What is Cisco Secure Email?

Cisco Secure Email (formerly Cisco Email Security Appliance / IronPort) is an enterprise email security gateway that provides protection against phishing, malware, ransomware, and business email compromise. As part of Cisco's broader security portfolio, it integrates with Cisco SecureX, Talos threat intelligence, and Cisco's network security products to provide cross-domain threat visibility. Cisco Secure Email is available as a cloud-hosted service or on-premises appliance and is particularly strong in organizations that have standardized on Cisco networking and security infrastructure.
