Rein Security
Rein Security is an Israeli private cybersecurity startup focused on reducing software supply-chain risk through proactive dependency and package security.
Visit WebsiteCompany Overview
Rein Security builds software supply-chain defense capabilities for organizations that rely on open-source packages, third-party code, and fast-moving development pipelines. The company focuses on helping security and engineering teams identify exploitable dependency exposure before it reaches production systems.
The startup is privately held and venture-backed, with reported seed financing in 2026. Rein is headquartered in Tel Aviv and fits the profile of early-stage Israeli cyber companies attacking critical infrastructure risk in modern software ecosystems.
Dual-use relevance is high: software supply-chain integrity is essential across commercial platforms, critical infrastructure, and defense-supporting systems that depend on trusted code provenance and resilient build pipelines.
Dual-Use Assessment
Supply-chain code security is dual-use for enterprise software resilience and defense-adjacent mission-system software assurance.
