Top OT Security Vendors You Should Know in 2024

Structured according to the five current NIST CSF functions

While operational technology (OT) has traditionally been separate from information technology (IT), that line is increasingly becoming blurred, resulting in new security challenges for organizations. Thankfully, there are now several OT security vendors who can help you secure your infrastructure. This article walks through the reasons for the OT/IT convergence, the different phases that OT departments go through in securing their connected infrastructure, and a list of OT security vendors that can help your infrastructure stay secure.   

The OT/IT Convergence  

For many, the distinction between OT and IT has historically been stark. Massive machines that were part of industrial control systems (ICS) were purely mechanical, standalone pieces of technology. These contained systems were not networked to anything, and troubleshooting had to be done onsite, often in remote parts of the world. It’s no wonder that OT was completely separated from IT—the technologies were fundamentally different, requiring a different set of skills to operate and troubleshoot.   

The merging of OT and IT began with the ability to network OT devices over the web. The flow of data from these once remote devices delivered a tremendous amount of value to critical infrastructure businesses. They quickly began bringing these once standalone devices online, whether in brownfield projects that networked previously unconnected OT devices or greenfield projects that had OT devices with connectivity directly out of the box.   

Today, the gap between OT and IT is not simply converging; it has altogether collapsed. The connectivity of OT devices presents the opportunity for a bad actor to exploit weaknesses of the device from the outside. With this change comes many new cybersecurity challenges for OT departments and a host of new OT security vendors that can help resolve them. But first, OT departments must be made aware that there is a potential threat that must be resolved.  

Phases of Securing OT  

With connected OT devices being relatively new, many OT departments go through a phased approach in their journey towards securing their infrastructure. It usually follows this pattern:   

Step 1: OT Security Kickoff   

This first stage is often initiated by the board, executive team, or department leadership as a response to recent cybersecurity failures (such as the SolarWinds hack) or to comply with government or vendor regulations. Whatever the case, the powers that be have declared OT cybersecurity to be a priority, leaving OT personnel scrambling to find the right processes to follow and/or the right OT security vendors to help them do so.   

Step 2: Asset Discovery and Cybersecurity Assessment  

In order to secure OT devices, you must first discover exactly what’s connected to your network. In this phase, the organization looks to document the network topology and all the connected assets that that attached to it. This is often the “eureka moment” when both management and staff realize how many devices are at risk for possible exposure, especially if they have not been updated or patched in a while. Asset discovery often leads to—or is done in tandem with—an OT assessment that looks at the risk exposure of the organization’s people, processes, and devices.   

Step 3: Risk Remediation, Process Optimization, and Threat Detection  

Now that the networked devices have been identified and the risk of exposure understood, it’s time to remediate the problems, optimize processes to prevent risks from cropping up again and ensure that there is proper threat detection. Remember: with connected devices it is not a matter of if your systems will ever be breached; it’s a matter of having the appropriate detection and response when they are compromised.  

Top OT Security Vendors You Should Know in 2024  

We have compiled a list of the top 15 OT security vendors we hear about most often on customer calls, and we have grouped them by the current five NIST CSF functions: identify, protect, detect, respond, and recover.

We’re not necessarily endorsing or recommending any of vendors here, but we do hear about them often and they are vendors that can assist organizations with their cybersecurity journey. That said, an organization must realize that there is indeed no “silver bullet” when it comes to securing OT devices. In fact, a successful strategy typically involves a number of these solutions working together in concert with policies that cover people and processes.

There Is No Single Solution  

With OT cybersecurity, there is no single product that is a cure-all for securing your infrastructure. In fact, that is one of the biggest errors many organizations make when initially putting together their  OT cybersecurity budgets: they look for one single solution to solve everything that ails them.   

Instead, it is important to realize you need a cybersecurity ecosystem built with many different OT security vendor solutions. You must be able to discover all the assets on your network, quickly assess their relative risk and exposure, provide visibility into the remediation of known issues, optimize future processes to minimize human error, and have highly intelligent threat detection and mitigation services in place.   

If you’re looking to take your OT cyber security program to the next level and need help assessing your critical infrastructure’s current state, SecurityGate is here to help.
