The vast majority of times they are able to resolve the exact questions my team has on the first attempt, which is really good for customer or technical support.

One of the areas where improvement is needed is in the visibility and reporting for large enterprises.

IDM Consultant at GCA Consultoria de Informática Ltda
Identity management has streamlined user lifecycle and now guarantees first-day access
The best features Armis offers include the interaction with my manager in Brazil, whose first name is Rui, and who provided a lot of experience, especially Horácio, who used to work for Microsoft. Horácio helped with issues related to Active Directory and provided ideas on how to best integrate the solutions. The aspect of Armis solution that stood out to me was its flexibility to integrate different applications. The collaboration of the team is really important and key for the project to go well and bring the results the customer is looking for. The solution has the necessary resources and connectors that have built many of the rules needed for integration, regardless of whether the application is an Active Directory, an LDAP directory, a database, or even a specific solution such as SAP. It is also flexible enough to build the business rules that apply specifically to that customer. Armis has positively impacted my organization and my client's organization by ensuring that on day one, new users had all the access they needed to work for the applications that were integrated. Additionally, if a user was dismissed from the company, they would lose all access to the integrated applications because Active Directory, which was key for user authentication, would disable their account. I do not recall any specific statistics regarding measurable results, but there was positive feedback from managers concerning the process during the time I was there.
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.
