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.

Centralized analytics have strengthened patch visibility and support efficient regulatory reporting

From my experience, I assess the product's analytics capabilities as successful. It helped us significantly with patching and managing the risk of the patching process across all our environments, including network devices with Windows and Unix systems. The product covered several environments and gave us exactly what we needed in our environment. Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments. It covered the patching process, and we previously faced many issues regarding how to patch different environments, how to monitor the patching process, and whether it was successful or not. We obtained good reports showing when patches were closed and the details of each patch, including who executed it and everything related to the patching process until it was closed. This gave us good details about the process which helped us significantly in our reporting and even in audits, whether internal or external. We learned how to close audit issues safely and successfully. We used the dashboards for real-time threat insights and extracted several dashboards from Tenable Security Center. We use these dashboards in our cybersecurity dashboard and committees that we have. These dashboards are part of our committees, especially the cybersecurity committee and other committees that we attend.
