Keyfactor, which helps organizations connect humans, machines, and AI with cryptographic security, has secured a strategic growth investment exceeding $1 billion.

The massive capital injection comes as enterprises are grappling with what is sometimes described as “identity sprawl“, where machine identities can significantly outnumber human identities.

Rather than relying on isolated, fragmented security tools, Keyfactor offers an end-to-end platform called the Trust Control Plane. The unified platform provides centralized visibility into cryptographic assets and automates the lifecycle management of machine identities across cloud, hybrid, and on-premises environments and safeguarding everything from standard devices to autonomous AI agents.

The newly injected capital is earmarked to accelerate Keyfactor’s global operations, advance product innovation, expand its geographic footprint, scale its team, and fund potential strategic acquisitions.

The funding round was led by growth equity firm Summit Partners.
