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.
NitinKushwaha - PeerSpot reviewer
Stable product with an ability to build complex roles
We use Tanium as an EDR solution for managing end-user devices and servers The product is granular and can build complex roles compared to other EDR vendors. Tanium's dashboard UI could be similar to CrowdStrike. We have been using Tanium for two and a half years. The product is stable. I rate…
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"I would say Tanium is the best tool for vulnerability management."
"Tanium's most valuable feature is its instant discovery aspect."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"The interrogation piece was the most valuable feature because it was very detailed."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"The security features are very valuable."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"Tenable Nessus streamlines the process of scanning for our organization."
"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."
"The automatic scanner and scheduler are pretty cool."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"The features I personally like include host discovery."
"The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing."
 

Cons

"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 dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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 solution lacks mobility."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"The reporting could be improved."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"The solution should be able to support more devices."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"Remediation needs improvement."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"We feel the solution's technical support to be very bad."
"They should improve the I/O reporting and the customized spreadsheet export feature."
