Noise Letter April 2026

Summary: GreyNoise launched Project Swarm, a community-driven initiative that opens its deception platform to the global security community so defenders can deploy sensors on their own infrastructure and capture real attacker traffic targeting their edge. Participants can use the collected payloads, headers, and full session data for their own research, and compare their sensor traffic against the GreyNoise global baseline to see what is uniquely targeting them versus what is hitting everyone.
Bottom line: The pitch rests on a gap no single organization can close alone: without a shared baseline, you cannot tell traffic aimed specifically at you from commodity scanning hitting everyone, and that distinction is what separates a real targeting signal from background noise.
