Funding Details

Frenos, an AI-native OT security startup, announced a $1.52 million extension to its seed funding round. This latest investment increases the company's total funding to $6.4 million. The round was led by Momenta and Exposition Ventures, with additional participation from Riptide Ventures.

Strategic Use of Funds

New Product Launch: SAIRA Co-Work

Alongside the funding announcement, Frenos launched SAIRA Co-Work. This new AI reasoning agent is designed to provide evidence-based insights, assisting with complex investigations within operational technology environments.

Frenos's OT Security Platform

Founded in 2023, US-based Frenos offers an autonomous operational technology (OT) security assessment platform. This platform continuously validates the security posture of OT systems by utilizing a digital twin of the customer's network and SAIRA to conduct simulated penetration tests. The process validates attack paths, chains exploits, and prioritizes risks without impacting live operations.

Platform Advantages

Frenos states that its approach significantly reduces assessment time to minutes, eliminates downtime, requires no additional hardware or scanning, and is risk-free. Robert M. Lee, co-founder and CEO of Dragos and a Frenos advisory board member, noted that Frenos addresses the critical question of how an attacker can disrupt a process, a capability he considers rare in the industry.
