Cisco Security License for ISR 1100 4P Series

Add the security software entitlement designed for the Cisco ISR 1100 4P Series and keep branch protection aligned with the router already in service. This license activates Cisco IOS Security capabilities for a single router, giving infrastructure teams a clear path to extend security functions without replacing the platform. For organizations that standardize on Cisco at the edge, licensing matters as much as hardware. The right entitlement keeps procurement clean, support aligned, and deployment predictable. This security license is built for that model: one router, one software right, one controlled path to enabling the security features associated with the ISR 1100 4P Series. It is a practical choice when the goal is to protect branch traffic, maintain consistency across Cisco-managed sites, and avoid unnecessary platform changes. Compared with lower-tier alternatives that leave capability gaps, this license helps ensure the router can be deployed with the security posture the site requires.
