- The website is compromised and there is a malicious redirection.
The options you have are:
- Close the tab and do not visit the site
- Go on to the webpage, which is not the recommended option, and be careful not to enter any information. Also, make sure that your security software is working fine.
You could try another thing:
- Clear your browser cache and try again
- Check using another browser.
So if you trust the website, then you may proceed to visit the site. But if you have doubts or are unsure, it is best to close the tab and avoid visiting the webpage.
If you receive this error frequently on your favorite website, you could contact its administrators and ask them to look into this matter.
Administrators may want to check if your network is behind a Proxy. Also, check if the Certificates are renewed and propagated correctly.
Is it safe to go to a website that says Not Secure?
Visiting a website labeled “Not Secure” can be risky, as it lacks HTTPS encryption. This vulnerability exposes your data, making personal information such as passwords or payment details susceptible to interception by hackers, compromising your online safety. Always exercise caution and prioritize secure HTTPS connections when browsing.
How do I turn off This site that is not secure?
To stop seeing the “This site is not secure” warning, open Chrome on your computer. Navigate to Settings, then Security. Under “Safe Browsing,” select the “No protection” option. Note that this is not recommended as it may expose your device to security risks and potential threats.
