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.
Ed Jarecki - PeerSpot reviewer
A scalable solution that helps to understand how infrastructure works
We use the tool as an infrastructure operational management solution.  The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization.  Any movement into a SaaS solution has challenges since the processes and data flows are not well…
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 saw benefits from Zafran Security almost immediately after deploying it."
"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 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."
"The interrogation piece was the most valuable feature because it was very detailed."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The security features are very valuable."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium’s linear-chain architecture is valuable."
"I would say Tanium is the best tool for vulnerability management."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"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."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"The initial setup of Tenable Nessus is very easy."
"The product's most valuable features are vulnerability and asset management. It can define the rules and validate the configuration."
"The most valuable features of Tenable Nessus include its ease of access and quick usability."
"Tenable integrates well with other solutions such as SIEM and batch management."
"Makes ransomware checking and OS auditing and implementation relatively easy."
"The trial version is very good for testing whether it will suit your needs."
 

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 needs to improve the reporting and tracking capabilities."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"The most painful thing is the interface. It's a bit unclear sometimes."
"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."
"The reporting could be improved."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"Tanium’s scalability could be improved."
"It would be nice for the professional module to include some of the reports available in the expert module."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"Model OS costs (and its segregation schema for individual modules)."
"I think the reporting templates could be improved with Tenable Nessus."
"Pricing is one of the most important features, and it is something that they can improve on."
"The product could have unique features similar to one of its competitors."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"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."
