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.

Advanced detections have exposed credential abuse early and stop lateral movement across environments
I found this interview absolutely fantastic. I would advise others looking into using SecureWorks Taegis VDR that it is one of the reliable solutions anyone should try, and if it yields good results, I would definitely recommend switching to SecureWorks. I recommend SecureWorks Taegis VDR because it is highly scalable by design and well-suited for mid-sized to very large enterprises, including global hybrid and cloud-heavy environments. Its cloud-native elastic architecture is built as a cloud-native SaaS platform that automatically scales compute and storage as telemetry volume increases without requiring customer-side infrastructure scaling, and it can handle bursty workloads such as incident spikes and ransomware attacks. I gave this product a rating of eight out of ten.

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Quotes from Members

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

Pros

"Zafran is an excellent tool."
"We saw benefits from Zafran Security almost immediately after deploying it."
"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."
"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."
"I chose SecureWorks Taegis VDR because I trust SecureWorks, having worked with McAfee, Symantec, Trend Micro, Kaspersky, Carbon Black, Cylance, CrowdStrike, Palo Alto Cortex XDR, and more, and I would say SecureWorks Taegis VDR is outstanding among all the other vendors in terms of functionality, ease of access, and UI friendliness."
"It is a one-stop solution for different needs with separate APIs. The product offers different solutions for different companies."
"I like its ease of use. It has the script that is pre-built in it, and you just got to know which ones you're looking for."
"The solution is easy to understand for users because instructions are included on the platform."
"The most valuable features are that it's fast, it's easy to use and it provides good reports."
"Out of the box, the product works well for us, so it's not a tool that we need to customize very much."
"The automatic scanner and scheduler are pretty cool."
"Nessus' most valuable feature is vulnerability management because it helps to discover vulnerabilities proactively and integrates with patch management solutions so you can push patches."
"Nessus is good at finding out what nodes you have in place. It will then provide you a report, by node, of what the vulnerabilities are. It does it quickly and stealthfully."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
 

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."
"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."
"I would like to improve SecureWorks Taegis VDR by enhancing the dashboard to provide a holistic view with granular data."
"One area with room for improvement is instead of there just being a PDF format for output, I'd like the option of an Excel spreadsheet, whereby I could better track remediation efforts and provide reporting off of that."
"The price could be reduced."
"Model OS costs (and its segregation schema for individual modules)."
"In Nessus Professional, the main drawback was that we could have a single-user login password. So it could be better in terms of security."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"Tenable Nessus could improve reporting and information sharing. It would be helpful if we could share the reports and have a little bit better flexibility in the reporting of the data."
