Personal hotspot hardware provider Karma has announced a new security-focused product, Karma Black. A specialized version of the company's KarmaGO hotspot device, Karma Black will provide anonymous browsing (Tor), an integrated Virtual Private Network (VPN), blacklisting and ad-blocking.

KarmaGO allows users to establish a WiFi connection through 4G via a small portable device, either on a pay-as-you-go basis or through a monthly data plan -- it's particularly popular with business travellers. Karma Black will operate in the same way, but will act as an invisibility cloak for users, encrypting web activity and hiding physical location. It'll also provide beefier protection against intrusive advertising and viruses.
