Cisco Industrial Threat Defense OT cybersecurity solution

From OT visibility to zero trust segmentation to advanced detection, get a comprehensive platform that unifies IT and OT cybersecurity.

Uncover your industrial cybersecurity posture

Easily inventory your OT/ICS assets and their behaviors with solutions that use your network as a sensor to provide full visibility at scale—and the insights you need to reduce the attack surface.

Control and secure OT remote access

With easy-to-use, cloud-delivered secure remote access built into our network equipment, you avoid shadow IT—and your OT teams can manage industrial assets from anywhere.

Protect operations

Enforce ISA/IEC62443 zones and conduits and prevent threats from spreading. Use your network as the enforcer to easily implement a zero-trust microsegmentation strategy.

Find and block threats across IT and OT

With OT insights in your IT security tools, you can detect, investigate, and resolve threats across IT and OT—all from a single console.

Build your own industrial cybersecurity journey
