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.

Flexible and reduces IT operations but requires local data sovereignty and competitive pricing
I prefer having local data sovereignty. It would be advantageous for Palo Alto to have local data centers across different countries to adhere to this requirement. I also have a concern regarding pricing, which is perceived as high compared to competitors. Improvements should focus on response times and reducing the time taken to reach solutions.
