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

"Technical support has been helpful and responsive."
"Real-time threat analysis is quick and takes action on threats immediately."
"They manage to solve detection quite nicely. There is some rather elaborate detection compared to other providers."
"The most valuable feature is Click-time URL protection."
"You don't have to buy a separate email security platform. You can enable that using their endpoint, and I like that. You don't have to have two agents running on the same box."
"It has certainly helped out our audit efforts because we each stay compliant in terms of various security standards."
"The Application Control code and the easy integration are valuable features."
"The technical support services are excellent."
"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."
"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."
"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."
"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 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."
 

Cons

"They could enhance the solution to work across all devices, including Android, iOS, and Mac, and make it more user-friendly."
"One area for improvement could be the pricing model."
"The security features need to be improved."
"It also needs network-based threat protection for shared folders and files."
"The support for new OSs and older OSs could be a little tighter. They need to be more upfront about what protection services they're going to provide on new OSs. I haven't seen the Windows 11 version out yet. It is either already released in Beta, or the Beta will be released soon. There could be a little bit more advanced updates on what they're doing to help protect Windows 11 environments. They can let us know in advance so that we know it is going to be protected. We can't roll out the new OS without putting end-point protection on it. So, they should tell us what is their support model for that, and what are they doing to protect Windows 11. They're not telling me, and that's a criticism. The same issue is applicable to all the other antivirus tools. It is not just Symantec; all of them have this problem."
"The cloud platform needs to have improvement in terms of the user interface and the different capabilities it has available. It needs to match the other leading next-gen EDR products that are available in the market. That's the reason why we are stepping away from Symantec. Their cloud environment is just generally lacking in comparison to others."
"Entire threat protection is not available for the advanced features."
"It should be able to collect information if the agent is disabled."
"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"Sometimes even their support doesn't know why we're seeing certain issues."
"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."
"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."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
 

Pricing and Cost Advice

"The pricing of this solution is inexpensive and affordable."
"Pricing is good. It is nice to have a great product at a fair price."
"Symantec Advanced Threat Protection's pricing is comparable."
"Symantec Endpoint Protection has an average price."
"The price is quite expensive."
