NEW — SENTINEL SCANNER, FOR ROBOTS AND SMART DEVICES

Some robots ship with trapdoors: hidden tunnels that stream data back to the maker, and wireless controls anyone nearby can seize with no password. In 2026 the Pentagon listed one major maker as a Chinese military company and the FCC banned its new robot models, citing exactly those flaws. Sentinel Scanner audits any robot or device for that whole class of gaps before it is trusted on your network, then blocks the harmful paths and quarantines machines that fail. And for the newest threat — self-spreading AI worms hopping between unsecured home devices, which Anthropic warns could arrive within a year — WormShield watches for the moment a device starts spreading and cuts it off with the kill switch. A worm with no off switch meets a network that has one.
