$15m Series A funding was raised by GreyNoise Intelligence, a Washington DC-based cyber security firm that analyzes internet scanning traffic to distinguish threats from background noise.
The round, which brings the total of funding raised to date to $21m, was led by Radian Capital with participation from CRV, Inner Loop, Stone Mill Ventures and Paladin Capital.
The company plans to use the funds for the acceleration of the development and distribution its threat intelligence data system. This helps security teams spend less time on innocuous or irrelevant activity and more time on emerging threats and targeted activities.
GreyNoise is led by Andrew Morris, the founder and CEO. GreyNoise utilizes a global network passive sensors to collect and analyze data on IPs that scan or attack the internet. This noise saturates security tools. GreyNoise data gives security teams an early warning system for internet exploitation attacks, real-time IP block list they can use to protect themselves, and context to rapidly eliminate noisy alerts.
GreyNoise can be used by Global 2000 companies, top security vendors, and tens to thousands of threat researchers. This includes industry leaders like Airbus, CenturyLink and The Intercontinental Exchange, as well as numerous US and NATO Defense and Intelligence Agencies. It is especially valuable for companies that have a Security Operations Center and operate a Security Information and Event Management platform (SIEM), or Security Operations Analytics and Reporting platform (SOAR).
