How to install the Securly SSL Certificates on Chromebooks and Chromeboxes


You would want to install the Securly SSL certificate in your Chrome browser to ensure the best browsing experience. The certificate does not control the level of filtering or what sites are allowed. The certificate will prevent errors on sites that Securly decrypts. Without the certificate, sites like and will show privacy errors, users will perceive this as the internet being “broken”.    

To install the Securly SSL certificate manually in Chrome, open ‘chrome://settings’ in your Chrome browser (version 59.0.3071 and above)

Installing on Chromebook (ChromeOS)

  1. Download the Securly certificate. 
    • Later this Fall, Securly's current SSL Certificate will expire. We have provisioned a brand new SSL Certificate available below which expires in 2034. While to get up and running today you only need to have the original SSL Certificate Installed, we recommend that you install both SSL Certificates at the same time to ensure when the original expires, you are at no loss of service.
