KEEP YOUR DATA SECURE WITH THE TLS-450PLUS ATG

Frequent Software Updates
Stay ahead of potential threats and weaknesses with routinely updated operating software. Veeder-Root is also setting the industry standard when it comes to software deployment, including new tools like Centralized Device Manager that manages console software updates across a network.

System Security
Designed to limit system vulnerabilities, the TLS-450PLUS Automatic Tank Gauge segments security for optimal protection. This includes the use of partitioned Ethernet Ports to separate trusted network from internet, and the ability to reassign or control the availability of ports.

Custom User Access
Implementing a program for securing user access helps to reduce risks directly on the gauge. Using front panel security, username and password requirements, and predefined or custom user roles to assign permissions, the customer user access features of the TLS-450PLUS Automatic Tank Gauge support better data control.

Security is built into the process
Our iterative process to developing and releasing software updates for the TLS-450PLUS Automatic Tank Gauge includes multiple active security scans based on known industry vulnerabilities.
