“This Connection Is Not Private” – What it Means and How to Protect Your Privacy

Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.   

What does “this connection is not private” mean?

A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.  

So, what exactly is going on when you see the “this connection is not private” error?  

For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate. 

Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.  

In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.  

While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.   

SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL. 

So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.  

Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.   

How to fix the “connection is not private” error

If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.  

• Refresh the page. In some cases, the error is just a momentary glitch. Try reloading the page to rule out a temporary error.  
• Close browser and reopen. Closing and reopening your web browser might also help clear a temporary glitch.  
• If you’re on public WiFi, think twice. Hackers often exploit public WiFi because their routers are usually not as secure or well-maintained for security. Some public WiFi networks may not have an SSL connection, or they may limit your access to websites. You can safely browse more securely in public spaces if you have an antivirus software or virtual private network (VPN) solution. 
• Use “Incognito” mode. The most used browsers (Google Chrome browser, Mac‘s Safari, Mozilla Firefox, and Microsoft Edge) offer an “Incognito mode” that lets you browse without data collecting in your history or cache. Open the site in a new incognito window and see if the error still appears.  
• Clear the cache on your browser. While cookies make browsing the web more convenient and personalized, they also can hold on to sensitive information. Hackers will take advantage of cached data to try and get passwords, purchase information, and anything else they can exploit. Clear browsing data before going to a site with the “connection is not secure” error to help limit available data for hackers.  
• Check the computer’s date and time. If you frequently see the “connection is not private” error, you should check and ensure your computer has the accurate time and date. Your computer’s clock can sometimes have time and date stamp issues and get glitchy in multiple ways. If it’s incorrect, adjust the date and set the time to the correct settings.  
• Check your antivirus software. If your antivirus software is sensitive, you may have to disable it momentarily to bypass the error. Antivirus software protects you, so you should be careful to remember to turn the software back on again after you’ve bypassed the error.  
• Be sure your browsers and operating systems are up to date. You should always keep your critical software and the operating system fully updated. An outdated browser can start getting buggy and can increase the occurrence of this kind of error.  
• Research the website. Do a quick search for the company of the website you wish to visit and make sure they are a legitimate business. You can search for reviews, Better Business Bureau ratings, or check for forums to see if others are having the same issue. Be sure you are spelling the website address correctly and that you have the correct URL for the site. Hackers can take advantage of misspellings or alternative URLs to try and snare users looking for trusted brands. 
• If it’s not you, it’s them. If you’ve tried all the troubleshooting techniques above and you still see the error, the problem is likely coming from the site itself. If you’re willing to take your chances (after clearing your browser’s cache), you can click the option to “proceed to the domain,” though it is not recommended. You may have to choose “advanced settings” and click again to visit the site.   

Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.  

How to protect your privacy when browsing online

Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.  

• Antivirus solutions are, hands down, your best line of protection against hacking. Solutions like McAfee+ Ultimate offer all the tools you need to secure your data and devices.  
• Use strong passwords and two-factor authentication when available. 
• Delete unused browser extensions (or phone apps) to reduce access. 
• Always keep your operating system and browsers up-to-date. You can open system preferences and choose to update your system automatically. 
• Use a secure VPN solution to shield your data when browsing. 
• Use your favorite browser’s incognito mode to reduce the data connected to your devices. 
• Remove any 3rd party apps from your social media accounts — especially if you’ve recently taken a Facebook quiz or similar (also, don’t take Facebook quizzes). 
• Engage the highest privacy settings in each of your browsers. 
• Always check the address bar for HTTPS before sharing credit cards or other sensitive data on a website. 
• Share less personal and private information on social media.
