Featured Reviews

SimonClark - PeerSpot reviewer
Able to discover unpatched servers, offers good stability, and scales very well
A low-cost service to evaluate the risk score of a supply chain would be very helpful. This could be useful for insurance companies offering cyber insurance to enterprise customers, providing the insurer with a valuable way to unobtrusively, quickly, and frequently assess their customers and apply appropriate premiums for the level of risk. This would also be useful for enterprises. They could, for example, assess companies prior to a merger or acquisition. What would also be useful for any enterprise would be if their supply chain has some kind of direct digital access to parts of their network.
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
