Managed
PKI
A complete Public Key Infrastructure operated as a managed service — designed for machine identity, device identity, IoT platforms, industrial systems, and secure software ecosystems.
Machine Identity Platform
PKI built for machines,
not just websites
The NTS Managed PKI service is designed specifically for machine identities, device certificates, secure boot, code signing, token signing, and Zero Trust infrastructure — not traditional web TLS certificate management.
Built on enterprise PKI technology and hardware security modules, the service includes PKI architecture design, certificate authority operations, certificate lifecycle automation interfaces, and long-term PKI governance support.
Trust Lifecycle
How trust flows through
the NTS platform
From the Root CA trust anchor through to the devices and software that consume cryptographic trust — every layer is connected.
Key Differentiators
What makes NTS Managed PKI different
Multi-Cloud & Hybrid CA
Supports hybrid PKI architectures with AWS Private CA, Azure Cloud PKI, Google CAS, and on-premises CAs — while maintaining a single customer-controlled Root of Trust.
Crypto Agility & PQC
Post-quantum cryptography migration is a core part of the Managed PKI strategy — not an afterthought. HSM platforms support new cryptographic algorithms as they become available.
Application-Driven PKI
Integrates directly with PKI Application Services — EST Gateway, Secure Boot, Code Signing, Token Signing — making the environment application-driven rather than certificate-driven.
