AS4 certificates in accordance with the Smart Metering PKI standards of BSI from the sub CA Atos

You can acquire AS4 certificates directly from Zertificon only in combination with our solution Z1 Energy MarketCommunication. We offer certificates through the registered sub CA Atos. Take advantage of our competitive pricing and streamlined process for procuring and renewing certificates. Our solution ensures that you remain compliant with BSI Smart metering PKI requirements, including those related to Test CA certificates, all without any hassle.

Don’t delay and reach out to us; the procurement of new AS4 certificates may take several weeks.

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.

To learn more about this topic, please read our blog post: AS4 switch in Market Communication: BRPs face unique challenges in future schedule management.

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.
