Cybersecurity for building automation – Building automation systems range from safety-critical to reliability critical: elevator controls must be protected from cyber sabotage, heating, ventilation and air conditioning (HVAC) systems must run and we cannot afford misoperation of HVAC systems that leads to equipment damage and long-term outages.

With Waterfall you get


Safe IT/OT Integration

Unidirectional Gateways enable management, contractor, vendor and even customer visibility into the operation of critical building automation systems, without putting those systems at risk of compromise by exposing them through a firewall.


Real-time security monitoring

Real time visibility into networks and building automation security configurations through Unidirectional Gateways increases protection for critical systems, without creating connections, and the cyber risks that come with connections, into protected systems to gather security data.

Safe Equipment

Safe Equipment Monitoring

Enterprise-wide and visibility into equipment availability, new equipment issues and developing problems through Unidirectional Gateways enable safe and efficient prioritization and scheduling of maintenance activities.

Use cases


The Waterfall for IDS product replicates mirror and SPAN ports from building automation systems out to IT-based OT IDS sensors, for safe OT network monitoring.

Equipment Monitoring

Unidirectional Gateways offer unbreachable protection to critical equipment, while replicating OPC servers, real-time databases, Syslog alerts, SNMP alerts and other critical performance indicators to enterprise systems and users, and external vendors and service providers.

Passenger Monitoring

Video feeds, turstile counters and other data is routinely replicated unidirectionally to IT networks to provide insights into passenger traffic patterns and bottlenecks, passenger safety issues and real-time rail / bus and shuttle scheduling.
