It should be Simple
A MuMu router will simply do what others claim, but in a novel way. As it protects your connection it protects what comes into your computer. Millions are spent to recognise any virus or vulnerability that roams the internet, but in the end do we really care about that? We decided that the only thing relevant in the end is to not get sick rather than knowing what you have been infected with.
While taking a close look at how anti-virus companies function in removing viruses from computers, we at MuMu systems didn't think that allowing any hack or infection that way made any sense. Why would you allow to be infected or hacked and then try to fix the problem? We thought it made more sense to put on the bulletproof vest before we get shot. Or as another example: when a gun is detected at the airport, you would want to take it away immediately instead of trying to find out what type of gun it was. Therefore, the MuMu router was developed.
