What replaces the ASA5545?
The FPR1150 is a direct replacement for a Cisco ASA 5545-X.
The Cisco ASA 5545-X is now End of Life and Cisco Support for the ASA5545 Adaptive Security Appliance will cease in September 2025, Cisco recommends that Customers with ASA5545-X products migrate to the Firepower 1000 series firewalls.
The direct replacement for the ASA5545 would be the FPR1150 which can be configured as an ASA initially and reimaged as an FPR NGFW as required.
Assuming your ASA5545 is running as an ASA then the transition to the FPR1150 should be straightforward.
If, however, you would like to upgrade from the Layer 4 ASA Firewall to a Layer 7 NGFW then Cisco recommend the FPR1150-NGFW-K9.
Layer 4 is the OSI Transport Layer, where TCP and UDP function.
Layer 7 is the OSI Application Layer, where Apps such as Facebook and Linkdin function – if you want to manage these then you need NGFW.
