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.

Ensuring long-term reliability while seeking internal email management enhancements
Prisma is a commercial name of the firewall now, but we don't work with the cloud product. Only our company is using it and we do not recommend it to customers. For us, it's transparent because it's a cloud product, so we don't really know the version as it's always updated. We have not had any problem, but it's difficult to report on what's going on because some days they can wash out perhaps 100 mails, and then it's difficult to say how many attacks you have reached. The right email has been washed out and then nobody has complained. We do not use the Threat Visualization feature; as we are in MX, the mail is washed out before it is in the mail inbox of the user, thus avoiding any problem requiring a reservation. In fact, there is no integration with existing security frameworks. The only problem we can have is that as we have no API interface, there is no inspection of internal mail. I rate Trellix Advanced Threat Defense a nine out of ten.

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."
"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."
"Penetration testing and scans are useful features."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"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."
"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 most valuable features are the administration console and its detection and response module."
"It is very scalable."
"Its greatest strength is the DXL client which can rapidly disseminate attack information to all clients via the McAfee Agent instead of going through the ePO server."
"I recommend this solution because of its ease of use."
"It is stable and reliable."
"The fact that in 10 years, we have had no problem is the most valuable feature for us; it's really a washing machine, but the only problem we face is that it's difficult to report on this product."
"It stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"Provides good exfiltration, and is an all-in-one product."
 

Cons

"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."
"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."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"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."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"Make the ATD system a part of the whole product and take the whole thing onto the cloud. While it is there already, it is not to the same level as the on-premise version."
"The only problem we can have is that as we have no API interface, there is no inspection of internal mail."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
"We'd like them to be better at dealing with script threats."
"I would like to see future versions of the solution incorporate artificial intelligence technology."
"There could be a tool that automatically updates all-new Microsoft IPs, which are available for free to connect to the client."
"This solution needs to be made "cloud ready"."
"Lacks remote capabilities not dependent on the internet."
