OT Security Solutions for Visibility

There are different types of OT security solutions on the market that provides or promise to provide you with full visibility of your OT environments and do more. But not all solutions are equal and or have full end-to-end coverage.

Only handful of niche OT security visibility solution specific vendors left out there and many of such have been acquired by OEMs and or other big technology players.

Below are a list of OT visibility security solutions providers, acquisitions and market insights, in no particular order:

• Verve → acquired by → Rockwell Automation. Keeping the name so far.

• SCADAfense → acquired by → Honeywell.

• Indegy → acquired by → Tenable. Changed it to Tenable OT.

• CyberX → acquired by → Microsoft. Changed it to Azure Defender for IOT.

• Securitymatters SilentDefense → acquired by → Forescout. Changed it to

• Sentryo → acquired by → Cisco → Changed it to Cyber vision.

• Mission Secure → acquired by → Service Now.

Besides these players and acquisitions there’s a handful of other providers:

• Dragos, Nozomi, Claroty and Armis remains to name a few leading ones in this space (in no particular order), they have acquired some significant funding as well in the recent past.

• OTBase are another interesting product focused on asset management.

• Darktrace, Industrial defender, Opswat, TxOne and others have similar solutions.

• We also have few new niche players in the mix with some interesting offerings like Exalens, Phosphorous, EmberOT and more.

• Few other technology players like PA, Fortinet etc. do offer visibility through a portfolio of their solution stack but not a single product.

Some of the above solutions only provide passive capabilities for network level visibility and deep packet inspection, some also offer add-ons for active capabilities and endpoint visibility at an additional cost. Some are unique in a sense that they are endpoint / agent driven. Only few have capability released for wireless etc.

While most of these offer vulnerability identification, vulnerability management is an add-on and limited to only a few among the mix.

There are claims for all having AI features now (as buzz word), but there are use of some Machine Learning detection capabilities which would differ significantly.

Most of the top ones now seems to have come up with almost similar functionality or features in the last one year or so and compete against each other.

Some of these solutions have lost market share, changed product directions and or have a uncertain future ahead.

So choosing the right one would be essential for your specific OT security objective, use case and for your specific environment needs.
