New: Z1 Energy MarketCommunication now supports AS4
In August 2023, we’re rolling out the beta version of Z1 Energy MarketCommunication for AS4.
Z1 solutions streamline the switch to AS4 through high degree of automation for our customers.
Automatically manage AS4 certificates
Zertificon is a leader in automated certificate management. Z1 products seamlessly handle every phase – from procurement to continuous certificate management, including the search for market partners’ certificates. In addition to email certificates compliant with the EDI@Energy’s RSASSA-PSS algorithm, Zertificon now also offers procurement and management of AS4 certificate triples.
Hassle-free AS4 Path Switch
Z1 Energy MarketCommunication can fully automate the AS4 Path Switch management for all or individual market partners, ensuring compliance without the stress.
Z1 Cryptographic Module – a cost-effective alternative to HSM
Is the use of an HSM mandatory according to the Smart Metering PKI guidelines? Not if you are a passive external market participant. Zertificon offers an affordable alternative to HSM for Security Level 1. It’s called Z1 Cryptographic Module.

What happens if my communication partner can’t follow all the EDI@Energy rules?
In this case our solution offers a feature called Clearing Case Management.
If, for example, your partner doesn’t use the latest encryption and signing algorithm, messages are sent to a designated clearing case inbox.
This allows you to process messages in a structured way. If clearing cases accumulate in short period of time, you’ll receive alert notifications. Also, for specific market partners addresses, you can set up custom email rules (policies) that are a bit more flexible with the compliance rules. This ensures a smooth flow of communication, even if there are minor deviations from the standard.
