If you’ve recently browsed on-line, you’ll have no doubt come across warning messages such as ‘NOT SECURE’ on some of the sites you have visited. This is becoming more and more prevalent as the search engines such as Google strive to highlight the websites it deems as unsafe.
In essence, any interaction between visitor and website should be secure in order to protect the data from third party interference. Ensuring the domain name is prefixed https: (Hyper text transfer protocol secure) and having the green padlock device offers this protection and reassures users the website is secure.
Mozilla Firefox, Opera, Edge all have introduced their warnings on non HTTPS site, and whilst Google and other lagre search engine won’t penalise you, potentially these warnings will scare people away from your site.
