We use Protx (www.protx.co.uk) for our debit and credit card transactions. Protx provide secure online payment solutions for thousands of online and mail order businesses across the UK and are a division of Sage UK Limited.
Protx 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.
Protx 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.
Protx 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.
Protx is audited by an independent company Trustwave to ensure that we are up-to-date with the latest encryption and security standards and that we comply with the stringent standards set out by the card schemes. Trustwave is an independent Qualified Security Assessor (QSA) and an Approved Scanning Vendor (ASV) for the payment card brands.
