What is GreyNoise?
Founded in 2017 by Andrew Morris, GreyNoise Intelligence operates at the intersection of big data and cybersecurity. The firm specializes in the design of sophisticated security software that identifies, classifies, and analyzes internet-wide scan and attack traffic. Unlike traditional threat intelligence platforms that focus on known malicious indicators, GreyNoise provides a unique perspective by cataloging the behavior of benign and malicious actors across the global internet. This capability allows security analysts to drastically reduce false positives, thereby optimizing incident response workflows and enhancing overall organizational security posture. Headquartered in the United States, the company has established itself as a critical component of the modern security stack, serving a diverse range of enterprise clients who require real-time, actionable insights into the evolving threat landscape.
