Stay compliant with data protection regulations, as compliance is not only a legal requirement but also a way to demonstrate to your users that you take their data security seriously.

By following these steps and making security a cornerstone of your development process, you will create a secure environment for your Supabase backend that earns the trust of your users and stands up to the challenges of the digital world.
