Streamlining Security with eSentire MDR and Microsoft 365 Defender

Most organizations—even large enterprises—lack the in-house expertise and resources to properly manage security tools across environments, eliminate false positives, conduct investigations, and swiftly respond to cyber threats before they impact the business. This critical gap persists regardless of where data resides or the number of tools available.

The eSentire MDR with Microsoft 365 Defender offering addresses these challenges, enabling all eSentire partners and customers—and all Microsoft users—to benefit from Microsoft’s leading security capabilities across their Microsoft and hybrid environments.

On-Demand Webinar: The Story Behind MDR with Microsoft Defender

Since day one, our team has embraced the philosophy that we must think about security in everything we do. Consequently, we’re always looking for ways to improve our own cybersecurity posture, which is why we deployed Microsoft Defender. In particular, we valued:

• Deep integration with a platform that we were already using day-to-day

• Improved security workflows and outcomes

• The opportunity to consolidate and reduce spend on security tools/vendors

• Additional signals that enable our Atlas XDR platform to hunt for advanced threats

In addition to simplifying our operational overhead, we were able to improve our cybersecurity—particularly for email. Plus, we used the internal implementation to develop expertise and fine-tune the integration that we subsequently rolled out to our customers as the eSentire MDR with Microsoft 365 Defender offering.

As part of Microsoft’s Security Community Webinars series, we shared The Story Behind MDR with Microsoft Defender: How eSentire streamlined security for itself and its customers with Microsoft 365 Defender.

This webinar covered two topics:

• How we strengthened our own enterprise security posture, and realized tremendous cost savings, by introducing Microsoft 365 Defender

• How eSentire Managed Detection and Response (MDR) with Microsoft 365 Defender is already delivering terrific security outcomes for our customers

How It Works

eSentire MDR for Microsoft’s Integration with Microsoft 365 Defender enhances our ability to pull in events, perform investigations, and respond to limit the business impact of threats that have broken through into an IT environment. The signals provided by Microsoft’s security solutions are consumed, normalized, and correlated with additional security signals within our Atlas XDR platform, allowing our expert SOC analysts to investigate and respond to elusive threats that individual solutions might miss.

Therefore, businesses who are already part of the Microsoft ecosystem can use the combined eSentire MDR with Microsoft 365 Defender solution to get robust and more cost-effective security outcomes.

In addition, the Microsoft Defender 365 technology complements our proprietary network defenses, allowing us to reduce threat actor dwell time—which is critical for disrupting attacks before they can become business-disrupting events.

For example:

• Microsoft Defender for Endpoint enables full control for tactical network isolations, provides deep visibility into network connections on an endpoint, and allows analysts to terminate malicious processes or reboot systems

• Microsoft Defender for Office 365 provides tremendous capabilities to combat phishing and business email compromise (BEC) scams, disrupting what has become the number one attack vector

• The combination of Microsoft Azure AD and eSentire’s Atlas XDR platform enables game-changing Identity-based controls, providing the ability to suspend user access to different systems and reduce the impact of compromised credentials

These capabilities are all vital to safeguarding businesses, because as Gartner’s MDR Market Guide notes, “Reducing the time to detect a threat is meaningless without a corresponding reduction in the response time.”

Benefits of eSentire’s MDR with Microsoft 365 Defender Solution Offering

Organizations can take advantage of three key benefits when they engage our MDR with Microsoft 365 Defender service:

• 35% technology cost-savings,

• 50% reduction in total implementation and maintenance costs, and

• 80% reduction in total management costs.

Ultimately, these benefits result in an overall 50% reduction in threat detection and response TCO without compromising on results.

In Conclusion

We’re excited to bring industry-leading MDR capabilities to organizations that have already made significant investments in the Microsoft ecosystem.
