Data lineage and quality checks have streamlined team-wide collaboration and business context
The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely. There are features I wish Microsoft Purview Communication Compliance had that it does not provide today. Enterprise-level lineage is one such feature. As of now, if Microsoft were to provide this tool for free when you buy Microsoft Fabric, I feel that would be better. This would also result in lower license costs. I do not have any changes I would make to Microsoft Purview Communication Compliance at this time.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.
