Enabling OT with Cyber-Physical Protection

Through our software-enabled hardware platforms, we enable secure and reliable operations, protecting against both today’s cybersecurity challenges and those yet to come.

As cyberattacks on critical infrastructure are on the rise, software alone is not able to deliver sufficient protection. Waterfall’s unidirectional technology uses an innovative approach, combining unique hardware paired with dedicated software that provides industrial systems with dedicated protection while still allowing remote visibility and remote access.

Attackers are physically restricted with a hardware enforced barrier that stops OT cyberattacks and shields industrial controls from any outside attempts to plant malicious code or any other harmful activity.

Benefits

Unbeatable OT Protection

Hardware-enforced gateways prevent any inbound cyberattack by allowing data to flow strictly one way from OT to IT networks.

Seamless IT/OT Integration

Replicate OT data securely to enterprise systems in real time—without ever connecting the networks bidirectionally.

Safe Remote Access

Enable remote monitoring and data access to OT devices while maintaining complete network segregation.

Cloud Compatibility

Connect OT systems to industrial cloud services securely, without exposing your network to incoming threats.

Centralized Asset Management

Monitor multiple unidirectional gateways across sites using a unified dashboard integrated with your SIEM tools.

Minimal Maintenance Overhead

Once installed, the system is effectively “set‑and‑forget,” delivering continuous protection without ongoing administration.

Compliance Made Easier

Reduces the complexity of meeting standards like NIST, ISA/IEC 62443, NERC CIP, and more by enforcing physical segmentation.

Scalable & Flexible Deployment

Supports various industrial protocols, devices, and environments, ideal for sectors like energy, water, rail, manufacturing, and beyond.
