Separate IT and OT to Reduce Risk and Lower Costs

Although it is a common practice to run Operational Technologies (OT) on the IT network, there are drawbacks. Converging these systems, running IT and OT on the same network, is done to reduce costs and improve security. Converging these systems seems sensible, but it doesn’t really achieve either goal.

Building OT Savings

Security Risk

Your IT network and Building OT face different threats. When you combine them on the same network, you expose both systems to the weaknesses of each. Furthermore, should your network go down, not only do you lose IT functions, but surveillance, access control, and other critical building systems.

Port Costs

There is a cost associated with monitoring and maintaining every port. A typical cost per internal port would be $50 per month, and typically $100 per month for external ports. However, with Secure Utility, all per-port costs are eliminated and transferred to the OT solution providers. Since those providers are responsible for routine upkeep of their systems and edge devices, they should also support the networks they are on.

Firewall Costs

Operational Technologies must be secured by a firewall when using a traditional IT network. Secure Utility directs all traffic to Secure Utility’s Bank Grade Firewall, eliminating the need for redundant firewalls at every property to protect your OT systems.

Bandwidth Costs

Operational Technology demand on network bandwidth continues to grow as buildings become smarter and more connected. This incremental demand may strain existing IT infrastructure.

Connect Your Building OT with Secure Utility

Secure Utility is ideally suited to protect Operational Technologies. It offers a Secure Private Cellular Network on the back-haul channel that directs all traffic to our Bank-Grade Firewall. This solution provides instant notification of threats and at a lower cost than on-site firewall protection.

By separating IT and OT networks with Secure Utility, you can assign OT network maintenance to your solution provider. You also prevent threats and IT outages from impacting your critical building systems.
