About the Cisco S170 Cisco Email Security Appliance (ESA)
The Cisco S170 Email Security Appliance (ESA) delivers comprehensive threat protection with integrated anti-spam, anti-virus, outbreak filtering, and data loss prevention—all included in the platform, with no additional licensing required for core security functions. Built on Cisco AsyncOS for Email and powered by Cisco's IronPort anti-spam engine, Talos real-time threat intelligence, and SenderBase reputation data, the S170 provides zero-day threat quarantine through global outbreak filters and correlates malicious activity across Cisco's threat network to stop emerging threats before they reach your inbox.
This 1U rack-mount appliance operates as an inline SMTP gateway, handling both inbound and outbound SMTP/ESMTP traffic with integrated TLS encryption and Cisco Email Encryption for message-level protection. Dual anti-virus scanning engines from Sophos and McAfee, combined with RSA Email DLP content scanning for outbound messages, ensure comprehensive threat detection and compliance enforcement. The S170 integrates seamlessly with Active Directory and LDAP for recipient validation and group policy enforcement, while its web-based GUI, CLI (SSH), and SNMP monitoring provide flexible management. Centralized control is available through compatibility with the Cisco Security Management Appliance (SMA), and built-in real-time and historical reporting enables full email traffic visibility and audit compliance—ideal for network engineers and IT procurement teams protecting small-to-medium enterprise environments.
Typical Deployment Scenarios
- Inline MX record gateway protecting all inbound and outbound SMTP traffic with real-time threat correlation via Talos intelligence
- Explicit routing deployment for organizations requiring granular control over email flow and advanced DLP policy enforcement
- Centralized security hub integrated with Cisco Security Management Appliance (SMA) for multi-site email threat visibility and management
- Compliance-focused environments requiring full email audit logging, encryption, and RSA DLP scanning for regulatory requirements
- Organizations consolidating anti-spam, anti-virus, encryption, and DLP functions into a single 1U appliance to reduce operational complexity
