Security Level Indicator

 

Security Level Indicator (SLI) is a numeric value embedded in payment card transactions that indicates the level of security applied to the transaction. It is part of the information exchanged during the authorization process between the cardholder’s issuing bank and the merchant’s acquiring bank.

SLI helps assess the security features associated with the transaction, such as whether it adheres to Strong Customer Authentication (SCA) requirements. Different SLI values correspond to varying levels of security measures implemented during the transaction, providing insights into the authentication methods used.

SLI is particularly relevant in regions or under regulatory frameworks that mandate specific security standards for electronic payments. Monitoring and analyzing SLI values contribute to the overall security and compliance posture of electronic transactions within the payment ecosystem.
