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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
AH
Deploying autonomous security tools improves network protection and efficiency
One of the areas where improvement is needed is in the visibility and reporting for large enterprises. The existing GUI or NodeZero insights provide better visibility, but there's still room for enhancement. Moreover, there is a need to automate interactions with other systems, particularly in triggering or opening tickets in ServiceNow ( /products/servicenow-reviews ). Adding the application layer would also be valuable for clients.

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."

"Remediation needs improvement."

"The accuracy of the vulnerability assessment is not up to par yet, as false alarms and false positives occur often."
"The price and scalability of the solution could improve."
"The problems I faced with Tenable Nessus were related to its dashboard's customization capabilities and its ability to provide data to third-party sources."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"Tenable Nessus could include a broader range of IT assets."
"The reports are quite useless."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
