An Integrated Platform for Operational Technology Visibility & Security

We combine visibility from the endpoint to the air with continuous monitoring and AI-powered analysis to increase cyber resilience.

Why Choose an OT & IoT Cybersecurity Solution?

Operational technology environments have unique requirements, and partnering with a vendor who understands them is critical to a successful risk management program.

OT systems prioritize safety and reliability over confidentiality.

Industrial protocols are unknown in the IT world and are inherently insecure.

Patching in OT can’t be automated like in IT.

The volume of OT and IoT devices make them harder to manage than IT devices (billions vs. millions).
