Featured Reviews

MuhammadNadeem - PeerSpot reviewer
Sr. Network Engineer at a tech services company with 1-10 employees
Has supported urgent deployments and enabled inline threat protection but pricing and features could be more flexible
I am not using Palo Alto Networks VM-Series mostly, but based on my experience, there are some deficiencies in Palo Alto Networks VM-Series. Having those features missing, we are not proposing Palo Alto Networks VM-Series to all customers. However, for urgency and for some solutions that customers need for some of their other sites and subdivisions, we are providing the same.
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.
