An industrial firewall deployed in a corporate data center and one deployed at the edge of an oil and gas processing facility are solving nominally similar problems with fundamentally different constraints. The data center device operates in a climate-controlled environment with stable power, minimal vibration, and a maintenance team minute away. The industrial edge device […]
For most of the past decade, OT security occupied the margins of the enterprise security conversation. The assumption that industrial networks were isolated, that operational technology was too specialized to attract serious adversary attention, and that the cost of security investment outweighed the risk of inaction, these assumptions shaped budget decisions and security program priorities […]
The assumption that a factory is safe because its network is physically isolated from the internet has not been valid for years. Remote maintenance connections, supplier integrations, wireless sensor networks, and IT/OT convergence projects have collectively dismantled the perimeter that industrial security once depended on. Ransomware incidents affecting automotive plants, water utilities, and food manufacturers […]
Selecting the right OT security vendor is one of the highest-stakes procurement decisions a plant CISO or OT program manager makes. This guide profiles 10 leading OT security vendors, covering product focus, strengths, deployment models, buyer caveats, and suggested RFP questions, giving procurement teams a practical shortlist framework and the right questions to ask before […]
2026 is not a routine year for OT security. The convergence of IT and OT networks is accelerating, regulatory frameworks including NIS2 in Europe and updated NERC CIP standards are driving compliance obligations into operational environments, and ransomware groups have demonstrated both the capability and the willingness to target industrial infrastructure directly. If your program […]
Modbus is everywhere, and it was never designed to be defended. First published in 1979, it remains the most widely deployed industrial protocol in SCADA and PLC environments globally, running on everything from water treatment controllers to power grid RTUs. It carries no authentication, no encryption, and no session integrity. In threat terms, that means […]
Cybersecurity incidents have evolved from isolated IT problems into enterprise-wide crises that impact operations, finances, reputation, and even safety. For organizations operating in critical infrastructure, manufacturing, energy, and industrial environments, a data breach can be far more damaging than the immediate technical incident suggests. While the headlines often focus on the initial breach cost-legal penalties, […]
The IT/OT gap is not a technology problem, it is an organizational one with a technology surface. In 2026, despite cloud-connected historians, unified security platforms, and converging network stacks, the divide between information technology and operational technology teams remains one of the most consequential structural vulnerabilities in industrial cybersecurity. The priorities are genuinely different: IT […]
Operational technology environments do not forgive slow responses or unsafe remediation choices. A misconfigured containment step in a power substation, a premature return to automated control after a PLC compromise, or an uncoordinated vendor escalation during active ransomware deployment can each produce consequences far more serious than the original incident. OT incident response is a […]
The operational technology (OT) attack surface is expanding rapidly. As hybrid IT/OT estates converge and regulatory mandates like NIS2 and NERC CIP tighten, industrial environments can no longer rely on air gaps alone. Defending critical infrastructure requires toolchains that operators can deploy without risking physical process disruption. For plant security managers and architects, finding the […]
