Hi,
I used the Full and Fast scan for a XP machine ( vunlerable ) and I scanned with Nessus and Openvas. I wasn’t able to find ALL vulnerability that Nessus found but the big issue is the authentificate scan. When I entered the login in nessus I was able to find 700+ vuln. but with Openvas I wasn’t able to find any new compare to the non-authentificate one. I added the credential in the target in SMB, SSH, still no success. All my feeds are up to date.
Thank you
