OpenVAS is a framework of several services and tools offering a comprehensive and powerful vulnerability scanning and vulnerability management solution.
It is a pretty neat tool to check your network for vulnerabilities. I wanted to download their demo OVA but it took ages to download. So I threw it up on my google drive for later. Today I saw it on my drive and thought I would share it if anyone else needed a faster download. I think it was originally hosted in Germany.
This is the page I downloaded it from: http://www.openvas.org/vm.html
Here is the Google Drive link: OpenVAS-8-DEMO-1.0.ova
There are checksums so on openvas.org so you can verify the download.
