GreyNoise Platform: Real-Time Threat Intelligence for the Network Edge

GreyNoise operates the Global Observation Grid, a global network of more than 5,000 sensors across 80 countries that mimic the edge infrastructure attackers target. These sensors capture the traffic sent to them as attackers scan the internet, probe exposed systems and attempt to exploit vulnerabilities. From that activity, GreyNoise identifies the IP addresses involved, the CVEs being targeted and the callback infrastructure embedded in exploit payloads. Teams can also deploy sensors on their own edge to see what attackers are doing after initial access and analyze the artifacts captured from those sessions. As AI collapses time-to-exploit, these observations show defenders how attack activity is developing while new vulnerabilities are being weaponized.

SEE EXPLOITATION AS IT STARTS GreyNoise tracks which CVEs are under attack right now, how many distinct IP addresses are attempting each one, and when the activity began. Patch priorities can follow observed attacker behavior rather than severity scores alone. CISA KEV status is included for compliance reporting.

FIND COMPROMISED DEVICES C2 Detection identifies devices making outbound connections to known command-and-control infrastructure. Callback IPs carry a three-stage classification - Unconfirmed, Stage 1, Stage 2 - indicating how serious each one is, along with malware family attribution and file hashes.

TRIAGE AND INVESTIGATE ALERTS FASTER GreyNoise identifies the IP addresses that are scanning the internet indiscriminately, along with the known-good business services behind routine false positives (CDNs, public DNS and NTP, SaaS APIs, update servers), so analysts can set that traffic aside and spend their time on the alerts that pose a real threat.

PUSH INTELLIGENCE INTO ENFORCEMENT Dynamic blocklists feed straight into a firewall for real-time blocking of emerging threats.

HOW YOU CONSUME IT Intelligence is delivered through an API, a search and analytics query interface, dynamic blocklists, alerting, and out-of-the-box integrations with widely used SIEM, SOAR, firewall and threat intelligence platforms. Select datasets are also offered as bulk data delivery.

WHAT GREYNOISE OBSERVES, AND WHAT IT DOES NOT GreyNoise reports attacker attempts and techniques observed against its own sensors. It does not confirm compromise of any specific organization, and IP geolocation indicates where a server sits, not where an operator sits.

PACKAGING GreyNoise customers purchase one platform license (Standard, Advanced, or Elite), which sets data refresh rate, historical recall depth, alert and blocklist limits, and support response times, plus at least one core intelligence module (Triage, Investigate, or Hunt), which determines the available data fields. Modules nest: Hunt includes everything in Investigate, which includes everything in Triage. C2 Detection, Vulnerability Prioritization and Business Services are separately licensed and attach to any paid platform tier.
