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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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 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."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran is an excellent tool."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Security is the key number because it can start to scan with a few clicks instead of credits, which is a bit complicated. So simplicity is the first advantage. Then the generated reports are well done and easy to present to management. The quality of the scan is quite good in detecting the severity. The solution has simplicity. Also, it has frequent updates so that is also a valuable feature."
"Tenable Nessus is cheap and flexible."
"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."
"It's scalable."
"I like the fact that it was not expensive. I like that it's user-friendly."
"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."
"The vulnerability scanner is the most valuable feature."
"Tenable Nessus has a good performance, is very user-friendly, and is easy to use."
"Vulcan Cyber offers a single pane of glass for centralizing our security data."
"Vulcan Cyber is a very good tool."
"It is very good when it comes to ingesting information from different sources and then displaying this information in an easy-to-use platform."
"I was part of the initial deployment. It was pretty easy. To fully deploy, it took about three or four weeks."
"Vulcan enables us to automate tickets from multiple scanners. It has lots of analytics options that show us charts and allow us to view the statuses in different waves. The dashboard is nice because it's highly informative about the big picture."
"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."
"Vulcan Cyber has helped reduce our organization’s mean time to remediation."
"I find the ability to consolidate information from multiple vulnerability scanners into a single source valuable."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"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 price and scalability of the solution could improve."
"We feel the solution's technical support to be very bad."
"Scans aren't done properly and some devices aren't pinged."
"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."
"The reporting feature needs to be improved."
"The user interface of Tenable Nessus feels outdated and could be more user-friendly."
"Tenable Nessus could improve the price."
"It would be nice for the professional module to include some of the reports available in the expert module."
"Their support is good, but there are some flaws as well."
"We've faced situations where we required support on a Friday, and support wasn't available."
"Improvements are needed in providing more concise details on how to apply remedies for particular vulnerabilities."
"If there was a way for me to connect to the vendor directly from the application, it would be helpful."
"The product helps, but the reporting relies heavily on Power BI. It is limited to graphical views and requires additional filtering, posing operational challenges."
"Mainly, what I would like from them is more maintenance of the different connectors they have in the platform."
"I would rate the tool between six and seven because there have been instances when the tool was down, and I couldn't access Cyber reports. Additionally, the Vulcan Cyber team made changes to the tool and did not notify us."
"It would be extremely helpful to have a community group around the product."
 

Pricing and Cost Advice

Information not available
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"When comparing the price of Tenable Nessus to other similar solutions, such as Acunetix, Tenable Nessus is not as expensive. It is averagely priced in the market. We pay for the solution annually."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"The solution is worth the cost. It's a good investment."
"Our organization is huge so our license costs $30,000."
"The price of the solution is reasonable."
"The price is reasonable."
"While Tenable Nessus is a good enterprise solution, the high price would likely make it prohibitive to smaller organizations."
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
"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."
