Securly offers different filtering solutions depending on the device you use. The Securly Chrome Extension is the preferred method of filtering Chrome OS (Chromebooks / Chromeboxes). It is offered free of cost to K-12 schools across the world.
The Securly Chrome extension is a user based extension that is deployed via the G Suite Admin console. When a user logs into a Chrome browser on Windows, OS X, or into a Chrome OS device they will get the Securly Chrome Filtering Extension, but it will not filter or log traffic. The extension is only active on Chrome OS. The extension works kind of like an ad blocker and blocks entire websites directly on the device. It uses the Google filtering API directly on the device to view the traffic. This provides a deep level of inspection for the traffic without any Man in the Middle (MITM) decryption. If you are using Securly DNS filtering solution in conjunction with the Chrome Extension filter, the SSL certificate should be deployed to G-Suite.
The extension requires that the user is logged into the device with a registered school domain. If a domain is not found, the extension will be deactivated and allow all traffic to pass without filtering or logging. Note: Ensure that you have signed up for a Securly account and have all domains registered before deploying the Securly Chrome extension.
All Securly filtering solutions use unified policies set in the Securly UI. The school admin creates and assigns policies to users and OUs via the Securly Admin UI. Settings in the Securly user interface do not enable filtering. Policies and filtering only affect users with the Securly Chrome extension enabled. When traffic is passed through the Securly extension for filtering it calls out to the Securly server and checks if the site is allowed or blocked. It checks other parameters applicable to the user as per the policy assigned to him and displays or blocks the site accordingly. The user’s activity is logged by the Securly server and displayed to the school admin via the Securly Admin UI.
The Chrome extension will usually work with onsite proxy-based filtering solutions because Securly works directly on the device at a different level. Note that if you have another filtering solution that also uses a Chrome extension to filter, it can conflict with the Securly solution.
