Portrait

Since 2006, certSIGN has been the leading Romanian provider of trust services and a pioneer on the Romanian market in the introduction of paperless technologies in business processes.

With tokenized electronic signatures, you can quickly and legally sign any document under your sole control using a secure cryptographic signature creation device (token) and a unique PIN code. And because every change to an electronically signed document is verifiable, fraud attempts can be almost completely eliminated, unlike a handwritten signature on paper.
