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.
MB
Enhanced endpoint security with effective patch management and frequent scans
The most valuable feature was the patch management, which was very effective for endpoint-centric solutions requiring remediation of vulnerabilities. ManageEngine Vulnerability Manager Plus was the perfect fit for managing these requirements. We improved the number of scans and patches performed from four times per year per computer to four times per month.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We saw benefits from Zafran Security almost immediately after deploying it."
"ManageEngine is a comprehensive tool that is broad and can be customized to fit specific needs."
"The most valuable feature was the patch management, which was very effective for endpoint-centric solutions requiring remediation of vulnerabilities."
"I have been using it for over two years, and it is fantastic."
"The solution helps us figure out vulnerabilities and fix them."
"The most valuable feature was the patch management, which was very effective for endpoint-centric solutions requiring remediation of vulnerabilities."
"The solution can scale well."
"I like the fact that it was not expensive. I like that it's user-friendly."
"I find the features that are most valuable are the policies that help us identify the vulnerabilities. These policies are then used for scanning instabilities and then identifying the particular vulnerabilities."
"The solution is great for scanning servers."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"Once you get past the initial implementation, the solution is very stable."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
 

Cons

"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."
"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."
"The integration with third-party solutions such as ticketing solutions or CMDB solutions can be improved."
"One area that needs improvement is the contract management. My legal team required some partner requirements for that, and ManageEngine could not support it."
"The user interface is the only drawback of the product."
"The integration with third-party solutions such as ticketing solutions or CMDB solutions can be improved."
"One area that needs improvement is the contract management. My legal team required some partner requirements for that, and ManageEngine could not support it."
"They need more flexible pricing."
"The integration part is not good because five years ago, Tenable Nessus had more integration capability. After that, Tenable changed their policies and strategy."
"The pricing point has increased significantly in recent years. The product's pricing has roughly tripled within the last couple of years, making us reconsider renewing the license for the scanner."
"Tenable Nessus could improve the reporting."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"Online learning could be a bit better."
