"The Swedish company, Arenim Technologies, designed CryptTalk to foil hackers even if they have access to the system plans or the source code. CryptTalk features best practice security tech, and offers perfect forward secrecy and protection from man-in-the-middle attacks."
Asked for comment by POLITICO, Paul Rausch, founder of Greenwire, a U.S.-based IT consultancy, cautioned that "all systems have insecurities," but said that while "most commercial grade systems provide only a veneer of security" in order to meet the legal compliance needs, the CryptTalk team "appears to be actively taking many steps to try and address [these insecurities]." Indeed, few companies do not have back doors, CryptTalk thus only has two or three competitors in the very secure segment.
