Industrial organizations need more than certificate issuance. They need enrollment, deployment, renewal, trust management and revocation across heterogeneous devices, applications and operational domains. Trustpoint Labs helps design, integrate and automate these certificate lifecycle workflows in real OT environments.
We work vendor-independently with existing PKI platforms, industrial devices and applications. Trustpoint is an open-source certificate management platform that can complement enterprise PKI rather than replace it outright.Explore the open-source project
Whether you need to connect an existing certificate authority to industrial devices, automate renewal, or establish machine identities for a new product, we structure the work around your technical constraints and agreed outcomes.
We assess devices, applications, existing PKI, trust boundaries, network restrictions and security requirements. Where relevant, we consider applicable standards and regulatory requirements when designing the integration.
We configure Trustpoint, integrate connected PKI systems, implement enrollment and lifecycle workflows and develop custom connectors or automation where necessary. Delivery can be independent or in collaboration with customer teams.
We validate the integration against project-specific acceptance criteria, including functional behavior, device interoperability and certificate lifecycle workflows, and prepare the deployment for the agreed operational environment. Extensive security assessments, penetration tests and formal conformity assessments require separate agreement.
We document the implementation, provide operational guidance and conduct a project-specific handover. The customer or their designated provider remains responsible for operations. Optional support and SLA agreements, as well as additional workshops or training, are available separately.
Industrial certificate automation must work across different devices, vendors, authorities and operational networks. We take a vendor-independent, open-standards-first approach to connecting IT and OT infrastructure. Trustpoint can serve as a local certificate lifecycle layer, an enrollment and renewal coordinator, or a companion to an existing issuing PKI. The actual architecture depends on device capabilities, network segmentation and connectivity requirements.Explore our application areas
CMP and EST integration for automated certificate enrollment and lifecycle workflows.
Connect applications and automation workflows to Trustpoint through supported APIs.
Integrate Trustpoint into OPC UA certificate-management and GDS-based environments.
Integrate Trustpoint with external CAs, RAs and certificate management platforms, including relevant architecture, configuration and interface workflows.
Implement secure onboarding and certificate lifecycle workflows for connected devices across our application areas.
Integrate legacy devices and systems in segmented, restricted-connectivity or air-gapped environments, including cases without modern enrollment interfaces.
Industrial operators and equipment manufacturers need certificate policies, device onboarding strategies and trust models that fit long-lived OT assets. We help assess the current situation, identify integration constraints and develop a practical industrial PKI architecture without requiring a specific PKI vendor or deployment platform.
Define certificate authorities, registration flows, trust boundaries and lifecycle responsibilities across devices, machines and operators.
Assess relevant technical requirements and integration options for certificate-based security, including IEC 62443-related architecture considerations where applicable. Formal compliance assessment is separately scoped.
Assessment scope and report format are agreed for each engagement. Consulting can be delivered independently or as the first phase of an engineering project; implementation is scoped separately. Discuss an industrial PKI assessment
Legacy devices, proprietary interfaces and specialized operational workflows do not always fit standard certificate enrollment mechanisms. We develop customer-specific connectors, device integrations and automation for the agreed PKI architecture. Where Trustpoint is used, reusable improvements can be contributed to the open-source project; proprietary extensions can remain separate, subject to agreed licensing and ownership terms.
Integrate Trustpoint into customer-specific products and branded solutions. Each engagement defines its product workflows, branding, licensing, ownership and handover. Support for modified builds, ongoing maintenance and compatibility updates are not included automatically and must be agreed separately.
Custom extensions are validated against the agreed scope and acceptance criteria. Ongoing maintenance and compatibility updates can be arranged separately.
Examples of problems we can address using Trustpoint or other suitable PKI technologies. These are illustrative applications, not customer project references.
Connect industrial certificate workflows with existing enterprise CAs, registration processes and lifecycle policies, using Trustpoint where suitable.
Replace manual certificate provisioning with enrollment and renewal workflows using EST, CMP or device-supported alternatives.
Reduce manual certificate handling by integrating compatible OPC UA applications with GDS-based certificate-management workflows.
Address legacy devices lacking standard enrollment interfaces with validated device-specific workflows, including Web-UI Automation where supported.

Typical deliverables may include an agreed target architecture, configured deployment and interfaces, functional and interoperability validation results, technical documentation and handover. Deliverables and acceptance criteria are agreed for each assignment; source code and development assets are handed over as contractually agreed.
Designs and integrates industrial PKI architectures, automates machine identities and develops custom solutions using Trustpoint or other suitable technology.
Provides agreed technical assistance, troubleshooting and incident resolution under optional support or SLA contracts. The customer or designated operator retains operational responsibility; managed operations are not currently offered.
