I'm sure one of my colleagues already discussed this with you, however I want to put it here for everyone else's reference. We currently do not have a static address for all applications to whitelist. We do have it for some applications like Salesforce and Quickbase. For applications like MySQL, the current workaround is to use our on-premise agent. Anyone who would like to try this out should contact us via our website live chat or by creating a ticket.
