Ensure uninterrupted operations with OT Security
Holm Security provides a complete platform to protect your physical operations from manipulation, sabootage, and disruption - without interrupting your business.
The challenge of securing OT
Poor visibility
Lack of visibility in an environment can adversely affect security and production. Identifying vulnerabilities before cybercriminals infiltrate systems is vital in OT networks, as it helps prevent unplanned downtime and mitigate operational disruptions.
IT/OT integration
The integration of IT and OT increases risk, as threats from the IT side can easily infiltrate unpatched OT systems. With an increased attack surface, cyber security teams are compelled to prioritize the security of OT environments.
Legacy Infrastructure
Organizations managing OT infrastructure often heavily rely on legacy, unsupported operating systems. While gradually updating old infrastructure helps, limiting access to the most “remote” parts is key, as well as disabling non-standard ports and regularly scanning networks for potential threats.
Cloud attack surface
Combining cloud services with integrated IT/OT creates a more vulnerable attack surface. Cybercriminals are exploiting insecure OT devices to gain unauthorized access to cloud infrastructure.
Holm Security meets the threat head-on
At Holm Security, we extend our vulnerability management capabilities beyond traditional IT systems to include Operational Technology, providing complete visibility across both digital and industrial networks.
Fast and precise asset discovery
Our active scanner goes beyond passive monitoring. It actively engages with OT devices to uncover what others miss. It identifies hidden or silent assets, collects software and firmware details, and highlights vulnerabilities and misconfigurations. You’ll gain clear visibility into open ports, installed applications, security settings, and even indicators of known threats - helping you build a stronger, more resilient OT environment.
Unauthenticated & authenticated scanning
Unauthenticated scans use an outside-in approach, assessing endpoints, servers, and infrastructure without requiring a login. Authenticated scans go deeper, using credentials to access devices and examine them from the inside out. When combined, these methods provide a comprehensive view of your OT environment, helping you identify hidden risks.
Agent-based asset discovery
In OT environments, many devices are hard to detect through network scanning alone. Our lightweight endpoint agent ensures accurate asset discovery, continuous monitoring, and faster identification of vulnerabilities - without disrupting critical operations.
Covering 75+ vendors
A tailored SCADA scan configuration
We’ve developed a dedicated SCADA scan configuration designed to minimize operational impact while still uncovering critical weaknesses. Our scanner supports systems from over 75 different OT and SCADA vendors, with coverage consisting of more than 1,600 vulnerability tests and over 3,700 unique vulnerabilities across industrial infrastructures. This extensive coverage includes key components, such as SCADA servers, engineering stations, and control-level devices, including PLCs and HMIs.
Industrial protocol awareness
Our platform also understands the industrial protocols that power these environments, including Modbus/TCP, Profinet, EtherNet/IP addresses, Siemens S7, OPC, IEC 60870-5-104, and DNP3. This deep protocol awareness allows us to safely assess systems that traditional IT-focused scanners cannot, offering a comprehensive and reliable view of vulnerabilities across the entire OT ecosystem.

Frequently asked questions
What is Operational Technology (OT)?
Operational Technology (OT) refers to the digital systems, including hardware and software, used to monitor, control, and automate physical processes in the real world.
What is OT security?
OT security protects your digital systems by identifying vulnerabilities before they are exploited by cybercriminals. This allows factories, utilities, and critical infrastructure to run safely and reliably.
Why is OT security important?
Many OT systems were not originally designed to be connected to the internet, making them vulnerable and susceptible to manipulation or sabotage.
How do I get started with Holm Security’s OT Security?
All organizations can implement Holm Security’s platform, taking just a few hours to get started. OT Security is a feature within our product System & Network Security.
