Zertificon offers AS4 certificate triples in combination with our solution Z1 Energy Market Communication. The certificate triples are from the registered Sub-CA DARZ.CA. We offer competitive pricing and a smooth process for purchasing and renewing certificates that comply with all requirements. Additionally, we can assist with test-CA-certificates.

EMail Zertifikate

Email certificates according to EDI@Energy standards using RSASSA-PSS algorithm via SwissSign

Furthermore, you can obtain S/MIME email certificates in compliance with the EDI@Energy guidelines for exchanging schedule data and Redispatch 2.0 messages directly through Zertificon. Our partner for email certificates is the certification authority SwissSign.

As email will serve as a fallback option for schedules transmission, energy companies with roles such as Balancing Responsible Parties (BRP) and Transmission System Operators (TSO) are likely to continue using S/MIME email certificates that meet EDI@Energy standards.

Certificates from Zertificon can only be ordered in combination with the Z1 software solution

You can order S/MIME and AS4 certificates from Zertificon only when using our Z1 products. In order to begin receiving certificates via our interfaces, you must have access to certain features within our Z1 software. However, if you’re only looking to purchase certificates, we recommend contacting the CA of your preference.

Please note that Zertificon does not offer AS4 or email certificates as standalone products.
