Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.

Quotes from Members

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

Pros

"This is a good solution, and whatever our requirement is, all of the features are there."
"Endpoint to network protects the line."
"It has certainly helped out our audit efforts because we each stay compliant in terms of various security standards."
"The stability is excellent."
"Currently we have 800-plus nodes connected with this solution, without any issues. The solution is scalable."
"They manage to solve detection quite nicely, with rather elaborate detection compared to other providers, and Symantec also provides a useful set of information linked to each of the attacked computers."
"Endpoint to network is a good feature, it can protect the line."
"The Application Control code and the easy integration are valuable features."
"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."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"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."
"The best feature of The NodeZero Platform by Horizon3.ai is that it is an autonomous pen testing tool that knows how to penetrate into the system automatically and perform lateral movement inside the network without the need for scripting."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by catching vulnerabilities and exploits that we wouldn't otherwise be able to find as easily or as quickly, so I'd say it helps better our cybersecurity posture."
"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 by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization."
"We chose The NodeZero Platform by Horizon3.ai because, first, of its superior technical capability for the use cases we were looking for, second, the cost, which we believe was much more affordable than the other products, and third, the customer and technical support was very good for us."
 

Cons

"The support team that Symantec offers didn't know how to solve issues even though they referred to themselves as "engineers"."
"It should be able to collect information if the agent is disabled."
"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."
"Solutions like CrowdStrike, ESET, and SentinelOne have really jumped ahead on behavioral and algorithm-based detection capabilities. Symantec is trying to catch up, but they still have some limitations of being an old-school AV protection program and adding AI and behavioral learning and detection algorithm."
"I think SonicWall and McAfee are better solutions."
"An improvement could be made on the reporting because then it would be easier to collect information and submit it for compliance."
"Scalability could be better."
"The product's support services need improvement."
"However, my team struggles with the onboarding side of our engagement, which should have been more robust; having a statement of work and a clear definition of success would have been beneficial."
"If we have had problems, that is with the actual licensing style they are using."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"The downsides of The NodeZero Platform by Horizon3.ai are that it is an expensive tool; it is a very expensive tool."
"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."
