Featured Reviews

Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
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.

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

"I believe that The NodeZero Platform by Horizon3.ai has kept me safer in a cybersecurity sense."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by allowing my security team to be more efficient and focus on the most valuable work at the highest criticality."
"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."
"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 by Horizon3.ai has positively impacted our organization by definitely increasing our security posture significantly."
"The NodeZero Platform by Horizon3.ai has allowed us to quickly and easily identify the exploits in our environment that are greatly increasing our risk, simplified that process and also our remediation process, allowing us to more easily work with teams to show how it is exploitable and what they need to do to fix those issues, significantly improving our finding discovery and remediation process of vulnerabilities and overall decreasing our risk."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"The automated updating of scans has been a huge value-add for us; we're a small cybersecurity team, so speed to value is the biggest thing to multiply the force of our small team, saving a lot of man-hours."
"The product is expensive, but it is better than the rest of them in the industry."
"I see ROI, as it stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"This solution is very easy to use and requires little to no training."
"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."
"Provides good exfiltration, and is an all-in-one product."
"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."
"The features I find most valuable are: the management, the ability for automatic remediation of threats and it can successfully detect a threat, and to act upon it."
"If a system admin can put in the patience to read and constantly update the ePO system in terms of rules, enforcing them at regular intervals, you can safely go to sleep every night."
 

Cons

"If we have had problems, that is with the actual licensing style they are using."
"The reports are quite useless."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"I would like to see an improvement in the notification management."
"The speed of the scans takes some time, but in my opinion, it is not surprising for what it is doing."
"I think customizability is one area of The NodeZero Platform by Horizon3.ai that could be improved or enhanced."
"I haven't really come across anything that I say needs to be improved with it, other than the container runner, which tends to lose time."
"Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes."
"I would like to see future versions of the solution incorporate artificial intelligence technology."
"The only problem we can have is that as we have no API interface, there is no inspection of internal mail."
"Some of our customers have mentioned the lack of a tool that would allow for remote capabilities without being attached to the internet."
"This solution needs to be made "cloud ready"."
"This product does the job, but it is not flexible enough to do new environments yet."
"Lacks remote capabilities not dependent on the internet."
"We'd like them to be better at dealing with script threats."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
