RADICL raises $31m Series A led by Paladin for its autonomous security operations centre

What RADICL does

RADICL sells an autonomous virtual security operations centre, or vSOC, for small and medium-sized businesses in regulated or high-risk sectors, notably companies that support the US defence industrial base and critical infrastructure. SecurityWeek said the platform uses agentic operators to identify, assess and respond to attacks and provides defence-in-depth and managed compliance for both the customer and its managed service provider.

The company's website lists managed compliance services for CMMC and NIST 800-171 readiness, managed log analytics, 24/7 detection and response across endpoints, identities and networks, attack-surface management and security awareness training.

GovInfoSecurity described a platform that models machines, identities, users and infrastructure as entities and uses AI agents alongside human analysts.

Team and traction

Chris Petersen is co-founder and chief executive. He co-founded the security analytics company LogRhythm in 2002, spent nearly 17 years there and left in 2019 after Thoma Bravo became its majority owner, GovInfoSecurity reported. SecurityWeek said RADICL was founded in 2021.

RADICL has 41 employees, according to GovInfoSecurity. Petersen told that outlet the company grew eightfold year on year in its last fiscal year, with net revenue retention of about 130%. SiliconANGLE reported revenue growth of more than sevenfold from an undisclosed base. These are company-reported figures. SiliconANGLE said the company is incorporated as Radicl Defense Inc., and that the platform offers 24/7 monitoring, threat detection, investigation and incident response while helping customers meet CMMC and NIST SP 800-171 requirements. It named customers including Trenton Systems, VATN Systems, Barn Owl Tech, Bluesky Innovators and DIT-MCO International.

What the money is for

RADICL said it will develop its AI-native vSOC, launch new products and support market adoption. Petersen told GovInfoSecurity that the company has aggressive plans on the research and development side, covering AI model development, entity-based analytics and automation infrastructure, along with expanding customer acquisition and delivery capacity.

He told SiliconANGLE that small and medium-sized businesses have historically been left behind when it comes to robust security operations and defence-in-depth, because they cannot afford best-in-class technology or talent. He said the platform was built and designed to be AI-native from the ground up. He also said an AI-enabled threat tsunami is on the horizon for small and medium-sized businesses, and that it is imperative that those supporting US national security have better options to choose from.
