How or what to encrypt the database?

Question

Encryption

Good afternoon.
There is a Bitrix24 database. Many things that are stored there are unencrypted. For example chat messages. The whole thing should be encrypted.
Since picking in the Bitrix itself did not lead to anything, I'm interested in the ability to encrypt the database, but so that Bitrix would not suspect about it.
For example, is there any "proxy" for mysql, so that Bitrix would contact the "proxy" for data, which, in turn, encrypts them (or decrypts them depending on the request), and returns the data in unencrypted form. And he wrote to the database in encrypted.
Or maybe there are some other options?
