To ensure your device and connection is secure you should install the certificates onto your device. If you have a Windows Vista, 7 or 8 PC, Mac Lion or Mountain Lion PC, Apple IOS device or Linux device you can visit the CAT eduroam and install all certificates AND set up the wireless networks automatically for PHOENIX-NET-FAST, PHOENIX-NET-SECURE and eduroam.
If your devices are not listed on the CAT eduroam site, then you can download and manually install the certificates directly onto your device from the links below. You will likely need to install all 5 certificates and if prompted, the ROOT CA certificate is the AddTrust certificate. Manual installation of certificates varies by device, so you should follow the instruction from the user guide of your own device. You should ensure that you enforce the checking of the certificates.
