Your security is one of the most important things while browsing the Internet. However, sometimes there might be some issues that can cause Your connection is not secure message to appear. This message can prevent you from accessing your favorite websites, so today we’re going to show you how to fix it on Windows 10.

If you’ve ever visited a website and been confronted with a message stating “This site is not secure,” or "Your connection is not secure," there are some simple methods for diagnosing the problem, gauging your level of risk, and mitigating any potential security hazards.

What Does 'Connection is Not Secure' Mean?
When your browser flags a website as being not secure or insecure, it has detected a problem with the Secure Socket Layer (SSL) certificate that certifies the identity of the site. You might hear these certificates referred to as TLS certificates, but for the purposes of this, we'll refer to this mechanism as an SSL certificate (or simply a certificate).

While SSL certificates use the principles of encryption to perform this identity verification, and SSL is a full-fledged encryption protocol, SSL certificates aren’t technically the encrypted connection itself. Indeed, it's technically possible for your computer to establish an encrypted connection to a malicious site posing as a legitimate site.

Your browser only understands encryption by means of the SSL certificates, so if the site has a valid certificate then it encrypts its connection to that site. However, if the site’s certificate is invalid or missing, it does not establish an encrypted connection. Basically, every site that has an SSL certificate also employs SSL encryption, so they go hand-in-hand.
