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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"I would say Tanium is the best tool for vulnerability management."
"I like the tool's incident response and security patching."
"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."
"The product is granular and can build complex roles compared to other EDR vendors."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"Tanium's most valuable feature is its instant discovery aspect."
"Tanium’s linear-chain architecture is valuable."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"The plug-in text information is quite useful."
"The most valuable feature of Tenable Nessus is real-time monitoring."
"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."
"Tenable integrates well with other solutions such as SIEM and batch management."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
 

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."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"They could improve the UI."
"The solution can give a lot of false positives."
"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."
"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."
"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 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."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"Pricing is one of the most important features, and it is something that they can improve on."
"You can scale Nessus to the extent that you can afford it. You need to have a license for every device you scan. As long as you can afford the increased costs, you won't have a problem scaling it."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"We'd like to see more integration potential within the solution."
"From my point of view the solution basically is not for the big enterprise."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"In terms of what could be improved, I would say its reporting portion."
"Remediation needs improvement."
