Is data secure as long as you send it from/to an HTTPS page? I can still see form data in chrome's network devoloper tools

Question

The form was sent from https://www.numbersgate.com/batchpixel/signUp.php

I just want to know if all I have to do to ensure security is send from https to https.

Answer 1

https secures only the connection from the user to the server. Once they are at the server they are no longer protected by https against attacks, so you have to find others ways to protect them there. https will also not protect the data from against attacks against the logic of the web application, like CSRF, XSS, clickjacking etc. In short: https is just one part to secure the data, there is much more.
