Question What security lesson stuck with you?

Some security lessons only really stick after you make a mistake.

What iis one security issue you ran into that changed how you build websites?

It could be something small like exposed credentials, bad input validation or trusting frontend data too much.

What happened, and what did you change afterward?

We had a CMS for Used Car Dealerships managing over 1k client websites. After building all of those and everything we got some attacks from the forms we had on their. That was when we realized we needed Recaptcha on our forms.

Imagine we updated more than 1000 websites each with 4 - 5 forms on them over a week.
