The benefits of modernization and digital transformation are driving businesses in every industrial segment to move to new cyber-physical system technologies, making it possible to gather and analyze rich asset data with greater efficiency and flexibility. But along with the productivity and safety gains that can be achieved, the need for comprehensive industrial cybersecurity protection also increases as the attack surface of the plant expands.

Leaning on our deep knowledge and global expertise in critical infrastructure protection, Nexus Controls designs and deploys holistic operational technology (OT) cybersecurity solutions tailored to the unique demands of your industrial plant network.


Nexus Controls can ensure that you have an effective cybersecurity program that meets the needs of legacy control systems, with limited expert resources, while accounting for modern technology and increasing cyber threats.

By leveraging Nexus Controls' 60-year industrial domain expertise and tailoring industrial cybersecurity solutions specific to customer industrial control systems (ICS) use cases, you can be confident that Nexus OTArmor™ exceeds alternative ICS cybersecurity solutions on the market today.
