How to install Securly SSL certificate in Internet Explorer?

You will need to install the Securly SSL certificate on your device to ensure that Securly is able to filter all HTTPS sites browsed there effectively.

To manually install the Securly SSL certificate:

1. Open a new Internet Explorer window and navigate to Tools > Internet Options.

Note that depending on the version of Internet Explorer, Tools can be at the top or at the top right.

2. In the new window that appears, click on the Content tab at the top in the middle of the other tabs.
3. Click on the Certificates button near the middle of the window.

4. Another window appears. In this window, you can see all the certificates currently on your machine. This list of certificates also includes what is trusted by Internet Explorer.
5. Click on the Trusted Root Certification Authority tab and click Import.
6. Upload the certificate attached at the end of this article. 

Trusted Root Certification Authorities - These are the Root Certificates that Internet Explorer trusts. Any personal certificate that falls underneath any of these roots will be trusted (unless the certificate is revoked or expired).

Note that Microsoft stopped developing the Mac OS X version of IE after 5.2.3, which won't run on 10.7 or higher. Microsoft never created an IE version for iOS devices. 

You can also run the "Securly SSL Windows.exe" file attached at the end of this article to automate the process.
