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.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
Chee Young Tan - PeerSpot reviewer
Has a valuable feature for attack simulation; it highlights the vulnerability and offers recommendations for improvement
XM Cyber helps identify risk by creating a shadow environment mirroring the production system. While it doesn't directly mitigate risks, it simulates attacks across this replica, uncovering vulnerabilities and weak points within the system. Once a WISC is established, it highlights the vulnerability and offers recommendations for improvement. It provides reporting templates, making the process faster. I rate it an eight out of ten.
