Government agencies represent a treasure trove of information that hackers want. Protecting your assets and constituents from cyber threats is incredibly challenging in an environment of cloud-scale attacks, cyber workforce skill shortages, and highly motivated adversaries. In particular:
Using a global network of passive sensors, GreyNoise collects, analyzes, and labels data on IPs that scan and attack the internet, saturating security tools with noise. GreyNoise attack telemetry goes beyond traditional threat intelligence: our data provides security teams with an early warning system for mass exploitation attacks on the internet, real-time IP block lists they can use to defend themselves, and context to quickly eliminate noisy alerts.
GreyNoise helps SOC analysts and incident responders investigate and triage security alerts more quickly and effectively by separating targeted activity from irrelevant or harmless background noise.
And for security engineering teams building correlation rules and automation in SIEM and SOAR, GreyNoise data can be used to automatically de-prioritize and suppress noisy alerts. One GreyNoise customer reduced Splunk alerts by 25%.
GreyNoise provides an early warning system to identify when a vulnerability is being mass exploited at scale in the wild. This information is a critical data point for patch prioritization, as well as knowing when to “break the glass” and trigger emergency patching protocols.
During a mass exploitation attack, security teams are typically scrambling to fix the vulnerability, block ongoing attacks, and find early signs of compromise. GreyNoise provides dynamic IP blocklists, curated by CVE, that allow organizations to defend themselves during the early "window of exposure" from these attacks...and to hunt for known attacker IPs.
GreyNoise helps threat hunters and intelligence analysts in two key ways: visibility and deep context into mass scanning IP addresses that form the early-stage attack infrastructure for many of today’s most dangerous cyber threats; and the ability to filter out noisy or harmless IP addresses from SIEM or NetFlow-based threat hunting activities.
“GreyNoise is helping the DoD’s Defense Innovation Unit (DIU) identify and understand internet-wide scan and attack activity. This $30 million production contract will allow the GreyNoise platform to be purchased and utilized by all DoD organizations over a five-year period. GreyNoise will enhance cyber threat detection and intelligence-gathering capabilities across the DoD and other branches of the US government, and enable security analysts to focus their valuable time and energy on legitimate threats."
