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.
César Ibáñez - PeerSpot reviewer
A highly scalable and easy-to-use solution that helps identify vulnerabilities
The time taken for a scan is too long. I tried to scan a website, and it took me ten hours. The report was sent to me two days later. The reports must be more specific to help us understand what we should do to mitigate the problem. There is not a lot of documentation on how to manage all the features of the product.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"Zafran is an excellent tool."
"The solution is very easy to use."
"The most valuable features are that it's fast, it's easy to use and it provides good reports."
"Its initial setup was simple and straightforward."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
"Tenable Nessus is cheap and flexible."
"Quick assessments, compliance scores, and results are provided without having to do agents."
"The support has been really cooperative."
"The most valuable feature is the installation of Tenable which is incredibly easy."
"The solution can scale well."
 

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."
"The reports must be more specific to help us understand what we should do to mitigate the problem."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"The report for counters is too simple and would be improved by a dashboard."
"They should try to create an all-in-one solution."
"There is room, overall, for improvement in the way it groups the workstations and the way it detects, when the vulnerability is scanned. Even when we would run a new scan, if it was an already existing vulnerability, it wouldn't put a new date on it."
"Technically, it is an excellent and the best solution available in Libya. My only concern is related to its pricing. They are an emerging company in Libya, and they need to put in some effort to provide us with very good prices so that customers can go with the best solution. Chinese companies are getting into the market here, and they're providing very cheap solutions."
"Model OS costs (and its segregation schema for individual modules)."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
