Featured Reviews

Peter Nowak - PeerSpot reviewer
Business Development Manager for Cybereason at Bechtle
Quick response and reliable restoration enhance security operations
If the language barrier was addressed, it would lower the barrier for a number of German customers. It would take away a unique selling point for our own specialist managed service. I'm a bit hesitant, however, this would improve the product or the offering. Detection time already is very quick. The completeness of the offering was integrating more data. I am discussing with a customer who wishes to include identity data. Detecting early when someone tries to compromise your ID would be a nice feature.

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.
