Keyfactor, a provider of trust infrastructure built for the AI and quantum era, has landed a strategic growth investment of more than $1bn, in a deal that underlines how urgent machine identity security has become for enterprises worldwide.
The round was led by Summit Partners, with existing backers Insight Partners and Sixth Street Growth set to retain substantial stakes once the deal completes.
The fresh capital will be directed towards accelerating Keyfactor’s international expansion, funding product development, growing its team and pursuing strategic acquisitions. Summit Partners managing directors Andy Collins and Colin Mistele will both take seats on the Keyfactor board when the transaction closes.
According to the company, four pressures are combining to push trust infrastructure onto boardroom agendas: identity sprawl driven by AI, ever-shorter certificate lifespans, tougher regulation and the shift towards post-quantum cryptography.
Machine identities now vastly exceed human ones and are multiplying at a pace that fragmented tooling and manual workflows cannot keep up with. Policymakers are adding to the pressure, with the White House issuing executive orders in June 2026 aimed at speeding the US transition to PQC before 2030.
Keyfactor’s answer is to consolidate these scattered challenges into a single platform. Its Trust Control Plane gives organisations centralised oversight of machine identities, cryptographic assets and trust systems, while automating lifecycle management and enabling consistent governance across cloud, on-premises and hybrid environments, covering devices, workloads and AI agents alike.
The company said it is scaling from a position of financial strength, citing accelerating year-over-year revenue growth alongside sustained profitability. It issues and manages billions of machine identities annually for over 2,500 customers, counting half of the largest banks in the US and Europe, 80% of top US retailers and more than 40% of the Fortune 100 among them. Earlier this year it gained FedRAMP certification, opening a cloud-based route to certificate lifecycle automation for US federal agencies.
Keyfactor CEO Jordan Rackie said, “Trust infrastructure has become the foundation that every enterprise, government agency, and AI-driven organization depends on, and Keyfactor is the platform built to manage it at scale. This investment is a powerful validation of what our team has built and where we are headed.
“Summit Partners shares our conviction that the opportunity in front of us has never been larger, and this partnership gives us the resources and runway to capture it. For our customers and partners, this is a moment of continuity and acceleration: the same leadership, the same mission, and an even stronger platform.”
