Cisco ISR 4000 Licenits SL-4330-SEC-K9

The Cisco SL-4330-SEC-K9 is a Security license for the ISR 4331 router in the Cisco ISR 4000 series. It unlocks the advanced IOS-XE security capabilities on this mid-range model: hardware-accelerated IPsec, DMVPN and FlexVPN, Zone-Based Firewall, integrated IPS, and support for leading cryptographic algorithms.

Designed for subsidiaries or regional nodes of multi-site organizations requiring strict traffic segmentation and systematic WAN link encryption, the SL-4330-SEC-K9 fits into Cisco SD-WAN deployments or hybrid MPLS architectures. It reduces the need for separate security appliances. Genuine Cisco license, manufacturer warranty.
