Revolutionising Connectivity for Critical Infrastructure: Private internet off the cloud (IOTC) Secure, Reliable, and Always On.
Critical infrastructure demands secure, reliable, and purpose-built networking solutions to ensure seamless operations across local and wide-area environments. IT4A’s Connect services deliver next-generation networking that combines high availability, Zero Trust principles, and industrial-grade reliability to meet the specific needs of operational technology (OT) systems.
Our solutions are designed to ensure that your systems, operators, and maintainers stay securely connected, whether they’re on-site, across a wide area, or accessing remotely. IT4A eliminates the vulnerabilities and limitations of traditional networking, providing certainty in connectivity for critical operations.
1. Zero Trust Remote Access Service (ZTRAS)
2. Zero Trust Local Access Service (ZTLAS)
Specialist contractors, integrators and maintainers need remote access to keep operational systems running. Shared accounts, permanent connections and undocumented access routes are among the biggest risks to OT network security. ZTRAS replaces them with zero trust network access, so each user reaches only the systems they are approved to use, only when they need to.

Connect is one of the four IT4A foundations, alongside Supply, Host and Protect. From SCADA network design and site-wide LANs to private wide area networking and ZTRAS, it turns OT network security into three outcomes: Visibility, Control and Assurance.
In managed office buildings, Connect provides the secure landlord network and contractor access behind OT Assurance for Managed Buildings.
A clear picture of your OT network topology, access routes, segmentation and connectivity dependencies, documented so nothing is hidden.
Secure remote access through ZTRAS, network segmentation, firewalling and contractor access governance decide who can reach each system.
Resilient connectivity, access logs and remote access evidence show your OT network is secure and keeps operations running.
IT4Automation visited to perform a network survey and assisted with troubleshooting a network issue… I was very pleased with the service that IT4Automation provided and would certainly contact them again in the future if needed.

Great communication, reliable and your team… worked pretty much non stop start to finish. I think this upgrade has made a good improvement to the machine and will improve reliability.
