Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
César Ibáñez - PeerSpot reviewer
A highly scalable and easy-to-use solution that helps identify vulnerabilities
The time taken for a scan is too long. I tried to scan a website, and it took me ten hours. The report was sent to me two days later. The reports must be more specific to help us understand what we should do to mitigate the problem. There is not a lot of documentation on how to manage all the features of the product.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
