Cause of Your Connection Is Not Secure - You must have visited a website, but faced with the message "This site is not secure" or "Connection Is Not Secure". There are several ways to analyze problems, measure risks, and reduce threats or hazards. But what exactly is connection is not secure? When your browser marks a website as an insecure site, the browser actually detects a problem with SSL that validates the identity of the site.

The SSL certificate uses encryption to verify identity, SSL is also a complete encryption protocol, and SSL is technically not an encrypted connection. Unfortunately, it is technically possible for our computers to make encrypted connections to malicious sites that disguise themselves as legitimate sites. Your browser only understands encryption by using an SSL certificate. So if the site has a valid certificate, then it encrypts the connection with that site. But if the site's certificate is invalid or lost, it won't make the connection encrypted. Basically, every site that has an SSL certificate, also uses SSL encryption, so both ways go hand in hand.
Cause of Your Connection Is Not Secure
The cause of Your Connection is Not Secure
There are several reasons why a site might be listed as an insecure site. One possibility is that the site you visited has a certificate with the wrong configuration. SSL certificate settings are indeed difficult, especially if the site administrator has upgraded the SSL service, because not everyone does it right. Configuration errors can also occur when the server software is updated and potentially not synchronized. It could also be because the site administrator forgot to update the SSL certificate. These things are common because maintaining an SSL certificate is not an easy thing. The certificate also becomes invalid if the admin changes the site hosting provider or internet service provider. This change causes the new URL or IP Address to be incompatible, because it was not registered in the previous certificate.
Your Connection Is Not Secure
The errors that occur are not always the fault of the website manager. Browsers are indeed in line with certificates, but don't always synchronize with all the latest. So, if your browser is not the latest version, it could be what caused the copy of the certificate to disappear. The last possibility is that it is possible that the site you are heading to has never had a certificate. A reputable and trustworthy certificate requires a fee. All certificates also require technical knowledge. This is why some website managers choose not to question the certificate.

How to Identify Unsafe Websites
Most modern browsers consistently and explicitly identify unsafe sites.

Browser on the desktop
When a site has a problem like the one above, the browser will add the Not Secure tag at the left end of the navigation (where the URL is displayed), usually with a picture of an unlocked padlock. The picture of the padlock is accompanied by an information icon "i", or other gesture that describes the site as unsafe. Users can read the information by clicking the Not Secure tag. The information displayed is about the site itself and why the site does not meet browser security standards.

Browser on mobile
Because the design is concise and focuses on the efficient use of the screen, the browser on the cellphone does not usually display text. Your connection is not secure. They only rely on differentiation on the icon. Like a desktop browser, the browser on the cellphone shows a secure site with a locked green padlock. While for unsafe sites it is marked by an open padlock or an "i" information icon. Browsers on mobile phones can also display information about the site by clicking on the information icon.

How to Overcome Your Connection is Not Secure
  • Update browser. The easiest thing to do is to update the browser to the most recent version.
  • Use SSL checker. You can check by entering the URL into the SSL checker. SSL checker will tell you everything about the site. From the IP Address, the certificate issuer, to when the certificate ends. After the SSL checker returns the results, you can compare the information you get by clicking on the information icon on the website. If there is a difference between the two, you will find it difficult to identify the problem. But when both of them display the same information, the error will actually be a clue about how serious the problem is on the site.
  • Use HTTPS Everywhere. If the above checks reveal a simple problem, which actually has a valid certificate, you only need to take precautions before returning to browsing. For computers that use Firefox, Chrome, or Opera as browsers, you can install the HTTPS Everywhere extension to make sure all connections are encrypted. By installing the extension, if the certificate does not match, you still have an encrypted connection.
  • Avoid websites. If you have run everything but there is still an error, it could be a serious problem. You must be careful. Make sure you enter the URL correctly. If you have previously bookmarked, open the website from Bookmark then check if there is a tag Your connection is not secure (Not Secure). If these tags exist, don't visit the site for a while. Let the website manager solve the problem.
Don't log in to the website
There are several reasons why a site might be listed as an insecure site. Your connection is not secure can occur because of the SSL certificate settings that are having problems. The browser will warn you if the website is indeed an insecure site. So it's better not to open the website for a while. Look for sites that are truly safe so that sensitive data remains protected.
