GreyNoise Intelligence has launched Command and Control Detection, a new intelligence module designed to identify active cyber compromises using outbound network traffic data.
GreyNoise’s launch of its C2 Detection platform comes as government and industry leaders prepare to address evolving cyberthreats at upcoming forums. Register now for the 2026 Cyber Summit on May 21 to connect with experts and exchange perspectives on zero trust, AI in cyber defense and other topics in the evolving cyber landscape.
What Is GreyNoise C2 Detection?
The company said Tuesday the capability is designed to help security teams identify compromised devices earlier, prioritize response actions and support investigations by providing visibility into malware hashes, family classifications and callback infrastructure associated with attacker activity.
C2 Detection analyzes outbound network telemetry to identify communication between compromised devices and attacker-controlled infrastructure. GreyNoise said the module delivers post-exploitation visibility by matching outbound traffic against a continuously updated dataset of malware-hosting IP addresses and confirmed C2 servers.
The system provides insight into attack behavior, including payload delivery, binaries downloaded, external servers used for command and control and commands associated with those sessions.
GreyNoise said the module generates a signal indicating the severity of each match, allowing security teams to assess risk and determine whether an internal device may have been compromised based on its communication with known malicious infrastructure.
What Did GreyNoise Leaders Say About C2 Detection?
GreyNoise CEO Ash Devata said edge devices have become frequent targets and that visibility into post-compromise activity has been limited.
“GreyNoise has always been one of the most authoritative sources on inbound network threats. With C2 Detection, our customers can not only identify who’s probing their perimeter, but whether a device is already compromised and who it’s phoning home to,” Devata said.
Corey Bodzin, chief product officer at GreyNoise, said the new capability addresses a gap in detecting post-exploitation activity on edge devices.
“C2 Detection surfaces that activity, and empowers security teams to take action faster,” Bodzin said.
What Does GreyNoise Do?
GreyNoise is a cybersecurity company that provides threat intelligence designed to help security teams identify and prioritize internet-wide attack activity targeting network edge systems. The company operates the Global Observation Grid, a deception network of over 5,000 sensors deployed across more than 80 countries that observe and classify attack activity in real time.
In March, GreyNoise appointed Mike Habte, a federal technology sales and business development executive, as director of federal sales to support the company’s growth strategy across defense, intelligence and civilian agencies.
