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The user interface of Tenable Nessus feels outdated and could be more user-friendly.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

"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 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."
"Zafran is an excellent tool."
"The most valuable feature of Tenable Nessus is vulnerability assessments. There are a lot of threats around the world and this solution is the first to come out with detection rules."
"Once you get past the initial implementation, the solution is very stable."
"Tenable Nessus is one of the best vulnerability assessment tools, that I know."
"The most valuable aspect of this solution is that you receive the entire report, which details the breakdown, especially in terms of critical, high, low, and mediums."
"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."
"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."
"Tenable Nessus is cheap and flexible."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"Vulcan Cyber gives the remediation team the focus points."
"They recently upgraded their UI, which is great. It is user-friendly."
"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."
"The interface of Vulcan Cyber is intuitive with a lot of information about vulnerabilities, which helps in classifying and analyzing threats."
"The most notable aspects include having prioritization capabilities and custom scripts."
"It has allowed us to bring together multiple sources of information from different signal sources into a single point."
"Vulcan Cyber has helped reduce our organization’s mean time to remediation."
"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."
 

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."
"Tenable Nessus is not feasible for a large company."
"The product must be more comprehensive."
"Multiple steps to create an actionable plan will be a great addition to Nessus."
"There could be an integration between Tenable Nessus and other Tenable products. It will help us manage all the solutions using one dashboard."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"Consumes more system resources when it's running."
"The tool needs to upgrade asset tracking."
"An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports."
"Monitoring of the evolution of campaigns and perhaps having more customized options for monitoring them would be great."
"Improvements are needed in providing more concise details on how to apply remedies for particular vulnerabilities. I would like to have more information about the remedies for particular vulnerabilities so that we do not have to go through the CVE numbers and relevant pages to check for a particular vulnerability and its remedy."
"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."
"We've faced situations where we required support on a Friday, and support wasn't available."
"We wish we had more insights into how they weigh the risks associated with the threat intel."
"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."
"It would be extremely helpful to have a community group around the product."
