Cisco ASA5525-K8 ASA 5525-X 1U DES Encryption Hardware Firewall

The K8 order is the DES firewall edition

ASA5525-K8 is the Cisco ASA 5525-X Firewall Edition ordered with DES licensing. Cisco lists eight copper Gigabit Ethernet data ports, one separate copper Gigabit management port and one AC supply for this order. Keep K8 distinct from K9: the latter is the 3DES/AES order, and the product name alone does not establish an encryption upgrade on the supplied unit.

Separate interface capacity from added hardware

The eight listed data interfaces do not include the separate management interface. Confirm the installed interface options and the AC supply against the quotation. The base ASA5525-K8 identifier is also different from the DC, IPS and SSD120 variants; it does not establish that their power configuration, inspection service or storage option is supplied.

Verify licensed operating modes before migration

The official ordering row lists 750 IPsec VPN peers and two included security contexts, together with Active/Active high-availability capability. These are platform and license features, not proof of an active two-appliance deployment or present-day remote-access subscription rights. Check the installed activation state, operating mode and peer appliance before moving a production configuration.

Plan around a support date that has already passed

Cisco explicitly includes ASA5525-K8 in EOL13130 for the ASA5525, ASA5545 and ASA5555 appliances. The final hardware support date was September 30, 2025. Treat this as legacy replacement equipment and assess the required software, cryptographic compatibility and migration path before ordering. A reseller warranty or the listed condition does not extend that Cisco lifecycle milestone.
