GreyNoise: The Signal in the Noise
How a 65-person team is silencing the internet's background radiation for security teams worldwide
Every day, security teams drown in millions of alerts from automated internet scans. GreyNoise doesn't just filter the noise—it identifies the attacks that actually matter. With 523,000 monthly visitors and a laser focus on real-time edge threat detection, this 65-person powerhouse is solving signal-to-noise in cybersecurity.
"They're not competing with SIEMs—they're making them irrelevant for commodity threats."
The Silent Majority Problem
GreyNoise targets the 95% of security alerts that are false positives from internet-wide scanning. Their users aren't SOC analysts drowning in noise—they're threat hunters and detection engineers who need to know: 'Is this attack targeting me, or just the entire internet?' The 49% direct traffic proves these are power users who know exactly what they need.
The Growth Paradox
Here's the counterintuitive part: GreyNoise thrives on being a utility, not a platform. With 35% organic search and keywords like 'greynoise ip check' driving 8,680 monthly searches, they've become the de facto 'Ctrl+F' for internet threats. The $11.9M revenue on 65 employees shows a lean, product-led motion that enterprise security teams can't live without.
The tech stack tells the story of a modern, fast-moving security startup: Vite for speed, Tailwind for design velocity, and jQuery (yes, still) for the legacy bits that work. Their social presence on TikTok of all places shows they're not your grandfather's security vendor—they're meeting analysts where they are.
- They don't replace your SIEM—they make it smarter by filtering out internet background radiation
- They don't chase zero-days—they identify the mass-exploited vulnerabilities before you get hit
- They don't require a 6-month deployment—API-first design means value in minutes, not months
The Bottom Line
GreyNoise is the anti-platform play in a platform-obsessed market. They win by doing one thing better than anyone: telling you which threats are real and which are just noise. In a world of infinite alerts, that's worth $11.9M and counting.
