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.

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