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.
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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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.
Shreevinayak Deshpande - PeerSpot reviewer
Makes vulnerability management efficient with a single pane of glass and daily report generation
There are areas for improvement. Initially, when onboarding Vulcan Cyber, the setup and configuration was more complex than expected with a user-friendly approach. This aspect can be enhanced. An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports. The team might have to work on scaling up servers. When we click on a vulnerability, it takes ten seconds to pop up a window and show the entire content. Instead of that, they can put a down arrow, and all the details should be shown on clicking the arrow. This will prevent that ten-second delay. Another area for improvement is providing support and documentation for their tool. Users should have access to easy-to-understand trial documentation for reference.

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."
"The solution can scale well."
"Nessus gives me a good preview of vulnerabilities and good suggestions for remediation. It's easy to find a description of a given vulnerability and solutions for it."
"It gives a holistic view of your entire environment."
"Among the most valuable features are scanning for vulnerabilities and the reporting. The reporting templates are okay. I like that I can see all the hosts with different vulnerabilities."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"Tenable Nessus is cheap and flexible."
"The automatic scanner and scheduler are pretty cool."
"I have found the vulnerability assessment and the reports to be useful."
"The interface of Vulcan Cyber is intuitive with a lot of information about vulnerabilities, which helps in classifying and analyzing threats."
"The interface of Vulcan Cyber is intuitive with a lot of information about vulnerabilities, which helps in classifying and analyzing threats. We have a good view of assets and vulnerabilities. It helps to do good threat analysis because we can see exactly what the threat is and assess it accordingly."
"One of the features that I find valuable is the ability to bifurcate the report according to the many options available."
"I find the ability to consolidate information from multiple vulnerability scanners into a single source valuable."
"Now that the solution is onboarded, we are saving a lot of time. We're saving roughly four to ten hours a week."
"Vulcan Cyber helps us prioritize the vulnerabilities that are really exploitable and our point of interest for the industry based on the threat intelligence that we get."
"Out of the three solutions I've used, Vulcan Cyber is the superior option."
"The automation capabilities using the Vulcan API platform or the API feature allow me to easily automate scripts and reports and schedule them."
 

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 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."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"Vulnerability recommendations are outdated and not in line with industry standards."
"The reporting is a bit cumbersome."
"The reports should be improved in Tenable Nessus. For example, when you are auditing compliance with CIS standards. It provides very poor reports."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"The inventory management function in this solution needs improvement."
"The reports are okay, but the interface is a bit difficult to navigate in some cases."
"Monitoring of the evolution of campaigns and perhaps having more customized options for monitoring them would be great."
"It would be extremely helpful to have a community group around the product."
"The performance is bad. The query and the UI are always slow, and it's quite frustrating. Vulcan is trying to solve this with a newer design. The dashboard is also crowded. It pulls in all this raw information that you need to filter. Vulcan has filtering capabilities, but they're hard to manage. The labels aren't very clear, so you need to do things by trial and error. It's not as easy as other tools we've been using."
"An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports."
"The fact that we cannot use it for our reporting leads me to rate it three out of ten."
"Mainly, what I would like from them is more maintenance of the different connectors they have in the platform."
"Improvements are needed in providing more concise details on how to apply remedies for particular vulnerabilities."
"There are several areas needing improvement. The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges."
 

Pricing and Cost Advice

Information not available
"The price of Tenable Nessus could improve, it is expensive."
"This solution is affordable."
"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 price of the solution is reasonable."
"Nessus is affordable, but its licensing model could be improved with more flexibility for adding assets."
"We paid about six thousand dollars per license."
"The price of Tenable Nessus is too expensive for each service center."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"Its pricing is quite fair compared to what is out there in the market, especially compared to the tool from Microsoft. It is a SaaS platform that has an annual cost, so it is something that is already used by many companies. It is quite affordable."
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
