Enables us to prioritize and effectively address critical security issues
Evidence-based reporting helps us to prioritize and solve critical security issues. The new visualization feature demonstrates how an attacker can enter the system, highlighting the potential path that can be exploited and outlining all the steps the attacker could take. With that visibility, we can ensure the perimeter is strong and attackers cannot enter, thus reducing the risk. It has helped us prioritize issues. The visibility into how an attack could happen is valuable. For example, it highlights the system vulnerability and outlines where an attack could propagate. The visualization helps me to prioritize remediation, and if I don't know where to start, I can check to see the score that enables me to prioritize issues. I am using infrastructure-as-code scanning, and it's one of the useful features. In pre-production, it identifies embedded secrets and misconfigurations, including issues with Kubernetes or some privileged containers. This feature allows us to pass the audit and secure IaC code so that it isn't easily exploitable by attackers. We can more proactively work to identify and resolve vulnerabilities by using the dashboard and the alerting system that SentinelOne provides. It helps us with audits and compliance. We can show the compliance in percentage. We can confidently say that our company or infrastructure is very secure. It has improved our security posture by 30% to 35%. It has reduced our false positives by 30%. It has helped teams collaborate better. The security team manages SentinelOne Singularity Cloud Security, and when it flags vulnerabilities, they are forwarded to DevOps for remediation. Previously, we needed to identify and report the issues, but there would be lapses in communication. Now, there is a centralized dashboard that anyone can look at and see the open issues and work on them.

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.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments
Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.
