Why Organizations Choose the 6100 Series

Purpose-built for the highest-performance data center and service provider environments where terabit-scale threat inspection is a requirement.

Terabit-Scale Threat Inspection

Inspect up to 8 Tbps of traffic with line-rate threat protection. Hardware crypto offload handles encrypted traffic inspection at data center scale without performance degradation.

80% Less Space, 60% Less Power

Consolidate your data center security infrastructure with a 2RU chassis that replaces multiple racks of legacy firewalls while reducing power consumption by more than half.

Built-In Zero-Day Protection

SnortML machine learning engine and Encrypted Visibility Engine work together to detect and block threats in encrypted traffic — without decryption or signature updates.

Carrier-Grade Security

Purpose-built for service providers, 5G infrastructure, and large-scale data centers requiring the highest throughput and lowest latency.

Frequently Asked Questions

The Cisco Secure Firewall 6100 Series is a family of high-performance data center firewalls designed for the most demanding environments. Available in two models — the 6160 and 6170 — the series delivers up to 635 Gbps of NGFW throughput and up to 8 Tbps of aggregate threat inspection when clustered. It is purpose-built for large enterprise data centers, service providers, and AI-ready infrastructure.

The 6170 is the higher-performance model, offering 635 Gbps NGFW throughput (vs. 520 Gbps on the 6160), 150 Gbps TLS decryption (vs. 100 Gbps), 105 million concurrent sessions (vs. 75 million), and 2x 7.2TB storage (vs. 2x 3.6TB). Both models share the same 2RU chassis, interfaces, and clustering capabilities. The 6160 is ideal for large data centers, while the 6170 targets service providers and AI-scale workloads.

The 6100 Series supports clustering of up to 4 units (with 16-unit clustering planned for a future release). Clustering allows multiple appliances to operate as a single logical firewall, providing seamless load balancing, failover, and aggregate throughput measured in terabits per second. This makes it possible to scale security capacity without redesigning your network architecture.

Yes. The 6100 Series includes a dedicated hardware crypto accelerator that delivers 100–150 Gbps of TLS decryption throughput without impacting firewall performance. Additionally, the Encrypted Visibility Engine uses AI-powered analysis to detect threats inside encrypted TLS 1.3 and QUIC traffic without requiring decryption, preserving both security and user privacy.

The 6100 Series delivers 5x better price-performance than comparable data center firewalls while using 80% less rack space and 60% less power. Its compact 2RU chassis replaces multiple racks of legacy appliances, and clustering eliminates the need for oversized individual units. This translates directly to lower capital costs, reduced power and cooling expenses, and more efficient use of data center real estate.

The 6100 Series can be managed through Cisco Security Cloud Control (cloud-based), Firewall Management Center (on-premises), or Cisco Defense Orchestrator for multi-device policy management. All options include the Cisco AI Assistant, which uses natural language to help create policies, identify unused rules, and generate compliance reports.
