The Enterprise

Challenges

The customer needed certificates that don't expire, cryptography that survives the quantum era, and throughput that keeps a global production line moving — all delivered in a single quarter.

Certificates that last the life of the device

Embedded at manufacture, they cannot expire and cannot be replaced once the device leaves the factory floor.
01 LIFETIME

Quantum-ready cryptography from day one

Vendor-neutral, hardware-secured, and ready to evolve as NIST post-quantum standards mature toward 2030.
02 CRYPTOGRAPHY

Manufacturing-grade throughput

Any slowdown in the PKI translates directly to a slowdown on the production line. Performance was non-negotiable.
03 THROUGHPUT
The result was a secure, scalable, future-ready PKI – Purpose – Built to integrate with hardware manufacturing and enable trusted device identity at every stage of production.

ENGAGEMENT SUMMARY

ENCRYPTION CONSULTING · PKI SERVICES

Our

Solutions

Discovery before deployment. Technical sessions with key stakeholders mapped manufacturing workflows, scalability targets, and security goals. Four parallel workstreams, each addressing a specific requirement.

Capability 01

Lifetime validity

Certificates valid through 12/31/9999, standards-aligned with OCP, DICE, and IEEE 802.1AR for hardware permanently embedded at manufacture.

Capability 02

Hybrid cryptography

ML-DSA 87 paired with classical RSA for a graceful classical-to-quantum transition. No future re-issuance required when post-quantum standards mature.

Capability 03

Quorum-protected HSMs

FIPS 140-3 hardware modules with three-custodian access, redundant standby environments, and no single point of failure.

Capability 04

Precision governance

Per-operator issuance limits, path length constraints, custom SAN formats, scoped certificate profiles, and legally reviewed CP/CPS: built in, not bolted on.
The result was a secure, scalable, future-ready PKI — purpose-built to integrate with hardware manufacturing and enable trusted device identity at every stage of production.

The Overall

Business Outcome

Manufacturing speed is unlocked, every device leaves the line cryptographically verified, and the organization owns every step of the certificate lifecycle.

01

Manufacturing speed unlocked

Certificates are embedded in real time at the pace of the factory floor, with a full audit trail at every step.
02

Every device verified

Each device leaves the production line with a unique, tamper-evident identity. Unauthorized devices cannot enter the network.
03

Built for the long term

Post-quantum algorithms are live, disaster recovery is operational, and the PKI scales without re-architecture.
