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.

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.

Chief Information Officer at a construction company with 1,001-5,000 employees
Has unified our IT teams by providing clear visibility into network vulnerabilities and accelerated remediation with real-world attack testing
One of the things that we've shared with Horizon is just the reporting. They've made a lot of changes over time, but when examining computers, most average normal people don't look at a computer and identify it as 114.82.117.180. They identify it as 'the printer for accounting.' When many of the reports give the very detailed technical IP address or serial number, that's really not helpful for anyone other than the person, the hands-on person that's trying to remediate it. All the managers, all the leaders, having information in that format isn't helpful. Being able to have information about what those devices are would be very helpful. There's a technical reason they can't just have an easy button because some people have really complicated networks. When examining things for the average company, the average executive, that 114 number, there's only one of those. But if examining an AT&T or a Walmart, it isn't unique. They haven't solved that problem. But for the 90% of companies, being able to have just a human readable name for all devices on your network in all of the reports all of the time would be the most beneficial.

Quotes from Members

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

Pros

"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 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."
"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."
"The integration of Tenable into our security ecosystem was very good."
"The price of Tenable.io Vulnerability Management is reasonable as it is ten times cheaper than other options."
"Tenable Vulnerability Management is the backbone of our vulnerability management and has affected my organization positively."
"It is pretty stable. I would rate it nine or maybe ten."
"There is no burden of updating or upgrading this solution."
"The initial setup is not complex."
"The initial setup is pretty straightforward."
"The stability is commendable, and I would rate Tenable ten out of ten."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."
"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"I rate the stability of the NodeZero Platform a ten out of ten."
"After the third party conducts the pen test, The NodeZero Platform is run, and it finds the same things they found and sometimes a few other things that they did not even identify."
"Penetration testing and scans are useful features."
 

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."
"I don't recommend Tenable.io Vulnerability Management for web scanning"
"I'm not satisfied with the reporting structure."
"The solution seems to focus too much on enterprises, and they really need a product that works for SMBs."
"The solution is a bit slow."
"Technical support from Tenable is rated six out of ten. It needs improvement in response time and addressing feature requests promptly."
"I'd like to see them improve their support."
"The pricing of the solution could be more reasonable."
"An area of improvement for this solution is being able to customize the dashboard. For example, the dashboard does not allow us to view a previous months vulnerability results alongside current results to make comparisons."
"The reports are quite useless."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
