GreyNoise Intelligence, the cyber security company analyzing internet scanning traffic to separate threats from background noise, today announced that it has raised a $15 Million round of Series A funding led by Radian Capital. With participation from CRV, Inner Loop, Stone Mill Ventures and Paladin Capital, this brings the total of funding raised to date to $21 million. With this funding, GreyNoise will accelerate the development and distribution of its unique threat intelligence data solution, which helps security teams waste less time on irrelevant or harmless activity, and spend more time focused on targeted and emerging threats.

“Ask any SOC analyst and they will tell you that existing network security products aren’t cutting it. Security tools generate thousands of alerts from harmless events that need to be investigated, and alert fatigue causes missed threats and productivity issues. Our research and customer feedback has demonstrated that this is a largely solvable problem” explained Andrew Morris, Founder and CEO, GreyNoise. “To address these issues, GreyNoise separates irrelevant internet noise from emerging threats. This enables security teams to quickly eliminate noisy security alerts from the SOC, identify and block mass exploit attacks, hunt for compromised systems, and prioritize patching. We offer security teams a better way to stay ahead of large opportunistic attacks such as Log4J.”

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 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.

“We’re thrilled to invest and partner with GreyNoise, a company that has taken an innovative approach to tackling the enormous issue of mass exploitation attacks and internet noise,” said Dave Sack, Principal, Radian Capital. “GreyNoise has created a category-defining new product that helps security teams to sort out irrelevant alerts and focus their time and energy on targeted and emerging threats. With applicability to almost any security organization, the market for this solution is enormous and growing quickly.”

GreyNoise is trusted by Global 2000 enterprises, governments, top security vendors and tens of thousands of threat researchers, including industry leaders such as Airbus, CenturyLink, The Intercontinental Exchange and multiple US and NATO Defense and Intelligence agencies. It is particularly valuable for enterprises that have a Security Operations Center and run a Security Information and Event Management (SIEM) or Security Operations Analytics and Reporting (SOAR) platform. GreyNoise is also committed to supporting the broader security community via its free Community plan, which currently serves security analysts at over 10,000 organizations.
