Waterfall Security Unidirectional Gateway
The OT Security Company.
Overview
Waterfall Security Solutions is known for its Unidirectional Security Gateways, a hardware-based alternative to firewalls for protecting industrial networks. The gateway transmits information out of an OT network without allowing any data, not even acknowledgements, to flow back in. This physically prevents remote attacks and malware from penetrating the protected network, ensuring operational integrity. They also offer other products for secure remote access and data sharing.
✨ Key Features
- Hardware-enforced Unidirectional Data Flow
- Physical prevention of remote network attacks
- Secure replication of industrial data to IT networks
- Support for numerous industrial protocols and applications
- Compliance with NERC CIP and other standards
🎯 Key Differentiators
- Hardware-enforced physical security, not just software policy
- Eliminates the possibility of inbound, network-based attacks
- Considered the gold standard for high-security industrial environments
Unique Value: Provides physically guaranteed, hardware-enforced protection from remote network attacks, offering a level of certainty that software-based firewalls cannot match.
🎯 Use Cases (4)
✅ Best For
- Replicating historian data to a corporate network without exposing the OT network
- Preventing any inbound network traffic to a nuclear power plant's control network
- Securing safety instrumented systems (SIS)
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Environments requiring bidirectional communication and control from external networks
- Low-security environments where a traditional firewall is sufficient
🏆 Alternatives
While firewalls can have vulnerabilities and misconfigurations, a unidirectional gateway offers a simple, physical guarantee that no external network traffic can enter the protected OT network.
