DOME Sentry by Veridify Security is a cybersecurity appliance designed to protect currently installed devices and legacy systems. It acts as a security gateway in front of installed devices or controllers, delivering authentication and data protection functions similar to new DOME-enabled devices. DOME Sentry provides real-time protection without requiring changes to existing building management systems or devices. It secures thousands of connected devices, including HVAC systems, lighting systems, elevators, and access controls in commercial, government, and educational facilities. DOME Sentry is part of a NIST-compliant Zero Trust framework, ensuring every device is authenticated and managed to create a safe operational environment. It is platform agnostic and can run over existing BACnet installations, making it easy and cost-effective to authenticate every device, user, and command while encrypting and protecting building data. DOME Sentry's zero-touch provisioning saves time and money by automating the installation of secured devices and associated digital certificates and encryption key provisioning.
