Keyfactor, a provider of enterprise encryption and digital identity management software, has secured a strategic growth investment exceeding $1 billion from Summit Partners, with participation from Insight Partners and Sixth Street Growth.
The Cleveland-based company manages cryptographic keys, certificates, and code signing infrastructure for large enterprises. The investment signals growing demand for what Keyfactor calls trust infrastructure, particularly as organizations prepare for post-quantum cryptography standards and AI-driven security requirements.
The company said the capital will accelerate product innovation, geographic expansion, and go-to-market initiatives. Keyfactor’s platform helps enterprises automate certificate lifecycle management and protect machine identities across hybrid cloud environments.
The deal represents one of the largest cybersecurity investments of 2026, reflecting the critical importance of encryption management as enterprises face increasingly complex regulatory and threat landscapes. Keyfactor has been on a growth trajectory since its founding and previously raised funding from Insight Partners in earlier rounds.
