DTEX and Microsoft O365 E5: The Partner Opportunity

Organizations using Microsoft Office 365 E5 (also referred to as Microsoft O365 E5) are investing in one of the most powerful enterprise security platforms available today. When paired with DTEX, this investment extends even further — unlocking new levels of visibility, insider threat detection, and risk-adaptive data loss prevention (DLP).

DTEX complements Microsoft by correlating unique alerts across the Microsoft ecosystem into a holistic risk score, surfacing early indicators of insider threat activity. By analyzing human behavior at the very start of the Insider Threat Kill Chain, organizations can identify risks and intervene before they escalate into serious security incidents.

This blog explores how DTEX enhances Microsoft 365 E5 — showing how the two together deliver faster time to value and stronger insider risk protection.

DTEX and Microsoft Defender: Advanced endpoint context

Microsoft Defender for Endpoint provides strong malware detection and device-level insights. However, it is not designed to capture the full sequence of human behaviors surrounding an incident.

DTEX fills this gap by acting as a lightweight “flight recorder” across every endpoint. It provides contextual detail on what happened before, during, and after a malware event — helping analysts move from simply detecting malware to understanding root cause attribution and user intent.

Together, Microsoft Defender and DTEX empower security teams with enriched context mapped against frameworks like MITRE ATT&CK, enabling faster, more confident incident response.

DTEX and Microsoft Information Protection and Governance: Beyond traditional DLP

Microsoft Information Protection and Governance equips enterprises with essential classification capabilities and traditional DLP controls. These are effective for alerting on accidental or negligent insider risks.

DTEX extends this foundation by analyzing data lineage — capturing who created, modified, or aggregated files, how they were used, and whether unusual patterns of access suggest malicious intent. This additional context provides early warning signals of insider threat activity, particularly around intellectual property (IP) such as source code or design documentation that often falls outside regulated data classifications.

The integration of Microsoft Information Protection and Governance with DTEX ensures organizations can detect both negligent and malicious insider risks while maintaining user privacy.

DTEX and Microsoft Defender for Cloud Apps: SaaS visibility

Microsoft Defender for Cloud Apps delivers strong visibility and governance for sanctioned SaaS and cloud applications.

DTEX extends this by continuously profiling endpoint access to both sanctioned and unsanctioned SaaS services in real time, without additional configuration. By monitoring uploads, anomalous user behavior, and peer group deviations across Windows, macOS, Linux, Citrix, VMware, and cloud environments (e.g., AWS Workspaces), DTEX closes gaps where insiders might otherwise exfiltrate sensitive data.

Together, Defender for Cloud Apps and DTEX provide comprehensive coverage of SaaS misuse and insider threat detection.

DTEX and Microsoft Sentinel: SOC enrichment

A critical advantage of the DTEX-Microsoft integration is the ability for DTEX alerts and telemetry to flow into Microsoft Sentinel. By combining Microsoft’s rich set of IOCs with DTEX’s behavioral intelligence, SOC teams can correlate user activity, data lineage, and endpoint telemetry into a single source of truth.

This enrichment accelerates investigations, eliminates false positives, and helps analysts prioritize real risks over noise.

Why DTEX and Microsoft are better together

On their own, Microsoft 365 E5 security modules provide world-class protection for regulated data and common cyber threats. But when integrated with DTEX, organizations gain:

• Deeper visibility into human behaviors driving data movement
• Risk-adaptive DLP that goes beyond static rules to detect intent
• Early insider threat detection, covering both negligent and malicious actors
• SOC enrichment, accelerating investigations and reducing analyst burden
• Privacy-preserving telemetry, balancing trust with security

This “better together” story creates a powerful value proposition for enterprises — and a unique opportunity for partners to deliver more outcomes to Microsoft clients.

DTEX and Microsoft 365 E5: Customer perspective

Customers consistently report that while Microsoft 365 E5 offers the right foundation for classification and compliance, DTEX provides the depth needed to stay ahead of sophisticated insiders.

A CISO of a leading financial institution noted:

“We have found Microsoft 365 E5’s Information Protection and Governance tools match those offered by best of breed pure cybersecurity vendors. As a Microsoft shop, these tools offer us the foundation we need to identify and classify our structured, regulatory mandated data accurately and effectively. DTEX pushes our visibility deeper and wider, giving us the ability to proactively monitor data usage including unstructured data and IP in the context of human activity, and to pre-empt suspicious behavior sequences before a possible breach.”
