Waterfall Security
Waterfall Security is a cybersecurity company specializing in industrial control system (ICS) and operational technology (OT) security solutions, particularly known for its unidirectional security gateways. These gateways allow data to flow from secure networks (like OT/ICS) to less secure ones (like IT/cloud) in one direction only, preventing cyberattacks from propagating into critical infrastructure. It provides hardware and software products designed to protect industrial environments, such as power plants, manufacturing facilities, and utilities, from external threats while enabling necessary data transfer for monitoring and analysis.
Developers should learn about Waterfall Security when working in industries with critical infrastructure, such as energy, manufacturing, or transportation, where securing operational technology networks is paramount. It is used to implement air-gapped or semi-air-gapped security architectures, ensuring that sensitive OT data can be shared with IT systems for analytics without risking reverse attacks. This is crucial for compliance with regulations like NERC CIP and for protecting against ransomware or state-sponsored cyber threats targeting industrial systems.
