Place web-security inspection and access control at a defined network point with Cisco Secure Web Appliance S198 hardware. This appliance is intended for organizations that direct user web traffic through an on-premises control point before it reaches the internet. It provides a dedicated platform for applying web-use policies and security inspection without assigning that role to a general-purpose server. A Secure Web Appliance deployment commonly sits between internal users and the internet, where it can apply organization-defined rules to web requests and responses. Network and security teams can use this appliance role when they need centralized control of browsing activity, policy enforcement, and visibility around outbound web access. Its appliance form keeps the web-security function separate from routing, switching, and endpoint workloads. WSA-S198-K9 identifies the Cisco S198 appliance ordering configuration. The S198 designation matters when matching an existing Cisco Secure Web Appliance environment or defining a hardware refresh for an established web-security architecture. Select it for deployments requiring dedicated web-security appliance hardware, then align traffic handling, policy configuration, and any required service entitlements with the organization’s Cisco security design.
