For years, PKI has been recognised as the foundation of digital trust, enabling secure identities, authentication, encryption and certificate-based security across enterprise environments. However, traditional PKI deployments were designed for a world of users, servers and applications—not billions of connected devices.

As organisations scale their IoT, OT and connected product initiatives, the economics and operational complexity of traditional PKI are increasingly becoming barriers to adoption. Large upfront licensing costs, overprovisioned infrastructure, complex deployment models and unpredictable certificate management expenses can make it difficult to extend device identity security across entire fleets.

At the same time, regulatory requirements, zero trust architectures, software supply chain security initiatives and emerging post-quantum considerations are driving greater reliance on certificate-based authentication. Organisations need PKI that is simpler to consume, easier to scale and aligned with modern cloud economics.

The future of PKI is shifting from a capital-intensive infrastructure project to a flexible, consumption-based security service—allowing organisations to establish trusted device identities from day one and scale securely as deployments grow.
