Has become an indispensable tool in our cybersecurity arsenal
While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

Easy to use with efficient vulnerability reporting and team collaboration
Use case, so all the reports from GitLeaks, DefectDojo, GitLeaks or dependency check or Trivy, they make reports, and we send this report to DefectDojo to have CVMs, Central Vulnerability Management. DefectDojo is Central Vulnerability Management. If you have a dashboard to set, we have…

Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"With the pipeline of detection and DefectDojo, we are able to see the real vulnerabilities, and we fix them."
"Tenable Security Center scans networks and gives reports."
"It's a very useful tool."
"The most valuable feature is the automatic and periodic management of security scans, along with the ability to consolidate all information into a single dashboard."
"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."
"The most valuable feature of this solution is the vulnerability assessment."
"The solution is very intuitive and the dashboards are simple to use."
"The most effective feature of Tenable Security Center for detecting vulnerabilities is its capability for critical mapping."
"It basically reviews our threat landscape vulnerability."
 

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."
"We need something to notify the team responsible for a product when vulnerabilities are found."
"The solution should provide better web application features and support."
"Additional costs are associated with using the solution, as additional scanners are required for different endpoints connected to the Tenable Security Center. If Tenable Security Center could extract information from these scanners automatically rather than manually, it would enhance user-friendliness for customers."
"The GUI could be improved to have all concerns and priorities use the same GUI, allowing them to see all tickets, assign vulnerabilities, and assign variation failures to each member of their team."
"There's a lot of information being streamed out of the reports. What would be nice, and maybe we just haven't found it, would be more of an executive-type view. We still expect it to collect all this information, but we would like a feature that would allow us to show it to an executive or a director or someone like that and give them some type of high-level overview but not get into the nitty-gritty."
"Tenable's reporting engine needs improvement. It needs to be more efficient and add more features."
"In terms of configuration, there is some level of flexibility that we are not able to achieve."
"Security can always be improved."
"Tenable SC could be improved with additional connectivity to external company postures and the capability of managing and sustaining agents in the systems directly without additional platforms in the middle."
