Your digital documents are irrefutable evidence with certified CERTIGNA timestamps

Market challenges

For a digital document, an electronic timestamp provides a reliable date affixed to a file that guarantees its integrity. Not only does it timestamp the file to the nearest second, but it ensures that its contents have not changed.

For example, a timestamp is used to date an electronic signature, verify the time a digital document was received, certify banking transactions, or affix an issue date to an invoice.

Certified timestamps increase the security of your digital and electronic signatures and codes by affixing an irrefutable date and time to the respective document.
