Possible disadvantages of Nessus

Despite its user-friendly interface, fully leveraging all of Nessus's advanced features and capabilities can require a significant learning curve.
Limited Free Version
The free version of Nessus, Nessus Essentials, is limited in its capabilities and is intended for individual use or small networks, which may not be sufficient for larger organizations.
