Security

Protx as a Payment Service Provider, thousands of businesses outsource their transaction security to us. It is our top priority to ensure that transaction data is kept secure at all times.

Transaction security

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 we are regularly audited by the banks and banking authorities to ensure it remains so.

Links to banks

Protx has multiple private links into the banking network that are completely separate from the Internet and which do not cross any publicly accessible networks. Any cardholder information sent to the banks and any authorisation message coming back is secure and cannot be tampered with.

Employee access

No individuals within Protx or Gravelles are able to decrypt transaction information or cardholder data. Our systems only allow access to our most senior staff and only in extenuating circumstances (such as investigations of Card Fraud by the Police). Your transaction information and customer card information is secure even form our own employees because our systems never display the full card numbers, even on administration screens.
