SH
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.

Supervisor, Client Security at a consultancy with 11-50 employees
World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.

Quotes from Members

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

Pros

"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."
"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's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"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."
"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."
"Penetration testing and scans are useful features."
"Being able to protect and trust nothing by default, known as zero trust, is the most important feature to me."
"I really enjoy ringfencing and elevation features. It makes my life easier because I do not have to get on a computer to elevate a prompt to allow users to run something they run every day as an admin."
"The pre-built policies and the fact that I get notified when a user requests an application are significant."
"The single pane of glass management for all this functionality is really the best feature, as it unifies many utilities that would have been separate costs before and lets us sleep at night knowing that things are being monitored 24 hours."
"ThreatLocker provides visibility into user activity and application usage, empowering organizations to define acceptable applications and web browsers."
"It's easy to use in regards to reducing attack surfaces."
"The great thing is that if you get a malicious email and you try to run something, ThreatLocker is not going to let it do anything. It is not going to let anything infect your network."
"Being able to protect and trust nothing by default, known as zero trust, is the most important feature to me."
 

Cons

"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"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 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 reports are quite useless."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The portal can be a little overwhelming at times from an administration point of view. It displays a lot of information, and it's all useful. However, sometimes there is too much on the screen to sift through, especially if you're trying to diagnose a client's problem with a piece of software. Maybe something has stopped working since they updated it, and we need to see if ThreatLocker is blocking a component of that software."
"If you have a thousand computers with ThreatLocker agents on them, when you approve or create a new policy saying that Adobe Reader that matches this hashtag and meets certain criteria is allowed to be installed, it applies at the top level or the organization level. It applies to every computer in the company. When you make that new policy and push it out and it goes out and updates all of the clients. Unfortunately, at this time, it does not look like they stagger the push-out."
"One of the things I would really like is the ability to create custom groups and assign machines to them."
"Initially, the learning curve was slightly high for me, however, that has been resolved now."
"A valuable addition to ThreatLocker would be a column in the audit page displaying a VirusTotal score for each file."
"When I first came on board, it was trickier to learn."
"It's very annoying to uninstall. You have to go into the online control panel and disable tampering for a device before it'll let you uninstall it without complaining really loudly."
"Better visualizations of what exactly is happening in our logs would be helpful. There can be more visuals on what has been elevated. Presenting this in a more refined manner would be beneficial."
 

Pricing and Cost Advice

Information not available
"Others say ThreatLocker is too expensive, and I tell them they're dreaming. It's well-priced for what it does."
"The price of ThreatLocker Allowlisting is reasonable in the market, but it is not fantastic."
"Its price is fair. They have added some additional things to it beyond allowlisting. They are up-charging for them, but in terms of the value we get and the way it impacts us, we get a bang for our buck with ThreatLocker than a lot of our other security tools."
"I find ThreatLocker's pricing to be reasonable for the services it provides."
"Considering what this product does, ThreatLocker is very well-priced, if not too nicely priced for the customer."
"The pricing works fine for me. It's very reasonably priced."
"I believe ThreatLocker's pricing model is fair and flexible, allowing account managers to offer customized deals based on our specific needs."
"The pricing is pretty fair, considering other solutions. Licensing-wise, it did not take long."
