There is no more Nessus Home edition, as of May 2019, Nessus Home will be called Nessus Essentials. Whenever you see or hear the Nessus Home in the videos, know that this is the Nessus Essentials.
Nessus Home allows you to scan your personal home network (up to 16 IP addresses per scanner) only. It is not for use by any commercial organization. In Nessus Home, you can only scan the private IP address space which is specified in the RFC1918.
Private address spaces are shown below.
10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (prefix 172.16 / 12)
192.168.0.0 - 192.168.255.255 (192.168 / 16 prefix)
Nessus Essentials allows you to scan your environment (up to 16 IP addresses per scanner). Nessus Essentials eliminates the previous restriction on only using Nessus Home for personal, non-commercial use. You can scan real IP addresses too
With Nessus Essentials, vulnerability scans can be performed without private address space (RFC1918) and time limit constraints.
Although Nessus Home is used in this course, you can use the current Nessus Essentials version for vulnerability scans.
