The Cisco Firepower 4100 Series is a family of high-performance, modular
next-generation firewall (NGFW) appliances designed for enterprise data centers, service providers,
and large campus environments. These platforms deliver advanced threat protection, deep traffic
inspection, and scalable performance while maintaining a compact 1RU footprint.
The series includes four models: FPR-4112, FPR-4115, FPR-4125, and FPR-4145,
each offering different throughput and scalability options.
