Guardtime

If Google organizes the world's information and makes it universally available then  Guardtime  validates that information and makes it universally reliable.  We are a  team of over 150 cryptographers,  developers and security architects, with decades of experience defending networks from nation-state attack. Strangely, no one has put the two (cloud and blockchains) together. If they did they would realize that together they would the solve the thorniest problem for Enterprise CIO.
 Guardtime offers its Defense and Aerospace partners next-generation anti-tamper hardware, solutions for defending critical networks from nation-state level attackers, designing and tailoring network defense or providing end to end data-centric security for sensor platforms.
