Works at a healthcare company with 10,001+ employees
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.

Pros

"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."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"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."
"Zafran is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"With the pipeline of detection and DefectDojo, we are able to see the real vulnerabilities, and we fix them."
"Tenable SC is good for reporting and alerting. The filtering feature is also very valuable. Its integration with multiple vendors is quite good. It can be integrated with SIEM solutions and PAM solutions such as Thycotic, which is very helpful."
"We use Tenable to scan all of our environments and plugins for vulnerabilities. Tenable helps us discover network vulnerabilities to threats and piracy."
"Compliance and vulnerability scans are most valuable. Compliance scan helps in validating how our teams are complying, and vulnerability scan helps in future-proofing. Its vulnerability detection is accurate."
"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."
"Tenable.sc is user-friendly."
"The most valuable feature of this solution is the vulnerability assessment."
"Tenable is the leading product for vulnerability scanning."
"Very customizable with a lot of templates."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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."
"We need something to notify the team responsible for a product when vulnerabilities are found."
"It could be more user-friendly for creating custom reports."
"Tenable's technical support has declined in quality over time. While they used to be excellent, achieving ratings of eight or nine, they now rate around six or seven due to longer response times and less thorough assistance."
"Tenable SC can improve by making it easier to create complicated reports and have more effectiveness in the remediation area for comparison between the scans."
"The reports and plugins for reports and scans could benefit from enhancements."
"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."
"It's good at creating information, it's good creating dashboards, it's good at creating reports, but if you want to take that reporting metadata and put it into another tool, that is a little bit lacking."
"In terms of configuration, there is some level of flexibility that we are not able to achieve."
"The solution is expensive."
