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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran is an excellent tool."
"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."
"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"You can then direct your team to create a report on the discovered vulnerabilities."
"Tenable Nessus streamlines the process of scanning for our organization."
"The most valuable feature of Tenable Nessus is website scanning."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device."
"I was part of the initial deployment. It was pretty easy. To fully deploy, it took about three or four weeks."
"Vulcan Cyber offers a single pane of glass for centralizing our security data."
"Vulcan Cyber has helped reduce our organization’s mean time to remediation."
"It has allowed us to bring together multiple sources of information from different signal sources into a single point."
"The automation capabilities using the Vulcan API platform or the API feature allow me to easily automate scripts and reports and schedule them."
"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 gives the remediation team the focus points."
 

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 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."
"It would be a good idea if they have a simulation of attacks or a use case for finding a new vulnerability or dealing with a zero-day attack."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"The interface is a little bit clunky, and the reporting is not marvelous. There should be better integration of reporting between instances. Currently, the instance stands alone, and it produces a report. Being able to amalgamate those reports with another instance will be useful."
"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."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
"This is still a maturing product. Tenable is only a scanner for one ability, while other solutions like Rapid7 have more tools for verification. We still have to manually verify to see if the vulnerability is a false positive or not."
"We would like to have the option of using the solution for the cloud as well as on-premises with the same license at the same time. That would be very helpful."
"It would be extremely helpful to have a community group around the product."
"Their support is good, but there are some flaws as well. We often encounter some issues that are not applicable to Vulcan Cyber as a whole; they apply only to us because we have customized requirements. In such cases, when we reach out with specific data and issues to their support team, they sometimes come back and say that the issues have been resolved. However, when we test to see if they have been remediated, they are still there."
"Mainly, what I would like from them is more maintenance of the different connectors they have in the platform."
"We've faced situations where we required support on a Friday, and support wasn't available."
"It was a rough year in terms of setup. I had to set it up and onboard it. It was a significant effort from my side at least."
"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."
"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."
"An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports."
 

Pricing and Cost Advice

Information not available
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"The solution is expensive."
"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."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."
"It has a fair cost and very good cost-benefit ratio."
"The solution is worth the cost. It's a good investment."
"The is a free version of Tenable Nessus available."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
"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."
