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

"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."
"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 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."
"It is a very good and user-friendly product."
"The solution has a lean and easy-to-use interface that is not confusing to first-time users."
"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."
"The most valuable feature of the product is the Assurance Report Card, which gives us an overview of the security poster in just a simple glance."
"My advice for those considering Tenable Security Center is to note the benefit of upgrading vulnerable devices."
"This solution has a much lower rate of false positives compared to competing products."
"I found the dashboard features very useful. It made it easy to track remediation progress. I could publish dashboards to remediation teams and track the progress on the dashboards."
"The most valuable features in Tenable SC are scanning and analysis."
 

Cons

"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."
"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."
"We need something to notify the team responsible for a product when vulnerabilities are found."
"The vulnerability scan does not work correctly until the access privileges are set by the system administrator."
"A good plugin editor would be a good additional option for the Security Center."
"The web application scanning area can be improved."
"Tenable.sc's user interface could be improved."
"We would like to see the inclusion of external IPs and simplified reporting that's easier to deal with"
"The reporting needs a lot of work on the template."
"Deploying Tenable.sc is highly complex because it's an on-prem solution, whereas Tenable.io is cloud-based, so you can go live as soon as you log in. Tenable.sc involves significant integration with other on-prem solutions, and the deployment takes about two to three weeks with the help of a system integrator"
"The product could be user-friendly, and they could enhance the web application's security features."
