VulnDetect is installed as service and is running silently in the background.
If you go to https://personal.vulndetect.com/#/applications and click on Configuration then you can set up when the automatic scan should start.
The scan results you see at https://personal.vulndetect.com/#/applications.
I am programming a small tool that offers a graphical UI and allows to start an immediate scan.
The tool is called Toolbox for VulnDetect and can be found here: https://1drv.ms/f/s!AsiLVok82IpQg_pe63xK8K01XuPIAw (in the folder "Toolbox Beta).
But I am a normal user, not an official of SecTeer (the programmers of VulnDetect) so use the tool at your own risk!
