Keyfactor Secures $1B+ Growth Investment for AI, Quantum Security

Keyfactor announced a strategic growth investment exceeding $1 billion led by Summit Partners to accelerate development of its Trust Control Plane and expand global operations. Existing investors Insight Partners and Sixth Street Growth will remain significant stakeholders. The company did not disclose detailed deal terms or the exact amount beyond stating the capital tops $1 billion.

The funding is targeted at scaling the Trust Control Plane, which centralizes visibility and automates lifecycle management for machine identities across cloud, hybrid and on-premises environments. Keyfactor said it will use the proceeds for product development, geographic expansion, hiring and potential strategic acquisitions.

Keyfactor offers an end-to-end platform that discovers, issues, renews and revokes cryptographic keys and certificates used to authenticate machines, devices and software agents. The company reports it manages billions of machine identities each year and serves more than 2,500 organizations worldwide. Machine identities include TLS certificates, code-signing keys, SSH keys and other credentials used by servers, devices, containers and software to prove identity and secure communications.

Regulatory and technical developments are increasing demand for the company’s services. In June 2026, the White House issued an executive order directing an accelerated federal transition to quantum-safe cryptography with a 2030 goal. Shorter certificate lifespans and new requirements for governing autonomous AI agents have put pressure on enterprises to modernize machine identity management.

Andy Collins, Managing Director at Summit Partners, commented: “In our view, the convergence of post-quantum preparation, agentic AI governance, shrinking certificate lifespans, and evolving regulatory expectations is creating an increasingly urgent need for a unified, enterprise-grade platform.”

Loss of visibility or failures in lifecycle automation can cause outages or security incidents. Interest in quantum-resistant cryptography has risen because future quantum computers could weaken widely used public-key algorithms, prompting governments and industry to plan transitions to new key types and protection methods.
