Nessus - Proprietary & GPL?


I was studying for a security certification, and I came across Nessus, which is a vulnerability scanner. I looked it up on Wikipedia and found out that it's proprietary and yet it also uses the GPL.

What does this mean? Does it mean that the source code can be read but not modified? Or does it mean something else?

It can mean many things but in the case of Nessus the license was only GPL until version 2.2.x. So what that means is that you can use, modify, and redistribute the old versions under the GPL. That license change was many years ago and the world has moved on, mostly to OpenVAS. The new versions of Nessus are proprietary. OpenVAS is originally from the old version Nessus, but obviously has moved onward and forward. If you are looking to get started with a scanner try it instead.

Oh, okay. That's interesting. Thanks for the explanation!
