A:Answer By their very nature NO router has security, unless you configure it.
However, virtually all new wireless routers, including this one support a variety of technologies for securing your network, which can easily be configured during the self-guided setup process included with this router. I personally recommend the latest and most secure, which is WPA-2.
This router also has an additional security option allowing you to configure a guest wireless network, which allows you to have one password for you and one for visitors. I STRONGLY recommend doing so, because it will allow you to grant access to friends and family, while not compromising the integrity of YOUR network or devices.
So while security is technically "not included" the ability to support it very much is. Just follow the on screen, step by step instructions when you configure your network and you will have a secure wireless environment.
