What happened
Proofpoint announced that its Core Email Protection API has been added to the Microsoft Defender for Office 365 Integrated Cloud Email Security (ICES) vendor ecosystem. The integration surfaces Proofpoint’s AI‑driven detections—phishing, business‑email‑compromise, ransomware—directly within the Microsoft Defender console. This unified view reduces context‑switching for analysts, accelerates investigations, and reinforces a layered defense‑in‑depth posture for Microsoft 365 customers worldwide.
Why it matters for trust and compliance
- Unified detection visibility satisfies the control objective of consolidated monitoring and incident response, a single control that maps to many compliance frameworks.
- Provides continuous, auditable evidence of email‑threat detections across two vendors.
- Enables mapping of integrated alerts to a single control objective, simplifying audit readiness.
Who is affected
Enterprises using Microsoft 365 for email Managed service providers delivering Microsoft‑based security
Recommended actions
- Map existing email‑security detections to the integrated monitoring control objective.
- Enable the Proofpoint‑Microsoft Defender integration and capture unified logs for audit evidence.
- Update SOC playbooks to incorporate the combined alert feed and test response times.
