NexDefense

NexDefense, founded in 2012, is another security startup focusing on securing the vulnerabilities in industrial equipment. This company's products help operators discover communication channels in their operational technology systems without disrupting operations, build and manage a baseline of known devices, visualize control system network activity, and – most importantly – locate and evaluate abnormal events on their networks.

Most recently, the company hired former Cisco executive Matt Morris as vice president of product and strategy.
