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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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 is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Tanium's most valuable feature is its instant discovery aspect."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"I like the tool's incident response and security patching."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"The product is granular and can build complex roles compared to other EDR vendors."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"I like this solution because it is complete. It can scan and check many types of vulnerabilities. It can also check for compliance."
"The scanning capabilities are most valuable when compared to Nessus."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully."
"It allows me to prioritize efforts and utilize effective technical resources."
"The plug-in text information is quite useful."
"It gives you an unlimited IP scan."
"The vulnerability scanner is the most valuable feature."
 

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."
"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."
"They could improve the UI."
"The reporting could be improved."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"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."
"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 limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"The most painful thing is the interface. It's a bit unclear sometimes."
"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."
"They need more flexible pricing."
"In terms of what could be improved, I would say its reporting portion."
"The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have."
"The product could have unique features similar to one of its competitors."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings."
"They should improve the I/O reporting and the customized spreadsheet export feature."

"In general, it is extremely expensive."
