Armis

Founded in 2015 by Yevgeny Dibrov and Nadir Izrael, both alumni of Israel's Unit 8200 intelligence corps. The premise is that you cannot protect what you cannot see: the platform listens passively to traffic and builds an inventory of every thing moving on the network — office PCs, IP cameras, medical equipment, industrial controllers — and flags the ones behaving oddly or carrying known vulnerabilities. The angle targets exactly what classic antivirus misses: devices where no agent can be installed. Insight Partners acquired the company in 2020, but it continues to operate under its own name.
