With Visma Addo, you get a safe solution that follows industry standards. All external communication is encrypted using up to 2048 bit.
This diagram shows the different components of Visma Addo and how they communicate. The main components are hosted inside Itadel, where they run in a closed environment.
Communication from Itadel
All communication from Itadel to external parties is encrypted using X.509 certificates. X.509 certificates X.509 is a standard for Public Key Infrastructure (PKI). A certificate issued by an authorized organization called Certificate Authority (CA) which is responsible for confirmation of identity. The certificate contains two keys for asymmetric encryption, a public key and a private key. The certificate owner is the only one who has access to the private key used for encryption. The encrypted content can be decrypted only with the matching public key. By relying on the certificate issuer, the sender’s identity is ensured and thus the content. Visma Addo supports encryption using TLS v1.2.
Communication with Nets and e-Boks
The communication with Nets and e-Boks uses a VOCES certificate issued by Nets. A VOCES is a merchant certificate that represent a business, it is used to secure communication between different parties. Visma Addo supports encryption using TLS v1.2.
Delivery of e-mails to a recipient requires encryption of attachments as they may contain sensitive personal information. The attached documents are encrypted up to 2048-bit AES (Advanced Encryption Standard).
