RouterCheck is the first consumer tool for protecting your home router, which is the gateway to your home network. Your home router is the computer in your home with the least protection, but the greatest vulnerability. If it is attacked, all the devices connected to your router are at risk. RouterCheck is like an anti-virus system for your router. It protects your router from hackers around the world, who have begun to target and attack routers.
