CTOs on the Move

Guardtime brings transparency and accountability to digital society. Founded in 2007, Guardtime invented Keyless Signature Infrastructure (KSI) - a technology that allows any type of electronic activity to be independently verified using only formal mathematical methods, without the need for trusted administrators. Deployed by world governments, KSI provides an independent audit trail for everything that happens in digital society, limiting liability and making it impossible for insiders or sophisticated cyber attackers to manipulate data and cover their tracks.
