Apply web-security policy to enterprise web traffic with a dedicated Cisco Secure Web Appliance hardware platform. The S698 is intended for deployments where outbound web access needs centralized controls rather than relying solely on endpoint-level enforcement. It provides the appliance foundation for Cisco web-security services that govern how users and systems reach internet resources. A secure web gateway deployment places policy enforcement between internal users and the web. This approach supports consistent treatment of browsing activity across office, campus, and data-center-connected users whose traffic is directed through the gateway. Web-access rules, URL-based controls, web reputation checks, and inspection services can be administered through the Cisco Secure Web Appliance environment when the relevant services are enabled. WSA-S698-K9 identifies the S698 hardware ordering configuration. Select this appliance when the deployment calls for the S698 model specifically, rather than treating all Cisco Secure Web Appliance platforms as interchangeable. Confirm the required traffic-handling architecture, software release, entitlement set, and network insertion method against the environment before installation. The appliance is a network security platform, not an endpoint agent or a cloud-only web-security subscription.
