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.
MohammedJaffir - PeerSpot reviewer
Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

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."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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 saw benefits from Zafran Security almost immediately after deploying it."
"The solution is very easy to use."
"The most valuable feature of Tenable Nessus is the dashboard. They are convenient to use."
"The scanning and reporting features are the most valuable aspects of Tenable Nessus."
"The solution can scale well."
"Tenable integrates well with other solutions such as SIEM and batch management."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The plug-in text information is quite useful."
"It gives you an unlimited IP scan."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
 

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."
"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."
"The reports must be more specific to help us understand what we should do to mitigate the problem."
"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."
"Consumes more system resources when it's running."
"The report for counters is too simple and would be improved by a dashboard."
"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."
"The features are limited when it comes to scanning network devices for vulnerabilities."
"The reporting feature needs to be improved."
"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."
"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."
 

Pricing and Cost Advice

Information not available
"The product is free."
"Cost-wise, it's an affordable tool."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"The solution has a single price for unlimited assets."
"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"The product is free."
"The solution has free options."
"I would like to see better discounts."
