Windows 10 recently started to display the following security alert when I start Unity 2017.1.0b10.
Any idea what is causing this? What is node.exe used for?

As the name implies NodeJS is a javascript run time environment. I don’t know what Unity specifically uses it for but it’s used for running scripts written in javascript, often for server type software. It’s also not new to 2017.1, previous versions of Unity use NodeJS too.
“Security alert” is a bit of an alarmist misrepresentation of what that dialog is for. It’s not alerting because of a security problem with the software doing something dodgy, NodeJS just wants network access and Windows Firewall is making sure it has permission to do so.
