The operating system and code that your OnHub and Google Wifi run are guaranteed to have been signed by Google. Both devices participate in the Google Vulnerability Rewards Program (VRP) and eligible bugs can be rewarded up to $20,000 (U.S) We’re always looking to raise the bar to help our users be secure online. We spent significant time in building a security model into our implementation of 802.11s that Google WiFi and OnHub could use so that your network is always comprised of exactly the devices you expect. The result is a system where multiple Wifi Points work together to create blanket coverage.”]
