Infrastructure is evolving fast. AI workloads are scaling rapidly. Encrypted traffic is now the norm. Applications are distributed across data centers, cloud, and edge. Across enterprise, hyperscale, neocloud, and telecom environments, one thing is clear: performance expectations are rising—and security has to keep up.
In our previous blog, we introduced the Cisco Secure Firewall 6100 Series and how it helps to redefine security and speed for high-performance AI-ready data centers. As organizations move from planning to real deployments, the conversation is shifting: How do you scale security as fast as your infrastructure—without slowing things down or driving up costs?
When Growth Creates New Challenges
No matter the environment, customers are running into similar issues.
- In enterprise data centers, it’s about securing east-west traffic across AI workloads without introducing latency.
- For hyperscalers and neocloud providers, it’s maximizing performance within tight space and power constraints.
- In service provider and telco networks, it’s scaling security for 5G traffic and massive volumes of encrypted connections.
Across all of them, one pattern shows up quickly: Security becomes the bottleneck at scale.
Rethinking What “Performance” Really Means
It’s no longer just about peak throughput. Customers are asking:
- Can it scale as fast as my environment?
- How much space and power will it consume?
- How does the cost grow as I expand?
That’s the lens the Cisco Secure Firewall 6100 Series was built for. To answer these questions, we had to look under the hood. We fundamentally re-architected our data plane software, optimizing how CPU sockets and individual core slices communicate. By eliminating cross-socket micro-latencies, we unlocked true line-rate performance in a fraction of the traditional hardware footprint.
What This Looks Like in Practice
A Step-Change in Efficiency
By moving away from power-hungry, multi-slot chassis, a single 2RU 6100 Series appliance delivers up to 600 Gbps of NGFW throughput and 550 Gbps of IPsec VPN throughput. Compared to legacy chassis systems, customers can achieve:
- Up to 80% less space required
- Up to 60% lower power consumption
- Up to 1/3 the cost per protected Gbps
What that means: More usable capacity, lower energy costs, and radically better data center economics.
Flexibility with Pay-As-You-Grow Scaling
Instead of over-provisioning a large chassis on day one, organizations can start with what they need and scale as demand grows. With modular N+1 clustering (supporting up to 16 nodes), the 6100 Series scales to up to 8 Tbps of L7 throughput. You can add capacity incrementally without ripping and replacing hardware.
What that means: No large upfront investments. Capacity is aligned to actual demand, optimizing your footprint, power, and cooling over time.
No Trade-Offs Required
- Encrypted Visibility at Scale: Using our AI-driven Encrypted Visibility Engine (EVE), the 6100 Series identifies threats in encrypted traffic without decryption, preserving privacy and line-rate speed. For deep inspection, dedicated hardware crypto offload delivers up to 150 Gbps of TLS decryption.
- Zero-day threat protection: On-box machine learning (Snort ML) stops evasive threats in real-time.
What that means: You don’t have to choose between speed and security anymore—you get both.
Built for the Environments You Run Today
The 6100 Series is designed for how modern infrastructure operates:
- Enterprise data centers: Secure AI-driven east-west traffic and enforce segmentation—without impacting performance.
- Hyperscale and neocloud: Maximize performance density while minimizing footprint and power.
- Service provider and telco: Scale Gi-LAN, roaming, and security gateway (SEG) functions for 5G growth.
Extending Security Across Hybrid Environments
Of course, infrastructure doesn’t stop at the data center. Applications span cloud, edge, and on-prem environments—and security needs to be consistent across all of them. That’s where the Cisco Hybrid Mesh Firewall comes in:
- Define policy once, enforce it everywhere.
- Distribute security closer to workloads.
- Manage it all through Cisco Security Cloud Control.
Within this architecture, the 6100 Series provides a high-performance backbone, delivering the scale needed for the most demanding environments.
Securing What Comes Next
AI, cloud, and 5G aren’t slowing down—and neither can security. Organizations need solutions that scale to terabit-level performance, operate efficiently within real-world constraints, and extend seamlessly across hybrid environments.
The Cisco Secure Firewall 6100 Series—combined with Hybrid Mesh Firewall—is built for exactly that. Because at this scale, security shouldn’t hold you back—it should help you move faster.
