Payment Security
Below is an explanation of the security implemented on the Sage Pay servers.
System security
Sage Pay’s systems are scanned quarterly by Trustwave which are an independent Qualified Security Assessor (QSA) and an Approved Scanning Vendor (ASV) for the payment card brands.Sage pay is also audited annually under the Payment Card Industry Data Security Standards (PCI DSS) and is a fully approved Level 1 payment services provider, which is the highest level of compliance. We are also active members of the PCI Security Standards Council (SSC) that defines card industry global regulation.
Transaction security
All transaction information passed between merchant sites and Sage Pay’s systems is encrypted using 128-bit SSL certificates. No cardholder information is ever passed unencrypted and any messages sent to your servers from Sage Pay are signed using MD5 hashing to prevent tampering. You can be completely assured that nothing you pass to Sage Pay’s 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
Sage Pay 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.Internal Security
Entry to Sage Pay is controlled by Iris Scanners, which are the latest and most precise biometric security devices available for identification. As used by chemical plants, airports, police stations, prisons and other facilities where security is paramount. In addition, no one can enter or leave the building without a valid security pass.How it Works
- A customer selects the goods they wish to purchase from our website and enters their order and delivery details.
- The customer's credit card details are captured securely by Sage Pay.
- The customer will be prompted to enter their Verified by Visa or MasterCard Secure Code password on their card issuer's page (optional).
- The merchant bank sends the credit card details to your customer’s card issuer who authorises or declines the transaction.
- The merchant bank then sends the transaction results back to Sage Pay.
- Sage Pay sends the authorisation results back to us and the customer to confirm the results of the transaction.
