Cisco Email Security (IronPort)

Cisco Email Security (formerly IronPort) is a robust gateway solution that blocks spam, malware, and advanced threats at the network edge. Using reputation filtering, dynamic analysis, and advanced phishing detection, it inspects incoming/outgoing emails in real time. A policy engine lets admins set encryption requirements or DLP rules for sensitive data. The system integrates with Cisco Talos intelligence for global threat updates. Reporting dashboards show top spam sources, blocked viruses, and user-level metrics. Though typically used by larger organizations, small businesses in high-risk sectors can deploy Cisco on-prem or in the cloud.
