Featured Reviews

Gabriel Woolverton - PeerSpot reviewer
Penetration Tester at a tech consulting company with 1-10 employees
Open source and easy to set up
Offensive Security Penetration Testing Services has a rating system for how exploitable vulnerability is, but that rating system does not really give you any transparency into how the rating for that exploit was reached. It would be useful to see on the back end what data led them to specify that a specific exploit may not be very good or may be great. If we had some data correlated with that, we could see why it is that this one should be successful versus another.
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

"Compared to Rapid7, Offensive Security might have more support on the back end in relation to exploits for Metasploit, for example."
"Offensive Security Penetration Testing Services is open source, so it is free and there are no licensing costs."
"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."
"The NodeZero Platform by Horizon3.ai has positively impacted our organization by definitely increasing our security posture significantly."
"I rate the stability of the NodeZero Platform a ten out of ten."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"The NodeZero Platform by Horizon3.ai is better than manual penetration test scans, definitely worth trying if you are considering using it because it reduces the time and cost associated with manual scans and presents the data in a very clear way that even non-technical people can understand."
"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."
"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."
"Using The NodeZero Platform by Horizon3.ai has helped us close more deals and speed up our sales cycle, as it is well-known that we sell to customers within the Horizon company through the partner portal and deal registration."
 

Cons

"Offensive Security Penetration Testing Services has a rating system for how exploitable vulnerability is, but that rating system does not really give you any transparency into how the rating for that exploit was reached. It would be useful to see on the back end what data led them to specify that a specific exploit may not be very good or may be great."
"The NodeZero Platform by Horizon3.ai could greatly improve their feature request and product suggestions process."
"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."
"I feel there could be improvements in scalability, although at this point I have no specific negative points to report."
"The NodeZero Platform by Horizon3.ai can be improved in some ways, particularly regarding the test scan sometimes."
"The reports are quite useless."
"The setting up of new runners in The NodeZero Platform by Horizon3.ai could be simplified a little bit; currently, it's kind of a three-step process where you have to set up the assets in a separate menu, then a separate menu to set up a template, and then you actually set up the runner, so it would be nice if from the runner creation screen it just took you through the whole process instead of having to navigate to three different tabs."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
