.
Detection:
eSentire has a proprietary GCP detector and investigative runbook designed to regularly scan for cloud administrative activity in typically unused GCP regions and our 24/7 SOC Cyber Analysts are alerted if such activity is identified.
Response:
Our analysts alert would alert you and confirm if the activity is expected or not. If not, SOC analysts would recommend the user’s credentials be suspended, perform further investigative work to determine if any other malicious admin activities happened, and find the initial intrusion source.
Why Multi-Signal MDR Matters
Our multi-signal approach ingests endpoint, network, log, cloud, asset and vulnerability data that enables complete attack
surface visibility. Automated blocking capabilities built into our eSentire Atlas XDR Cloud Platform prevent attackers from gaining an initial foothold while our expert Elite Threat Hunters can initiate manual containment at multiple levels of the attack surface. Through the use of host isolation, malicious network communication disruption, identity-based restriction and other measures, we can stop attackers at multiple vectors and minimize the risk of business disruption.
At eSentire we recognize that the attack surface is continuously evolving and expanding. While our MDR service protects your organization from modern attackers and the vectors they target most often, we are continuously analyzing and developing new services & detections to outpace the adversaries. In our 20+ history, we pride ourselves on the fact that no eSentire client has experienced a business disrupting breach. With over 1500+ customers across 80+ countries, we don’t just claim to deliver complete response. We prove it, and are proud to earn our global reputation as the Authority in Managed Detection and Response, each and every day.
