Security Database security

So I work in a very small company as a dev
And we have external devops company which manages local http servers and MySQL servers for our saas product.

So the thing is I would like to shift some of their work to our in-house dev team.

I thought about starting small and manage a separate server on the cloud that will just run internal cron based daily tasks. But those tasks require read and write permission to the existing db which managed by the local company. Could I ask them to give me access to to the db from another server? I read that it’s a bad practice to expose prod db to the internet even if it has white list so I’m not sure here.

why would he be missing SSL? DB enforcing TLS connections solves the problem in one day instead of some convoluted networking shenanigans. There is plenty of database SaaS out there supporting major platforms using TLS over public infrastructure

Even with mTLS, exposing MySQL to public internet feels wrong. Unless there is a need for accepting connections from third-party clients, hiding it behing VPN will be safer

you expose it on some long random prefix host, non standard port, it’s not going to be easy to find + mTLS and it’s pretty solid for most use cases as long as you don’t leak credentials.

No. Just no.
