Cisco Secure Email

Cisco Secure Email is an enterprise email security platform engineered to defend cloud and on-premises mailboxes against sophisticated cyber threats, including business email compromise, spear-phishing, credential harvesting, malware, and ransomware. Operating across inbound, outbound, and internal message streams, the platform leverages multi-layered threat intelligence from Cisco Talos to analyze sender reputations, inspect URL redirects, and detect zero-day malicious attachments before they reach end-user inboxes. Key technical capabilities include machine-learning behavioral analysis, graymail management, domain-based message authentication (DMARC, DKIM, SPF), and automated message remediation to remove malicious emails retrospectively from Microsoft 365 or Exchange environments.

The solution supports diverse deployment architectures, available as a cloud-delivered gateway service, virtual appliance, hardware appliance, or cloud-native API integration via Cloud Mailbox Defense. It interfaces natively with Cisco SecureX, Cisco Secure Endpoint, Cisco Identity Services Engine, and enterprise SIEM/SOAR platforms to provide unified threat correlation and rapid automated containment. Integrated data loss prevention and end-to-end message encryption allow organizations to protect sensitive financial records and customer data while complying with privacy mandates.

Primary enterprise use cases include stopping advanced phishing campaigns, preventing executive impersonation, securing corporate communication pipelines, and enforcing regulatory data protection standards across global distributed workforces.
