Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers

Windows Security Patching Operation III (Cyber Operations) at CBTS

Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.

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.
