Industry Challenge
- Modern manufacturing environments rely on millions of PLCs, sensors, robots, and OT systems that were never designed for today’s identity and key-management demands.
- Internal SCADA, historian, and DCS traffic still depends on long-lived certificates that expire silently and require a PKI that OT teams cannot realistically operate.
- Sensitive operational data — historian logs, production recipes, IP assets — is encrypted with keys tracked manually in binders, spreadsheets, or ad-hoc HSM scripts.
- IEC 62443 requires provable identity and key governance, but manual processes cannot deliver the automation, auditability, or scale required across the factory floor.
Amera® Solution
Certificate-Free Device Identity and Automated Key Governance for OT
- Deterministic, hardware-rooted identity for PLCs, sensors, and edge devices — no internal CA, no certificate renewal, no PKI infrastructure on the OT network.
- SCADA, historian, and DCS connections use continuously rotating symmetric keys instead of static TLS certificates, eliminating expiry-driven outages.
- AmeraKey® governs encryption keys for historian databases, recipe stores, and IP repositories with deterministic derivation, rotation policies, and audit-ready logs.
- All identity and key operations run inside the OT network — no cloud dependency, no external trust chain, no exposure of operational systems.
Use Cases
Replacing Per-Device X.509 Certificates on OT Networks
Managing certificate lifecycle for thousands or millions of PLCs and sensors is operationally impossible. AmeraKey® replaces per-device certificates with deterministic, hardware-rooted identity that never expires and requires no CA infrastructure.
Eliminating PKI for Internal SCADA/OT Encryption
Internal SCADA, historian, and DCS systems often run on long-lived TLS certificates that expire silently. AmeraKey® replaces these certificates with auto-rotating symmetric transport keys, removing renewal calendars and reducing OT attack surface.
Encryption Key Governance for Operational Data Stores
Historian logs, production recipes, and IP repositories contain highly sensitive operational data. AmeraKey® governs all data-at-rest keys with deterministic derivation, rotation, and audit logging — replacing manual HSM scripts and binder-based key tracking.
Key Benefits
No internal CA or certificate lifecycle
Eliminates PKI from the factory floor and removes a major operational and security burden.
Hardware-rooted device identity
Deterministic identity derived from device characteristics — cannot be cloned or extracted.
Auto-rotating transport encryption
Keys rotate continuously, eliminating silent certificate expiry and reducing lateral-movement risk.
Automated key governance for sensitive data
AmeraKey® manages the full lifecycle of data-at-rest keys for historian, IP, and recipe stores.
IEC 62443-aligned auditability
Every identity and key event is logged and exportable as compliance evidence.
Positioning Statement
Amera® secures the modern factory floor with certificate-free device identity and automated key governance — eliminating internal PKI while protecting every PLC, sensor, and operational data store in alignment with IEC 62443.
