Featured Reviews

Gabriel Woolverton - PeerSpot reviewer
Penetration Tester at a tech consulting company with 1-10 employees
Wide range of coverage and free
A useful improvement would be to have white papers for specific vulnerabilities readily available. It seems like they are not always linked when you are looking for a vulnerability identifier in the database. It would be useful to ensure that that information is readily available. That way, if you need to dive deeper into a vulnerability, you would have the capability to do so basically right there on the website.
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.

Quotes from Members

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

Pros

"The initial setup is very straightforward. This is not a tool that you have to set up yourself. All you have to do is just access their web-based vulnerability database application, which is open source and available to pretty much anyone."
"Rapid7's wide range of coverage, in terms of vulnerabilities and exploits linked to vulnerabilities, is its most valuable feature."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Otherwise, the solution itself is very fine and I would recommend it as an MSP partner or as a user of the tool to pretty much any company."
"What I appreciate the most about The NodeZero Platform by Horizon3.ai is its distinctive competitive advantage, which is the ability to bundle multiple security solutions into one single tool."
"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."
"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."
"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."
"If someone was looking into this product, I would absolutely recommend it."
"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."
 

Cons

"A useful improvement would be to have white papers for specific vulnerabilities readily available. It seems like they are not always linked when you are looking for a vulnerability identifier in the database."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"The NodeZero Platform by Horizon3.ai could be improved by reducing the elapsed time from identifying a zero-day vulnerability from their QA environment to their production environment."
"I would like to see an improvement in the notification management."
"The downsides of The NodeZero Platform by Horizon3.ai are that it is an expensive tool; it is a very expensive tool."
"The reports are quite useless."
"I think customizability is one area of The NodeZero Platform by Horizon3.ai that could be improved or enhanced."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"I feel there could be improvements in scalability, although at this point I have no specific negative points to report."
