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."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"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."
"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."
"The return on investment from The NodeZero Platform by Horizon3.ai is almost one hundred percent."
"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."
"Right now, using it for networks is great, and you could really do a lot with their continuous testing, which I thought was a great feature."
"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."
 

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 reports are quite useless."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"Running these tests does take quite a while to complete for the first time since we are conducting every single test, and it actually took several weeks."
"The NodeZero Platform by Horizon3.ai could be improved by speeding up the time from initializing a test to actually starting the test, as the deployment of the underlying infrastructure can take several minutes, sometimes over 10 minutes."
"If we have had problems, that is with the actual licensing style they are using."
"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."
"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."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
