Featured Reviews

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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

Quotes from Members

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

Pros

"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"You can then direct your team to create a report on the discovered vulnerabilities."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"The most valuable feature of Tenable Nessus is vulnerability detection."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
"The most valuable feature of Tenable Nessus is website scanning."
"I like this solution because it is complete. It can scan and check many types of vulnerabilities. It can also check for compliance."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"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."
"Zafran is an excellent tool."
 

Cons

"The solution could improve security updates."
"Scans aren't done properly and some devices aren't pinged."
"In terms of what could be improved, I would say its reporting portion."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"The scalability of Tenable Nessus is good. However, it could be more flexible."
"I have found it is sometimes difficult to control the Zoom meeting sessions. For example, it is difficult to know who is talking and when trying to mute everyone but the speaker you end up muting everyone. When using multiple screens it is laborious to find the control buttons, such as to start a session. Additionally, when a recording is done I have found it difficult to find them, there should be an easier way to retrieve them."
"The reporting feature needs to be improved."
"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."
"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."
 

Pricing and Cost Advice

"I would like to see better discounts."
"In general, it is extremely expensive."
"The solution has a single price for unlimited assets."
"We pay approximately $2,500 on a yearly basis."
"Cost-wise, it's an affordable tool."
"It has a fair cost and very good cost-benefit ratio."
"The solution is worth the cost. It's a good investment."
"The price of Tenable Nessus is too expensive for each service center."
