Key Benefits Across the 4200 Series
Crypto Acceleration
Dedicated hardware crypto accelerator delivers high-speed TLS decryption without impacting firewall throughput — closing blind spots in encrypted data center traffic.
AI-Powered Policy
Cisco AI Assistant automates policy creation, identifies unused rules, and generates compliance reports using natural language queries from the management console.
Clustering to 16 Nodes
Scale security capacity on demand by clustering up to 16 appliances. Achieve terabits of aggregate throughput with seamless failover and load balancing.
SD-WAN Capable
Integrate SD-WAN connectivity directly into the firewall platform, eliminating the need for separate routing appliances at data center and campus edge locations.
Frequently Asked Questions
The Cisco Secure Firewall 4200 Series is a family of three high-performance firewalls (4215, 4225, 4245) designed for data center, large enterprise, and service provider environments. They deliver 65–140 Gbps of firewall throughput in a compact 1RU form factor with hardware-accelerated encrypted traffic visibility, 16-node clustering, and AI-powered policy management.
The 4215 is ideal for enterprise campus and Internet edge deployments needing up to 65 Gbps throughput. The 4225 serves data center environments at 80 Gbps with higher session capacity and VPN throughput. The 4245 targets service providers and the largest enterprise data centers with 140 Gbps throughput, 60M concurrent sessions, and 25G SFP28 interfaces.
All 4200 Series models support clustering up to 16 nodes, combining multiple firewalls into a single logical device. This enables terabits of aggregate throughput with seamless load balancing and high availability across nodes. You can scale security capacity on demand without replacing hardware as your network grows.
The Encrypted Visibility Engine uses machine learning to identify applications and detect threats in encrypted TLS 1.3 and QUIC traffic without decryption. Combined with the 4200 Series dedicated crypto accelerator hardware, it delivers high-speed TLS decryption when needed without impacting firewall throughput, closing blind spots in encrypted data center traffic.
Yes. The 4200 Series supports Cisco Defense Orchestrator for cloud-based policy management across multiple devices, Cisco Secure Firewall Management Center for centralized on-premises management of large deployments, and Firewall Device Manager for simple local single-device administration. The AI Assistant is available across management platforms for natural language policy queries.
Yes. The 4200 Series integrates SD-WAN connectivity directly into the firewall platform, eliminating the need for separate routing appliances at data center and campus edge locations. This converges security and networking into a single device, simplifying architecture and reducing operational overhead.
