Securing Email with Cisco Email Security Appliance (SESA)

Email infrastructure is one of the most frequently exploited entry points for cyberattacks. The SESA course shows you how the Cisco Email Security Appliance identifies, classifies, and stops inbound threats – reliably, before any damage occurs.

Key topics

  • Detecting threat profiles early using AI-powered analysis methods.
  • Categorizing attack vectors by severity and initiating targeted countermeasures.
  • Maintaining and evaluating security policies and reports in an automated way.
  • Implementing robust protection against spam, phishing, and malware.
  • Operating stable email flows securely even in complex network architectures.

Prerequisite
A basic understanding of email protocols and network security makes getting started easier – an IT background is helpful but not strictly required.

Target group
Suited for administrators, security specialists, and IT analysts who integrate email security into their area of responsibility.

Those who master SESA can secure email communications systematically – and are equipped to respond to new threat scenarios in a structured and well-founded way.
