Cisco ASA 5505 Security Plus License L-ASA5505-SEC-PL= | HA, DMZ, VLAN — L-ASA5505-SEC-PL=

Unlock advanced capabilities on Cisco ASA 5505 with the Security Plus license. Built for environments that need more than baseline firewall functionality, it adds high availability support, DMZ capability, VLAN trunking, and expanded connection capacity to an existing ASA 5505 deployment. For infrastructure teams, this license matters because it turns a compact security appliance into a more capable edge platform. High availability helps support continuity planning. DMZ support enables cleaner separation of public-facing services. VLAN trunking improves segmentation across connected networks. Additional connection capacity gives the firewall more room to handle growing traffic and device counts. This is the kind of upgrade that makes sense when the hardware is already in place and the network design is evolving. Instead of replacing the firewall, Security Plus extends what the ASA 5505 can do, helping organizations preserve their investment while meeting stricter operational and security requirements. It is a practical choice for branch offices, distributed sites, and smaller enterprise segments that still need disciplined control.
