If you get a certificate error or connection is not private error message when trying to access certain websites like Blackboard, your device's operating system and/or browser is out of date. You need to upgrade your operating system (OS) and/or web browser (see below for a list of OSs and web browsers that need to be updated).
If you can't upgrade but need to access the service now, you can use the Virtual SINC Site. See Stony Brook's Hardware page for new device recommendations.
