Opéra: Interoperability option

Convinced that client freedom ensures loyalty and that networks must be connected with those of competitors, Attestation Légale supports the implementation of an interoperability standard.

This standard, called Opéra, was co-founded by Attestation Légale. Opera ensures a secure standard which maximises coverage of operators' networks for its members.

Just one upload and your file will be available to all your clients on every platform which is part of this standard.
