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

"Rapid7's wide range of coverage, in terms of vulnerabilities and exploits linked to vulnerabilities, is its most valuable feature."
"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."
"The return on investment from The NodeZero Platform by Horizon3.ai is almost one hundred percent."
"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 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."
"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."
"Penetration testing and scans are useful features."
"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."
"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."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
 

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."
"The downsides of The NodeZero Platform by Horizon3.ai are that it is an expensive tool; it is a very expensive tool."
"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."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"When it comes to the stability of The NodeZero Platform by Horizon3.ai, I would rate it around seven to eight because the stability is not that high initially due to the need for daily updates and modifications as new vulnerabilities appear."
"The reports are quite useless."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"Sometimes even their support doesn't know why we're seeing certain issues."
