PKI Application
Services
Transform PKI from a backend certificate system into a complete trust platform for devices, software, and digital services. Achieve regulatory compliance and meet industrial cybersecurity standard requirements with PKI-secured product lifecycle management.
Overview
Building trust for devices, software and industrial systems
Connected devices, industrial systems, and cloud services need trust. Devices must prove their identity, software must be authentic, and systems must communicate securely.
Regulations and industrial cybersecurity standards are now pushing organisations to implement cybersecurity controls systematically. Nordic Trust Services provides PKI Application Services that turn cryptography into practical, deployable security solutions for manufacturing, IoT, industrial systems, and enterprise environments.
EST Gateway — Automated Certificate Lifecycle Management
Managing certificates manually does not scale in IoT, industrial, or cloud environments. Devices, servers, and applications need certificates automatically and securely.
The NTS EST Gateway provides a secure interface for devices and systems to request, renew, and manage certificates. It enables automated identity provisioning during manufacturing, secure certificate renewal in the field, and integration with DevOps and enterprise identity systems.
- IoT device identity provisioning
- Server & container certificate automation
- Manufacturing provisioning systems
- Industrial device authentication
- Secure device onboarding
Secure Boot & Chain of Trust — Ensuring Devices Only Run Trusted Software
Secure Boot ensures that a device starts only with trusted and authorised software. Each stage of the boot process verifies the next stage using digital signatures. If any component has been modified or is not trusted, the device will not boot.
This prevents firmware tampering, unauthorised modifications, and many supply-chain attacks. Secure Boot is increasingly expected in industrial devices, connected products, and critical infrastructure environments.
- Embedded Linux devices
- Industrial controllers
- Network equipment
- IoT gateways
- Robotics & automation systems
Code Signing — Protecting Firmware, Software and Updates
Code Signing ensures that software and firmware originate from a trusted source and have not been modified. Without code signing, attackers can distribute malicious firmware or software updates that appear legitimate.
Signing keys are stored securely in Hardware Security Modules and integrated into build pipelines and release processes, enabling organisations to build a secure software supply chain.
- Firmware signing
- Software release signing
- Secure update systems
- Linux kernel module signing
- Container image signing
- DevOps pipeline integration
Token Signing — Secure Authentication, APIs and Digital Transactions
Modern systems rely on authentication tokens, API tokens, and machine-to-machine authentication. These tokens must be signed and trusted to prevent impersonation and unauthorised access.
The NTS Token Signing service provides secure signing for JWTs, API tokens, and identity tokens. Signing keys are protected in certified high-availability Cloud HSMs, integrated with identity providers, API gateways, and application platforms.
- OAuth2 / OpenID Connect token signing
- API gateway authentication
- Device authentication tokens
- Service-to-service authentication
- Digital identity & verifiable credentials
Regulatory Alignment
Responding to regulation and
industrial security requirements
Cybersecurity regulation and industrial standards are increasingly requiring organisations to implement secure development, software integrity, device identity, and lifecycle security controls.
EU Cyber Resilience Act
Secure-by-design, software integrity, protection against tampering, secure software updates, and supply chain security controls.
NIS2 Directive
Identity management, secure communications, access control, lifecycle management, system integrity, and cryptographic controls.
IEC 62443
Industrial cybersecurity framework — device identity, authentication, certificate management, secure boot, and trusted components for industrial control systems.
