GlobalProtect Logo With Virtual Private Network (VPN), staff and students can make secure connection from their home computers or mobile devices to the campus network over the Internet. Data transmitted via VPN connection are encrypted. Users can access certain restricted IT services such as DMS, use SPSS and make connection to some central network servers using SFTP client software outside the campus.

The “Palo Alto GlobalProtect” technology (GlobalProtect VPN) was launched in September 2014. The GlobalProtect VPN requires users to install the GlobalProtect software on their device(s). It then establishes a virtual tunnel to the campus network with authentication using the user’s EdUHK network account and password. For security reasons, the GlobalProtect VPN client software should NOT be used on public computers. Please install and use the software only on computers protected with up-to-date anti-virus software and firewall protection.

Tips and best practice on using GlobalProtect VPN


  1. The VPN connection is based on the Internet connection of your device to set up a tunnel back to HK. User are recommended to use a fast and reliable connection to enjoy good VPN experience. After the VPN is connected, you could test the network speed by using "" which could measure the network throughout. Anything over 10Mbps is good.
