Ziurra, certified communication

E-Administration, that is, digital transactions between citizens, governments, companies and clients, has become a significant challenge today, with government and businesses endeavouring to offer continuous service and more effective processes.


As both a Certification Authority and a Timestamping Authority, Izenpe can act as a trusted third party ("digital notary"), certifying legal act and contracts. For this reason, Izenpe has created a service giving proof that an email has been sent and received by the receiver.


Simple technology with legal validity


In other words, provide citizens and entities with an instrument for sending emails which verifies the time they are sent and ensures their integrity, in addition to proof that can be presented to a third party.
