Extended Validation Certificate

An extended validation (EV) certificate is a type of website security certificate, like a locked door on a building. It helps to make a website more secure by making sure that it is legitimate and not pretending to be something that it isn't. An EV certificate is special because it requires more steps and higher levels of scrutiny compared to other types of website certificates, so it helps you know that the website is safe to use.
