Cyber-security company IoT Defense has recognized a lack of protection for consumer devices and has formulated a hardware based solution, RATtrap.
RATtrap is a compact and efficient smart firewall for the modern smart home. It is intended to be an “out of sight, out of mind” type of online protection. Once plugged into your network, RATtrap protects all your internet connected devices from malicious hackers looking to gain access to your devices, data, and generally just breach your privacy.
