All transaction information passed between merchant sites and the Protx VSP Systems is encrypted using 128-bit SSL certificates.

No cardholder information is ever passed unencrypted and any messages sent to your servers from Protx are signed using MD5 hashing to prevent tampering. You can be completely secure in the knowledge that nothing you pass to the Protx servers can be examined, used or modified by any third parties attempting to gain access to sensitive information.

Encryption and Data Storage

Once on our systems, all sensitive data is secured using the same internationally recognised 256-bit encryption standards used by, among others, the US Government.

The encryption keys are held on state-of-the-art, tamper proof systems in the same family as those used to secure VeriSign's Global Root certificate, making them all but impossible to extract. The data we hold is extremely secure and ProtX are regularly audited by the banks and banking authorities to ensure it remains so.
