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.

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.

Works at a manufacturing company with 51-200 employees
Has a lot of backend issues and doesn't work the way we thought it would
We did some automation. We kicked off scheduled updates to update our systems, but it did not work. When we attempted to scale the product and update multiple systems, we ran into a lot of issues. We also ran into the issue of it creating double assets. I am not sure how that happened, but it was a mess and still is a mess. That is where we are. They should probably go back to the drawing board and make sure that they can patch Linux. In our environment, we are 99% Linux. They may need to build their own lab and have a lot of Linux devices. They can have old different Linux systems and 50 or 60 of them and attempt to do an update in their own lab and see what happens. I am still not sure if that would give them a true test because we have systems here with Docker containerization and all kinds of things on it. They will have to mimic what some of these environments will look like. I am pretty sure that the tool works great when it comes to Windows, but when you are in an environment that has different flavors of Linux at different version levels, that may pose an issue.

Quotes from Members

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

Pros

"We are able to see the real risk of a vulnerability on our environment with our security tools."
"We saw benefits from Zafran Security almost immediately after deploying it."
"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."
"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."
"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."
"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."
"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."
"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."
"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."
"I rate the stability of the NodeZero Platform a ten out of ten."
"Vicarius vRx's primary strength is its user-friendly interface."
"I like that vRx is cloud-based. It protects the health of applications against zero-day threats."
"I also like how easy it is to use. We instructed some companies on how to use it, provided them with an account, and gave them the ability to deploy and patch. They could quickly figure it out. We can spend an hour in the office showing someone how everything works, and they're good to go. It's the same with our customers."
"Since we started using Vicarius vRx, I have not had to worry about patching the software."
"Agent-based scanning is the most valuable feature."
"I liked the initial dashboard."
"Vicarius vRx has reduced 70% of the time we spend on patching."
"The other products we looked at had patching tagged on another product, whereas this solely looked after the patching and vulnerabilities, which is good. We did not see any other products with such capability."
 

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."
"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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"Sometimes even their support doesn't know why we're seeing certain issues."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The reports are quite useless."
"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 speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"It would be good if there were more login options. At the moment, it sends you an email to verify your email address, and then you can log in. It would be beneficial to have other options for signing in, like MFA or maybe security keys, especially since it is a security product."
"We had an outage due to a change Vicarius performed in their system."
"I would appreciate additional filter options, such as the ability to filter by AWS tags."
"We did some automation. We kicked off scheduled updates to update our systems, but it did not work. When we attempted to scale the product and update multiple systems, we ran into a lot of issues. We also ran into the issue of it creating double assets."
"I would like to see a way to build a virtual environment where we can test patches in real-time before we deploy."
"While I appreciate the automation of vulnerability management, Vicarius vRx's current manual patchless application is a point for improvement."
"Another complaint we've gotten is that the portal doesn't remember your username and password. You tell them your email, and it sends an invitation. You need to click that, and it takes you to a new portal, where you can finally log in. Maybe it's a security precaution, but it seems like a lot of extra steps to log in."
"I don't like logging in. The portal could be a better process. You could use some third-party push notification rather than sending an email, waiting for the link to generate, and clicking on it. That would be good. It's somewhat frustrating when I need to log in."
