HVAC vendor as entry vector
Target 2013 — HVAC vendor credentials compromised, leading to POS network breach. The OT layer was never the goal, but it was the door.
Solutions · Building Management
From HVAC to life safety — validate every controller continuously.
OT integrity for hospitals, data centers, campuses, and commercial real estate — where HVAC, access control, fire/life safety, and elevator systems are monitored at Level 0 and Level 1 with the same rigor as critical industrial infrastructure.
Aligned to
- NIST SP 800-82 rev3
- IEC 62443
- MITRE ATT&CK for ICS
- NERC CIP
- DoW Zero Trust for OT
Why it matters in Building Management
The risks building management can't afford to miss.
Unauthorized HVAC tampering
Direct control of building HVAC affects patient safety in hospitals, equipment cooling in data centers, and operational continuity across all building types.
BACnet device drift / spoofing
BACnet wasn't designed for security. Drift, replay, and unauthorized writes go undetected without integrity validation at the controller.
Fire / life-safety integrity
Suppression and detection systems must be validated continuously — alarms-only monitoring is insufficient evidence for life-safety risk.
How OTegrity helps
What OTegrity does for building management.
BACnet behavioral baseline
Per-device baselines for HVAC, lighting, and access controllers across BACnet/IP environments — drift and unauthorized writes flagged within seconds.
Life-safety integrity
Continuous behavioral validation of life-safety controllers alongside their integrity state. Anomalies during unauthorized changes are classified as Cyber Attack.
Hospital & data center reliability
Where uptime is patient safety or revenue, OTegrity treats every building controller with the same rigor as a chemical plant SIS or substation RTU.
