The flagship of the 4200 Series, the 4245 delivers 140 Gbps of symmetrical firewall, IPS, and VPN throughput in a compact 1RU chassis. Purpose-built for service providers and the largest enterprise data centers, it features hardware-accelerated crypto, 16-node clustering, and up to 34 independent firewall instances for maximum multi-tenant density.
The 4245 delivers 140 Gbps across firewall, IPS, and VPN — symmetrical performance that eliminates the trade-offs between enabling security features and maintaining throughput in the most demanding service provider and data center environments.
A dedicated crypto accelerator offloads TLS decryption from the main processing pipeline, delivering 45 Gbps of decryption throughput without impacting firewall or IPS performance. See threats hiding in encrypted traffic at service provider scale.
Scale security capacity on demand by clustering up to 16 appliances together. Achieve terabits of aggregate throughput with seamless failover and load balancing across all cluster members.
Run up to 34 independent firewall instances on a single 4245 appliance. Each instance operates with its own policies, interfaces, and management — the highest multi-tenant density in the 4200 Series.
Machine learning-based detection engine identifies and blocks zero-day exploits inline. The Encrypted Visibility Engine detects threats in TLS 1.3 and QUIC traffic without decryption, powered by Cisco Talos intelligence.
Manage from Cisco Security Cloud Control for centralized cloud operations, Firewall Management Center (FMC) for on-premises control, or Firewall Device Manager (FDM) for local administration.
