Managed
Root CA
A dedicated, secure, and auditable offline Root Certificate Authority — operated by NTS as your trust anchor for enterprise PKI, IoT, device identity, software signing, and secure infrastructure systems.
Root of Trust
Who controls the Root of Trust controls the infrastructure
The most important strategic decision in any PKI architecture is not where certificates are issued, but who controls the Root of Trust, the key material, and the governance processes.
With NTS Managed Root CA, it is always the customer that controls the keys and governance processes — not the cloud provider, not the CA vendor. Your Root CA, your trust.
Architecture
Hybrid & Multi-Cloud Root CA Architecture
Your organisation controls its own Root CA. The Root CA signs multiple issuing CAs across any cloud or on-premises environment — all chaining back to the same trust anchor.
Strategic Control
Why cloud PKI alone is not enough
Public cloud certificate authority services provide scalable certificate issuance — but when the entire trust infrastructure is built inside a single cloud provider, strategic risks emerge over time.
Cloud independence
Ability to migrate services between cloud providers without rebuilding trust infrastructure. Certificate hierarchies and device identities remain portable.
Key control
You control the Root CA lifecycle, cryptographic keys, certificate policies, and governance processes — not your cloud provider.
Long-term stability
IoT and industrial systems operate for 10–20 years. Trust infrastructure decisions made today directly impact future migration feasibility and PQC transition.
