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.
NaySan @ Suraj Verma - PeerSpot reviewer
Provides actionable vulnerability insights and recommendations with notable efficiency
They may need to improve the portal refresh rate for Microsoft Defender Vulnerability Management because it takes time for recommendations to disappear after mitigation; sometimes, it takes one week, when it should ideally take only one to two hours. Overall, everything is good with Microsoft Defender Vulnerability Management, but the portal refresh rate can take up to seven days in some cases and three or four days in others to reflect changes.
Mani Bommisetty - PeerSpot reviewer
Streamlines vulnerability management with excellent reporting and potential AI integration
Tenable is user-friendly and excels in reporting. It allows me to easily fetch and schedule reports. The software's discovery feature aids in strengthening our security posture. The single-sensor installation process on various operating systems is smooth, unlike Rapid7, which requires different versions for separate systems. Furthermore, Tenable enables vulnerability management through potential AI integration that consolidates efforts and resolves multiple vulnerabilities simultaneously.

Cons

"There is a good solution from Microsoft, however, there is a gap between Windows and Linux management."
"The worst aspect is the refresh rate of the dashboard."
"Integration can be improved."
