How to know if a website is reliable

Currently it is hard to trust an unknown website and much more if we are going to use personal data, in this case I propose a utility offered by SSLlabs laboratories that have different way of verifying how reliable a website can be, the most used is the option to check in real time how trustworthy is a website address and what category of security it has (for example the banks should be classified in the A) I attach some screenshots to show you some examples. You can also check the vulnerability of browsers.
Very reliable this Laboratory (SSLabs), it is grateful to be able to use these tools.
