Shadow Devices in OT Networks: The Assets Nobody Knows They Have

Maintenance laptops left connected, 4G modems installed by vendors, uncatalogued switches: shadow devices in OT networks are more common than you think and represent concrete blind spots for security.

Supply Chain Attacks in OT: The Vector That Bypasses the Physical Perimeter

Supply chain attacks are among the hardest to detect and prevent. In industrial OT, the supplier chain is often long, poorly monitored, and holds privileged access to control systems.

TAP vs SPAN Port in OT Environments: How to Choose Where to Place Sensors

Passive OT traffic monitoring depends on where and how traffic is captured. Hardware TAPs and SPAN ports have very different characteristics in industrial environments: a wrong choice means incomplete data or operational risks.

Triton/TRISIS: When Attackers Target Industrial Safety Systems

Triton/TRISIS is the first documented malware designed to disable Safety Instrumented Systems — the systems that prevent physical industrial accidents. Its impact goes beyond the targeted plant: it changes the perimeter of what must be monitored.

Cybersecurity in Water Networks: The Water/Wastewater Sector as a Forgotten Critical Infrastructure

Water and wastewater treatment plants are critical infrastructures with often obsolete OT systems and exposed remote connections. A sector that industrial cybersecurity still struggles to reach.

Zero Trust in OT: Applicable Principles and Real Limits in Industrial Environments

Zero Trust is the security framework of the moment, but applying it to OT environments requires pragmatism: here is what actually works and where the model shows its limits.

AI changed vulnerability discovery: but there is an OT gap you cannot ignore

New AI models discover vulnerabilities autonomously and at industrial scale. But the tools stay tuned for IT: the OT world risks falling behind just as attackers accelerate.
