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

"Honestly, it's one of the most transformational technologies we've implemented in our company."
"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"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."
"I rate the stability of the NodeZero Platform a ten out of ten."
"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."
"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."
"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."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"vRx seemed to be user-friendly and very easy to use."
"The system prioritizes vulnerabilities, identifying high, medium, and low risks, allowing us to focus on high-risk applications. It allows us to focus on high-risk applications and do the updates."
"I like that vRx is cloud-based. It protects the health of applications against zero-day threats."
"Agent-based scanning is the most valuable feature."
"Vicarius vRx's primary strength is its user-friendly interface."
"We can easily deploy patches for third-party applications. It automatically downloads the patches for you. You do not have to download them, upload them to the solution, and configure your own scripts or anything like that. It is all automatic."
"I liked the initial dashboard."
"Vicarius vRx has reduced our mean time to remediate vulnerabilities by 20%."
 

Cons

"You need to be cautious about what it scans, as it could potentially cause issues."
"The reports are quite useless."
"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."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"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."
"Sometimes even their support doesn't know why we're seeing certain issues."
"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."
"The multi-tenant portal has room for improvement."
"It would be beneficial if Vicarius vRx could implement smart tagging or suggest tags to create a group for these development tools, signifying that they should not be regularly updated."
"Unlike previous vulnerability management systems that relied on network scanning appliances to discover and assess endpoints, Vicarius' agent-based approach is less effective for devices like switches, routers, and printers where agent installation is impractical."
"In the past, Vicarius vRx was cheap, but now they have adjusted their pricing policy, resulting in higher renewal costs."
"We had an outage due to a change Vicarius performed in their system."
"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."
"I would like to see a way to build a virtual environment where we can test patches in real-time before we deploy."

"Vicarius vRx is reasonably priced."
"Vicarius vRx's per-asset pricing makes it easy for me to market to clients as it scales with their needs."
"From a pricing perspective, Vicarius was cheaper compared to other competitors."
"I am not sure how much it costs, but it would have saved us some costs."
"The price of vRx seems fair. None of our clients complained about the pricing. They all thought it was reasonable. Once people understood what it does, it didn't take much to get them to sign up."
