GreyNoise Raises $15M in Series A Funding


Intelligence GreyNoisea Washington, D.C.-based cybersecurity company analyzing internet analytics traffic to separate threats from background noise, raised $15m in Series A funding.

The round, which brings total funds raised to date to $21 million, was led by Radian Capital with participation from CRV, Inner Loop, Stone Mill Ventures and Paladin Capital.

The company intends to use the funds to accelerate the development and delivery of its threat intelligence data solution, which helps security teams waste less time on irrelevant or innocuous activities, and focus more on targeted and emerging threats.

Led by Andrew Morris, Founder and CEO, GreyNoise leverages a global network of passive sensors to collect, analyze and label data about IP addresses that scan and attack the internet, saturating security tools with noise. GreyNoise data provides security teams with an early warning system for mass internet exploit attacks, real-time IP blocklists they can use to defend themselves, and context to quickly eliminate loud alerts .

GreyNoise is used by Global 2000 companies, governments, major security vendors and tens of thousands of threat researchers, including industry leaders such as Airbus, CenturyLink, The Intercontinental Exchange and multiple agencies US and NATO defense and intelligence. It is especially useful for companies that have a security operations center and are running a SIEM (Security Information and Event Management) or SOAR (Security Operations Analytics and Reporting) platform.
