Head Of IT at Cirrus Response
Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight
When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

Automated testing has transformed how we deliver fast, consistent security assessments
The key capabilities of the NodeZero platform by Horizon3.ai that I have found most valuable are its speed, scalability, and consistency. It is able to cover a broad scope in a relatively short period of time, which delivers significant efficiency gains when compared with traditional manual testing. It also provides a more consistent outcome, as the process is not influenced by human bias or variability. One of the most valuable features is the ability for security teams to remediate and retest vulnerabilities immediately. The one-click verification capability is particularly effective, as it allows fixes to be validated quickly without the need to rerun the entire assessment. This streamlines the remediation cycle and supports faster confirmation of security improvements. The platform’s real attack capabilities have also helped reduce false positives in the identification of vulnerabilities across our on-premises systems. Because the findings are evidence-based and validated prior to reporting, the results are more reliable and actionable. This enables us to focus our efforts on confirmed security issues that genuinely require attention, rather than spending time investigating theoretical or unverified exposures. The NodeZero platform also strengthens my understanding of potential security threats through its continuously updated capabilities. With new vulnerabilities emerging and being exploited in the wild on a regular basis, it is valuable to have a platform backed by a strong research and development function that continuously updates attack content to reflect the current threat landscape. This makes the platform effective not only as a point-in-time validation tool, but as part of an ongoing and continuous security assurance programme.
