Future-proof and scalable solution for cyber security,
data protection and long-term archiving.
KSI® Blockchain timestamping unlocks the digital trust needed for ambitious digitization projects, such as going cloud-native, broadly adopting AI, or moving to automated machine-to-machine processes.
KSI® Blockchain was first developed in 2008 for the Government of Estonia to secure its critical health, justice and business data.
Since then, it has been deployed by the world’s most demanding customers, including the numerous governments and leading companies in telecoms, aerospace, defence, energy, financial services and insurance.
Guardtime’s KSI® Blockchain Timestamping Service is compliant with the eIDAS regulation and included in the European Trusted List.
KSI® is the first blockchain-based technology to receive an eIDAS accreditation and marks an important step in the evolution of digital trust technologies. Accreditation was conducted by TÜV Nord, Germany.
Main Advantages: Unique benefits compared to existing timestamping solutions
KSI Blockchain timestamping scales to millions of events per second to support the volumes needed for the most ambitious data-driven solutions in the public and private sectors.
KSI Blockchain timestamps can be verified independently of Guardtime or any third-party service provider by a widely witnessed blockchain-based trust anchor.
KSI timestamps can be stored and verified indefinitely, without the need for complex crypto-lifecycle management. KSI Timestamps are immune to quantum computing attacks, which makes them ideal for long term archiving and future-oriented projects.
KSI Blockchain has been in continuous operation for over a decade and is designed to exceed enterprise reliability requirements, backed by industry-leading SLAs.
