Hope you are doing well.
We are in plan to implement Vulnerability scanning tool, in our environment, go trough with the onsite content of OPENvas but i am having few question,
1 Is GSF (Greenbone security Feed ) also open source, if not then what will be the license cost?
2 Is GSF and GCF capable of sending alarm messages as per our set time?
We having small IP ranges around 50-100 , Our requirement is to make our system Vulnerable free and should get regular updates to make the system up-to-date and there should be some alarm feature which help us to know if any system is compromised.
