Cisco Secure Email Threat Defense
Mid-market and enterprise teams defending Microsoft 365 should choose Cisco Secure Email Threat Defense for its ability to hunt and remediate threats across your entire email history in real time, not just block at the gateway. The searchable threat telemetry and post-breach remediation capabilities address a real gap in most email platforms, which stop at detection and leave you manually digging through logs. Skip this if your organization runs heavy on Gmail or other non-Microsoft email infrastructure, or if you need advanced user behavior analytics layered on top of threat detection.
Egress Intelligent Email Security
Mid-market and enterprise teams struggling with user-driven breaches will find real value in Egress Intelligent Email Security's human risk scoring and adaptive controls, which flag risky behavior before compromise happens rather than just blocking known threats. The platform's NIST coverage in Continuous Monitoring and Adverse Event Analysis reflects its strength in detecting anomalies tied to individual user patterns; combined with native Microsoft 365 integration, deployment friction drops significantly. Skip this if your priority is post-breach response and forensics; Egress optimizes for prevention and user behavior correction, not investigation infrastructure.
