How to Add a Security Exception For Trusted Sites on Chrome

Security is perhaps the one biggest issue when it comes to browsing with chrome for mac and using the internet as a whole. That’s why there are tons of measures implemented to protect our most valuable data, including things like our passwords, login details, financial information, etc.

And one way of knowing whether you are about to visit a secure website is by having a look at the URL, which should contain the letters ‘https’. This tells your web browser that you are about to visit a secure website and that, in turn, prompts it to run a series of different checks to make sure that it is in fact secure. If for whatever reason the checks come back negative (e.g. the security certificate may have expired), your browser will display a warning before opening the respective page or site.

And basically the warning will be telling you that your sensitive information can be stolen if you proceed to the URL in question. And it is generally a good idea to heed this warning if this is the first time you are about to visit this web location.

But if you know for certain that you can trust this website, there is a way that you can visit it anyway and bypass the security error notification from your browser. Below is a guide on how you can do this.

What are the benefits of enabling trusted sites in Chrome ?

The way to dodge the error message displayed by your Chrome web browser for Mac when there’s an issue with the security certificate of a given site is by using the Trusted Sites feature. Here we would like to discuss the advantages of this feature and how you can use it to make the most of your browsing experience. It acts as an extra layer of protection on your mac from any malicious programs and extensions.

On the benefits of using trusted sites

The way the Trusted Sites feature in Chrome web browsers works is fairly simple. You pretty much add certain URLs to its list, in order to tell your browsing program that you trust said URLs. And once you visit a site like this, Chrome for Mac will skip doing the regular security checks that it normally does. Therefore, you will also notice that because of this, your trusted sites will load faster than others. Note also that plugins such as Java and Adobe Flash will automatically be enabled for your trusted sites. That is even if they are usually disabled by default for all other sites.

And there’s actually a very good reason for these specific plugins to be disabled by default, along with one called ActiveX. They have a history of causing issues and have been known to be a gateway for viruses and malware for years now. These plugins have rather serious weak spots in their security that can make it easy for Trojans, ransomware and other dangerous code to infect a given computer. Hence, in browsers like Chrome, Java and Flash are disabled by default as a security measure. Of course, you are free to change this configuration if you choose to. But it would mean putting your system at risk of malware attacks.

In cases, however, when there’s a specific website that you know to be trustworthy and that you visit often, manually having to enable these plugins can become tiresome. So it is for cases like these where the Trusted Sites feature can very much come in handy.

Once you add a website to the list, Chrome will automatically turn on all these plugins. As a result, the page will load quickly and very smoothly. But note that you won’t be receiving any permission requests for Cookies, as these will be accepted by your system automatically as well.


We strive to make our tutorials as helpful as possible. Your feedback is very important in helping us achieve this goal. Please let us know in the comment section what steps you find difficult and if you were successful in adding trusted sites to Chrome.
