Cisco Cloud DDoS-500 Addtl Protected Networks Fixed SMS-1K adds licensing for additional protected networks, giving security teams a straightforward way to extend cloud DDoS coverage as environments grow. This add-on is built for organizations that need to protect more than a single network segment while keeping procurement and administration predictable.
