About Finite State

Finite State is the Product Security Automation Platform for connected devices, bringing firmware and binary analysis, source intelligence, SBOM management, vulnerability prioritization, and security and compliance workflows into one platform.[11]

Finite State says its Product Security OS unifies firmware, binaries, source code, and compliance evidence into autonomous, review-gated workflows. The Finite State Product Security OS replaces manual evidence assembly with workflows that transform code, compiled components, firmware, and documentation into continuous security and compliance assurance. Across the Finite State Platform, Assurance Studio, AgentOS, and Finite State Copilot, teams move from firmware, binaries, source, and documentation to SBOMs, VEX, verification evidence, and audit-ready reports.[1][3][4]

The Finite State Platform analyzes firmware, binaries, source code, supplier SBOMs, and third-party findings to generate SBOMs, vulnerability context, reachability insights, and a portfolio-wide record of product risk. Finite State prioritizes vulnerabilities using reachability, exploit intelligence, and product context so teams focus on real exposure. On its home page, Finite State states that 40.5% of findings analyzed for reachability since 2024 were confirmed unreachable. The company also describes SBOMs and software inventory across firmware, binaries, and source code, with support for 50+ binary instruction set architectures.[1][4]

On compliance, Finite State says AgentOS makes compliance a living, continuous workflow, grounded in the same software evidence used for security and risk decisions. Finite State describes exportable evidence packs for CRA, FDA §524B, CE RED, and Cyber Trust Mark. Its compliance workflows include control and requirement mapping, verification planning and evidence collection, audit-ready reports, and release readiness checks such as a what-changed analysis since the previous release.[12]

Finite State describes its CRA managed service as helping manufacturers achieve EU Cyber Resilience Act compliance through automated SBOMs, risk assessments, and continuous vulnerability monitoring. The customer's team remains in control of remediation decisions, regulatory reporting, and product declarations.[13][14]

For integration, Finite State says product security checks can be embedded directly into GitHub Actions, GitLab CI, Jenkins, and existing release workflows. Finite State also points to APIs, CLI tooling, IDE integrations, and ticketing workflows for engineering teams.[1]

Finite State describes its audience as teams shipping connected, regulated products. Its pages address automotive organizations, manufacturers, and medical device manufacturers. Its resource page states that the Product Security OS helps medical device manufacturers meet all six FDA 524B(b) cybersecurity requirements. Finite State lists Sharon Hagi as its Chief Security Officer.[1][3][4][6][14][15][16][17]
