Data Center Security in a 1RU Form Factor

65 Gbps Firewall Throughput

The 4215 delivers 65 Gbps of NGFW throughput (FW + AVC) with full IPS active — providing the performance headroom that enterprise campus and Internet edge environments demand as encrypted traffic volumes continue to grow.

Hardware Crypto Acceleration

A dedicated crypto accelerator offloads TLS decryption from the main processing pipeline, delivering 20 Gbps of decryption throughput without impacting firewall or IPS performance. See threats hiding in encrypted traffic at scale.

16-Node Clustering

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.

Multi-Instance Support

Run up to 10 independent firewall instances on a single 4215 appliance. Each instance operates with its own policies, interfaces, and management — ideal for multi-tenant and segmented environments.

SnortML Zero-Day Protection

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.

Flexible Management

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.

Features and Benefits

Built for High-Performance Data Center Security

The Firewall 4215 runs the same Threat Defense software as Cisco’s largest firewalls, giving data center administrators access to the full Cisco security platform with enterprise-class throughput and density.

SnortML Zero-Day Detection

Machine-learning detection engine blocks zero-day exploit patterns inline — trained on Cisco Talos threat data from 193 countries. Protects against threats before signatures are available.

Encrypted Visibility Engine

Detect and block threats in encrypted traffic without decryption overhead. EVE uses AI-assisted behavioral fingerprinting to identify malicious applications hiding in TLS 1.3 and QUIC sessions.

Cisco AI Assistant

Automate policy creation, identify unused rules, and generate compliance reports using natural language queries — available in both cloud-delivered and on-premises management options.

Cisco Talos Threat Intelligence

Backed by one of the world’s largest commercial threat intelligence organizations, analyzing 900 billion security events daily to keep your data center defenses current.

Hardware Root of Trust

Built with Cisco Trustworthy Technologies including a hardware root of trust, cryptographically signed software image validation, and anti-tamper protections for supply chain security.

Active/Standby High Availability

Maintain data center connectivity during planned maintenance or hardware failure with Active/Standby HA pairs, ensuring business continuity for your critical workloads.
