The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

The solution has a single price for unlimited assets. Value wise, the solution is also great for pen testers and consultants. The solution is useful for vulnerability and patch management from both the internal and public facing sides. Quick assessments, compliance scores, and results are provided without having to do agents.

Tenable Nessus could include a broader range of IT assets. Nowadays, IT is not limited to laptops and desktops. It can be any environment in the organization, such as iOS or Android mobile phones. Apart from that, organizations use APIs and specific tools. We would like Tenable to cover every aspect of IT infrastructure, not just generic systems like laptops, desktops, switches, or servers. It should include every kind of device, like Raspberry Pi. This small chunk of devices acts as sensors in several organizations. We would like to be able to scan every device in the network, and the solution should present vulnerabilities within their system.
