Cisco FL-VPERF-4P-100= IPsec Plus 100 Mbps License | ISR 1100 — FL-VPERF-4P-100=

Raise encrypted traffic capacity on Cisco ISR 1100 4P series routers with the IPSEC PLUS 100 MBPS LICENSE. This license is built for environments where branch connectivity, secure tunnels, and predictable VPN performance matter more than generic feature bundles. For infrastructure teams, the advantage is straightforward: you can scale IPsec throughput to 100 Mbps while staying on the ISR platform already deployed at the edge. That helps avoid unnecessary hardware refreshes when the bottleneck is encrypted traffic handling rather than routing capability. This license is a practical fit for organizations that need to protect branch traffic, support remote users, or maintain site-to-site tunnels with clearer performance headroom. It gives procurement and architecture teams a defined capacity step, making it easier to align spend with actual traffic requirements. Compared with lower-capacity options, a 100 Mbps IPsec entitlement is a better fit when security overhead is starting to constrain throughput and the business needs more room without changing the router footprint. Ideal For Branch offices needing higher encrypted VPN throughput Site-to-site tunnels carrying business-critical traffic Remote access environments with growing IPsec demand Cisco ISR 1100 4P deployments requiring a capacity step-up Why This Product 1 100 Mbps throughput tier for encrypted traffic 2 License upgrade instead of router replacement 3 Built for Cisco ISR 1100 4P series 4 Better fit for growing VPN demand than lower tiers
