Innovative OT Security Solutions by Cisco at RSAC 2025

The world’s cybersecurity community is gearing up to meet at the RSAC™ 2025 Conference in San Francisco. I’m looking forward to reconnecting with old friends, making new ones, and discussing OT security needs with industrial organizations. Be sure you stop by the Cisco booth and say Hi! We’ll be showcasing the latest features of Industrial Threat Defense, Cisco’s comprehensive and highly modular OT security solution. It uses the industrial network as the fabric to easily…

Cisco Industrial Security: Your blueprint for securing critical infrastructure

Safeguarding industrial control systems (ICS) from cyber threats is a critical priority, but transforming these intentions into effective actions can be challenging. Given the complexity of ICS and their networks, which often rely on outdated technologies and inadequate security measures, it can be difficult to determine the best starting point. Cisco Validated Designs (CVDs) are proven networking and security reference architectures that industrial organizations can use to build advanced capabilities and create a flexible foundation…

Fusing Security Into the Network Fabric: From Hybrid Mesh Firewalls to Universal ZTNA

If you’ve heard it once, you’ve probably heard it a million times: “today’s enterprise environments are becoming more and more complex.” I know it’s something I’ve been known to say a time or two (or a million). Here’s the thing: it’s true. There are several factors at play, but two of the biggest are the increasingly fine-grained composition and distribution of applications along with an increasingly distributed and mobile workforce. Then, while the rise of…

Cisco and Rockwell strengthen OT/ICS security with visibility for converged plantwide ethernet (CPwE)

The turtle, protected by its hard shell, is a good metaphor for the security model used in most industrial networks. The industrial DMZ (iDMZ) is the shell that protects the soft, vulnerable center—the industrial control systems (ICS) the business depends on. But while the iDMZ blocks most threats, some will inevitably slip through. When they do, they can move sideways from device to device, potentially causing downtime and information leakage. Giving traffic free rein once…
