Cisco’s New Secure Firewall Offers a New Architecture Designed for Hybrid Working


Cisco Systems Inc. today announced the Secure Firewall 3100 Series, a versatile midrange firewall appliance featuring a new architecture designed expressly for hybrid working.

The Secure Firewall 3100 Series offers high performance and flexibility to enable hybrid workers as well as firewall administrators, who can now manage their cloud and hybrid firewalls from anywhere in the world.

The 3100 Series provides visibility and enforcement designed to prevent the network from going under and reinforce a zero-trust security posture. Cisco touts the new product as delivering efficiency and simplicity through advanced automation and integrations that drive cost savings for modern environments.

Encryption is at the heart of the new Secure Firewall 3100 Series architecture, which emphasizes processing encrypted traffic.

Cisco says the traditional industry approach has been to deploy a research cryptographic accelerator that works in tandem with the x86 processor to process IPsec and Transport Layer Security traffic for VPN inspection and transit. . This approach is said to cause considerable performance degradation because the nature of side-seeking requires multiple traversals of the shared system bus for each encrypted or decrypted packet.

Instead, the Secure Firewall 3100 Series appliances offer an all-new, field-programmable gated network component between the internal switch fabric and the x86 processor complex. This not only implements a next-generation stream offload engine for ultra-fast single-stream throughput and high-performance computing-grade latency, but it also provides cryptographic acceleration capability along the way. This intermediate component can decrypt and encrypt these streams in hardware without relying on the main system bus or consuming valuable x86 CPU cycles, providing much greater speed.

“Hybrid working is the most transformative workforce trend in a generation,” Jeetu Patel, executive vice president and general manager of Cisco Security and Collaboration, told SiliconANGLE. “Success requires highly integrated, immersive, and interoperable hardware and software experiences that support all forms of collaboration to meet people’s expectations for flexibility, seamless engagement, and inclusiveness, whether they’re in the office , remote or anywhere in between.

Patel added that “as our employees work from anywhere on any device, accessing apps and data from anywhere, security is more fundamental than ever. Companies that don’t prioritize people and that don’t offer the flexibility of hybrid working will struggle to attract and retain talent.”
