My IT processes are being audited by an external auditor and I have to provide detail of encryption used on third party sites. Can anyone advise the encryption used on Sage Payroll encryption?

For example Microsoft says about O365:

We have multiple layers of encryption in place at the same time, our data is encrypted at rest and in transit, using several strong encryption protocols, and technologies that include Transport Layer Security/Secure Sockets Layer (TLS/SSL), Internet Protocol Security (IPSec), and Advanced Encryption Standard (AES).
