A founder's guide to application security
Security basics every founder should understand before shipping — explained in plain language, with practical steps.
You don't need to be a security engineer to ship responsibly — but you do need to understand a few fundamentals. Here's a plain-language guide for founders.
Protect data with access rules
The single most important habit: make sure users can only see their own data. In Getyn, enabling a backend enforces row-level security, so every table needs an access rule before it goes live.
Keep secrets on the server
API keys and tokens should never live in browser code. Getyn stores connector credentials server-side and injects them at runtime, so they don't end up in your published bundle.
- Give each user access only to their own records.
- Never ship secret keys to the browser.
- Use authentication for anything sensitive.
Validate input and handle errors
Assume input can be wrong or hostile. Validate forms, handle failures gracefully, and don't leak internal details in error messages.
For how Getyn approaches this at the platform level, see the Security page.
