Effective asset management improves OT security by quantifying risks and identifying unauthorized communications
Nozomi Networks currently offers add-ons, such as ARP agents, that can be installed on machines to expand the information we receive from sensors. However, these are part of a licensing structure, which can be costly. It would be very helpful if these agents were available free of charge. The solution itself has no major problems, but this is a feature request I would make for improvement.
