Creates value with advanced investigation capabilities while seeking improved integration with varied platforms
My primary improvement request would be for auxiliary logs, as they represent our biggest need. While we have automated deployments now, Microsoft Sentinel is fairly easy to deploy, although we face challenges with integrations related to AWS and GCP, particularly with Google. The integration challenges arise from both sides; Google tends to be noisy, and we find only ten analytic rules out of the box, necessitating the use of Defender for Cloud for alerts, which indicates a need for better documentation during deployment. The story between UEBA and Defender for Identity and Intra needs to be further explored and defined. There's some confusion on what is happening from a user and entity behavior.
