ZScaler Certificate Installation Instructions

ZScaler is the Internet content filtering solution used in the Stokes County School District for all users accessing the Internet inside our District or from District owned devices, used off-site. All users are required to authenticate to the content filter system to gain access to the Internet. Guest Presenters to the Stokes County School District may obtain a day-use username and password from the Technology Department, upon request. Please see your site Media Coordinator or Principal to submit guest access request.

Domain Joined Devices (Windows Desktop & Laptop computers) owned by Stokes County School District

NO USER ACTION NEEDED FOR DOMAIN JOINED DEVICES. Your ZScaler certificate and authentication cookie will automatically push down to your workstation, when you log into the CO domain. This is an automated process that occur's at login. You will NOT need to manually install the certificate to any District owned, domain joined computer. You will be prompted to login to the ZScaler login screen the first time you access the Internet, only once, from each new computer that you login to.

You will login to ZScaler using your Stokes County Domain user credentials as follows: firstname.lastname@stokes.k12.nc.us

When prompted for your password, you will enter the domain password (password that you use to login to the network at your school).

Personally Owned Devices

Personally owned devices are also required to authenticate to the ZScaler Content Filter, to gain access to the Internet. Users will be required to download and install the ZScaler root security certificate. This certificate is installed so that your Internet traffic can be securely transmitted. No data is collected from your computer, and no software or off-site monitoring capabilities are ever installed on personally-owned devices.

Before you install the certificate, you will need to download it to your computer. If you are using a Windows or Mac computer, save the file to your Desktop so that you'll be able to locate it later. Please refer to the installation instructions below, depending on your OS platform.
