GreyNoise Intelligence

GreyNoise Intelligence is a cyber threat intelligence and noise-reduction platform that collects, analyzes, and contextualizes internet-wide scan traffic to help cybersecurity teams filter out false alarms and focus on genuine security threats. By monitoring internet-scale network traffic across thousands of distributed honeypots and passive sensors, GreyNoise tracks the opportunistic bots, automated vulnerability scanners, research crawlers, and malicious actors that constantly bombard all public IP addresses. GreyNoise analyzes this massive dataset to categorize scanning hosts into benign actors, common scanners, and malicious infrastructure attempting widespread exploitation. This unique visibility allows enterprise SOC teams to distinguish between ubiquitous internet background noise and malicious cyber actors who are specifically targeting their organizational network infrastructure. GreyNoise provides high-fidelity threat indicators, contextual CVE tags, and trending exploitation metrics that reveal which vulnerabilities are actively being weaponized across the globe. Seamless integration with leading SIEM, SOAR, EDR, and firewall platforms empowers security teams to automate noise filtering, accelerate triage workflows, and proactively block emerging threat vectors before perimeter breaches occur.
