PRODUCT FEATURE

OT security: vulnerability management for industrial systems

Holm Security extends the same vulnerability and exposure management you already run across IT, network, web, cloud, and identity into OT and SCADA, giving you one view across both your digital and industrial networks, assessed on your terms.

CAPABILITIES

Vulnerability management built for OT and SCADA

We detect vulnerabilities in systems from more than 75 OT and SCADA vendors, including Siemens, ABB, Schneider Electric, Rockwell Automation, and Honeywell.

Broad vendor coverage

 1,800+ vulnerability tests and 4,200+ unique vulnerabilities across SCADA systems, industrial control devices, and the Windows workstations that manage them.

Low-impact by default

Read-only checks that stay within your configuration, so you can assess fragile equipment with control over scope, timing, and intensity.

Industrial protocol awareness

Modbus/TCP, Profinet, EtherNet/IP, Siemens S7, OPC, IEC 60870-5-104, and DNP3, reaching systems that IT-focused scanners cannot.

Authenticated and unauthenticated assessment

An outside-in view of exposed services plus a credentialed inside-out view, for a complete picture of risk.

Windows OT coverage without probing

A lightweight Device Agent inventories engineering stations locally, the safest option for sensitive Windows hosts.

Most organizations have more OT than they realize

From badge readers to building management systems, the OT you cannot see is the OT you are not assessing, and attackers know it.

Frequently asked questions

What is OT security?

OT security is the practice of finding and reducing vulnerabilities in operational technology, the hardware and software that monitors and controls physical processes like production lines, energy, and water systems. It protects these systems from manipulation, sabotage, and disruption. Unlike IT security, it has to account for equipment that is often old, sensitive, and cannot tolerate aggressive scanning.

What is the difference between IT and OT security?

IT security protects data and information systems, while OT security protects the physical processes and industrial equipment that run operations. The main difference is tolerance for disruption: an IT system can usually be patched or rebooted, but an OT device controlling a live process often cannot, so OT security has to prioritize availability and use low-impact assessment methods.


Why is OT security important?

OT security matters because many industrial systems were never designed to be connected to the internet, which leaves them exposed to manipulation and sabotage. When an OT system is disrupted, the impact goes beyond data loss and can affect safety, production, and essential services. As IT and OT networks converge, threats that start on the IT side can increasingly reach unpatched OT systems.


How do I get started with OT security at Holm Security?

OT security is part of System & Network Security within the Holm Security Platform, so you can get started within a few hours. Share your OT and SCADA product list and we will confirm your coverage from there.

Does OT security help with NIS2 compliance?

Yes, OT security supports NIS2 compliance by giving you continuous visibility into vulnerabilities across industrial systems, which underpins the directive's risk management and cyber hygiene requirements. Regulated and critical sectors such as energy, water, and manufacturing fall directly in scope.
