Cisco FPR-4115-K9 End of Life & End of Support

Cisco Firepower 4115 Security Appliance

Supported through Jan 31, 2031

The second generation Firepower 4100 Series, the 4112, 4115, 4125 and 4145, succeeded the original 4110/4120/4140/4150 chassis and became Cisco's mainstream data center NGFW platform through the early 2020s. Cisco's amended bulletin closes out the whole line with end of sale on January 6, 2026, and names the Secure Firewall 4200 Series as the direct replacement. Support continues through January 31, 2031, giving installed customers a long runway to plan the move.
