Protecting an OT infrastructure relies on three steps: discover, isolate, monitor. This progressive approach, supported by solutions designed specifically for OT, allows organizations to increase cyber maturity without compromising operational availability. In OT, detecting is not enough\u2014you must structurally block threats before an attack spreads.<\/strong><\/p>\n

\n

Why IT solutions don\u2019t work in OT<\/strong><\/p>\n

\n

IT cybersecurity tools (antivirus, EDR, next-gen firewalls) are not suited to industrial constraints: frequent updates incompatible with maintenance cycles, false positives that can trigger production shutdowns, and an unmanageable volume of alerts for often limited teams. Against an OT ransomware attack or a targeted attack on a PLC, the delay between detection and response can be enough to cause production stoppages or industrial accidents.<\/p>\n<\/div>\n<\/div>\n

\n

Step 1 \u2014 Map assets and flows (visibility)<\/strong><\/p>\n

\n

You can only protect what you know. Seclab Xplore passively maps connected assets, network flows, and vulnerabilities without ever interacting with the equipment. This continuously updated inventory forms the foundation of any OT cybersecurity strategy.<\/p>\n<\/div>\n<\/div>\n

\n

Step 2 \u2014 Isolate what is critical (protection)<\/strong><\/p>\n

\n

Once critical assets are identified (the MVDI), network physical isolation via Xchange removes any direct connectivity between critical assets and risky zones. USB isolation via Xport closes the second major attack vector in OT environments. This step is decisive: it structurally blocks attack propagation even before detection occurs.<\/p>\n<\/div>\n<\/div>\n

\n

Step 3 \u2014 Continuously detect deviations (monitoring)<\/strong><\/p>\n

\n

In OT, network changes are less frequent than in IT. The most effective approach is to detect deviations\u2014new flows, new devices, behavior changes\u2014rather than identifying each threat individually. This method produces fewer false positives and is suited to OT teams. Pre-isolating critical assets reduces the monitoring surface and the volume of alerts to manage.<\/p>\n<\/div>\n<\/div>\n

The Seclab Xcore Platform integrates these three steps: Xplore (discovery and detection), Xchange (network isolation), Xport (USB protection).<\/p>\n

\n

Key takeaway<\/em><\/strong> \u2014 <\/em>Protecting an OT infrastructure: discover (Xplore), isolate the critical (Xchange + Xport), then monitor deviations (Xplore). In OT, isolation must precede detection\u2014detecting without blocking is simply chasing the attack.<\/p>\n<\/blockquote>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
