Merit Network Cuts Alerts by 25% and Gains Edge Visibility Across Its Michigan Network
Summary: Merit Network, the nonprofit research and education network founded in 1966 that runs more than 4,000 miles of fiber across Michigan, integrated GreyNoise Block's continuously updated IP lists into its detection and alerting pipeline and cut alert volume by up to 25%. At its scale that meant roughly 500 million fewer events per month, dropping from about 1.9 billion to about 1.4 billion, and freed about 8 hours a week across its security team.
Bottom line: Merit absorbed the reduction on top of filtering and blocking it already had in place, which suggests the remaining 1.4 billion monthly events are the ones its analysts still have to work through. The team also deployed more than 250 deception sensors configured to match its members' equipment profiles, so the scanning it now observes is aimed at the systems it actually protects.
