As outlined in our recent blog, Rethink your switch refresh, today’s switch decisions carry long-term implications. With many Cisco platforms approaching end-of-life and the demands on modern networks rapidly changing, a like-for-like replacement may no longer be enough. Instead, organisations need to align their refresh strategy with the specific challenges they face, and we will explore three common scenarios in a short blog series to guide you.
In this blog, we focus on security and how the switches you select today will enhance or diminish your ability to effectively enforce security policies in the future.
This is where Cisco’s new generation of Smart Switches comes into play. They aren’t just marketing labels; they enable a fundamentally different security posture. With the right infrastructure in place, security moves closer to the edge of the network, closer to the workload, and closer to where it’s needed most.
Modern environments rarely operate within clear perimeters. With hybrid deployments, containerised applications, IoT/OT environments and dev environments, the challenge of securing east-west traffic without complex micro-segmentation is growing.
In many organisations, the development of security policy still depends heavily on traditional firewalls or central enforcement points. The result is challenges with scalability, fragmented visibility and delayed response, especially in environments where workloads shift dynamically and are created ad hoc.
Cisco Smart Switches are an essential part of the Cisco Hypershield security architecture, designed to deliver next-generation network security through a hybrid approach that merges network-based enforcement with agent-driven protection.
Equipped with integrated Data Processing Unit (DPU) resources, these switches are designed for security at scale. While initial releases focus on Layer 4 security policy enforcement, future software updates will broaden capabilities to include IPSec encryption and NAT/PAT functions, enabling comprehensive in-network security operations.
Cisco Smart Switches already deliver immediate value across critical use cases:
The typical switch refresh cycle lasts five to seven years. Over that time, organisations will face significant shifts in how applications are developed, deployed and secured. A like-for-like replacement might tick the compliance box for today, but it risks leaving your infrastructure unprepared to deal with future threats and what’s to come.
Choosing Smart Switches now allows you to build toward a future where network and security operations are more integrated. It’s about ensuring the network is not just a transport layer, but a security control surface in its own right.
Data#3 can assist in evaluating your current environment and deciding if a security-first refresh aligns with your infrastructure plans. If you’re already dealing with segmentation complexity, limited visibility or outdated enforcement models, request a meeting with the Data#3 team via the form below or contact your Account Manager to arrange a straightforward, expert-led discussion.
