Web Filter & Certificate

As of School Year 2025-2026, Dwight-Englewood School is using a new Internet filter for campus Wi-Fi.  When visiting a blocked web site, you will see a notification page letting you know that the page is blocked and what category the web page falls into.

Note that in order to see the block notification page, you will need to install a security certificate for our web filter.  For employee devices and for student devices purchased through the school, the certificate is already installed.  For personal devices or students with bring-your-own-device, you will need to install the certificate.

If you do not install the certificate, when visiting blocked web sites, you will see a Certificate or Privacy Warning error in your web browser.
