GreyNoise scores $15m in Series A haul

GreyNoise Intelligence, a firm that specialises in threat intelligence, has landed $15m in a Series A round headed by Radian Capital.

Also taking part in the funding round were CRV, Inner Loop, Stone Mill Ventures and Paladin Capital. Since it launched in 2017, CyberTech GreyNoise has raised a total of $21m.

According to Security Week, GreyNoise markets technology and data to help security teams and SOC analysts to cut through the noise of excessive alerts. The company manages a global network of massive sensors that ‘listens to the internet’ and identifies IP addresses that are mass scanning and crawling the internet.

“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,” claims Andrew Morris, GreyNoise founder and CEO.

The firm’s platform classifies and labels these IP addresses as malicious or benign, based on behaviour, intent and actor. Alongside the filtering of threat data, the GreyNoise platform is also able to provide early warnings about growing internet-wide attacks targeting commonly misconfigured systems and weakly-credentialed devices.

GreyNoise claims it plans to use the funding to expand its threat data collection capabilities and speed up go-to-market initiatives.

Tech giant Microsoft is set to acquire cyber threat analysis and research company Miburo for an undisclosed fee.
