Shaun Hunt

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

"It has the added advantage of offering forensic analysis."

"We have been able to monitor access to files from each of our workstations."

"Some of the features that are highly appreciated are its robust data loss prevention capabilities, flexible deployment options, and the ability to monitor data transfer across multiple vectors."

"The most valuable feature of Digital Guardian is its reputation. They have scored high on the Gartner Magic Quadrant."

"I like the solution's adaptive inspection and container inspection."

"It has been scalable."

"The feature we call desktop recording is the most valuable aspect of the solution. Not only can we collect data from the user's usage, but we also capture his screenshots when he is trying to steal the data."

"There is a built-in endpoint detection response that helps save money."

More Digital Guardian pros

"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."

"Penetration testing and scans are useful features."

"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."

"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."

"Overall, I'd rate NodeZero at nine to 9.5 out of ten."

"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."

"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."

Cons

"It would be helpful if there was an on-premise version of the solution for companies that cannot use the cloud, such as government sectors."

"Technical support could be better."

"I would like to see the workflow, to get all the rules and policies set up, be less complicated."

"Some features on Mac and Linux are not complete currently. For example, some device control features haven't been transferred over to the other systems. If they could have their Windows features also available on Mac and Linux, that would be perfect. Some of our customers have a Mac environment for their RD environment. Having the solution fully capable of handling everything in a Mac environment is crucial."

"There are a lot of issues with the current version of the Endpoint agent. It's not stable, it's resource-consuming, and there are some performance issues. If they could improve the stability of the agent it would be great."

"If the client uses Windows 10 or 11 and Microsoft updates the operating system's version, Digital Guardian must update their product to match compatibility."

"The room for improvement with Digital Guardian is that it will be better with the Linux agent because it is the only DLP solution for Linux workstations. It still needs to upgrade the agents to the latest version for the Linux kernel."

"Digital Guardian is an excellent solution but our experience with the partner has been the most horrible experience we have ever had with any partner."

More Digital Guardian cons

"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."

"Sometimes even their support doesn't know why we're seeing certain issues."

"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."

"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."

"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 only issue we’ve encountered is that sometimes the scans take a long time to complete."

"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."

More The NodeZero Platform by Horizon3.ai cons

Pricing and Cost Advice

"Digital Guardian has both, subscription and perpetual licenses, but I think when everything (all technologies) will go to the cloud they will only offer subscriptions."

"The price of Digital Guardian is on the higher end compared to other vendors."

"I rate the solution's pricing an eight out of ten because Digital Guardian is expensive."

"If I compare Digital Guardian with Symantec, the license cost is lower, but McAfee can be cheaper than Digital Guardian. It depends on how many licenses you plan to buy and how big the project is. The cost is not so high as Symantec, but not as cheap as McAfee. They can easily sell the solution for price."

"The cost was around $300,000."

"The price of Digital Guardian is expensive."
