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.

Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.

Windows Security Patching Operation III (Cyber Operations) at CBTS
Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.
