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.
