MVP with Laravel - Security/encryption

Hi everyone,

I'm working on a product the will have a high bar for security as it will contain highly sensitive personal data.

Naturally, I need to make sure that user data is incredibly secure. I have a few thought on how to do that, encryption at rest is causing me some issues.

I use Laravel and Vue, with Forge to manage a digital ocean droplet. Does anyone have any advice on how best to implement encryption at rest? EU based.
