OT Security Startup Frenos Raises $1.52 Million

The company will use the fresh investment to grow its customer success and AI R&D teams. The post OT Security Startup Frenos Raises $1.52 Million appeared first on SecurityWeek .

SecurityWeek reports that AI-native OT security startup Frenos has raised $1.52 million in a seed extension round, bringing its total funding to $6.4 million.[2][3] The company plans to use the investment to expand its customer success team and grow its AI R&D capabilities for its autonomous OT security assessment platform.[1][2] From a RealGround perspective, increased dependence on an AI-native OT security vendor introduces AI supply chain risk for critical infrastructure operators, including opaque model behavior, limited visibility into training data, and potential vulnerabilities in the vendor’s AI development lifecycle. Organizations integrating Frenos or similar platforms into their OT environments should apply structured AI supply chain due diligence and SBOM-style transparency to models, data flows, and update mechanisms to ensure that third-party AI components do not become a path for compromise.
