Ensure reliable and efficient building operations

Many BMS operations also contain IT and IoT-based assets such as access control systems and security cameras. If you only have visibility into your OT assets, you may be blind to up to 50% of your BMS environment. Tenable One OT Exposure desilos your operations so you get the visibility you need to see and secure more.

Because BMS relies on a heterogeneous user community to interact with and maintain a variety of systems, security incidents can be hard to spot. Tenable One OT Exposure's unique hybrid threat detection methodology employs policy, anomaly and signature-based detection technologies to find more attacks, whether they are known, zero-day or targeted attacks. This helps to alert on questionable behaviors before they impact your operations.

BMS has many discrete systems, each using different protocols. Tenable One OT Exposure goes deeper than network-only detection and gives you deep situational analysis into firmware versions, user access, ladder logic and much more. This enables you to spot potential security incidents and appropriately schedule cyber maintenance for your BMS system assets.

BMS system elements and related vulnerabilities are increasing, so you need to know which ones to address first. Tenable One OT Exposure uses a Vulnerability Priority Rating (VPR) to identify relevant vulnerabilities for your exact system—across IT and OT assets—and triages them with a score. You’ll know which vulnerabilities are the most severe so you can deal with them first.

Tenable One OT Exposure enables you to centrally track your diverse building management systems for unscheduled and unauthorized changes. Its configuration control capabilities alert you immediately when a malicious actor or an employee or partner makes a mistake and alters a controller.
