Public Key Infrastructure (PKI) Services

Why Consider PKI Early in the Project Lifecycle?

Integrating PKI at the beginning of your development cycle ensures secure, compliant, and maintainable connected products. Delaying it can introduce challenges that are difficult and costly to resolve later. Development teams can avoid implementing temporary workarounds like hardcoded keys or manual certificate handling, which are difficult to update and expose systems to security risks. Operations teams benefit from structured certificate lifecycle management that supports bulk provisioning, revocation, and renewal without disrupting services. Compliance teams can produce clear audit trails and manage cryptographic assets centrally, simplifying homologation and regulatory approval processes.

Value of a Trusted PKI Partner

Teaming up with an experienced PKI Service provider helps you simplify the process of establishing cryptographic infrastructure, speed up deployment, and ensure compliance. It enables fast onboarding of connected devices with secure identities and automates certificate lifecycle management.

Device Identity Verification

Issue and manage digital certificates to authenticate ECUs, gateways, and edge devices.

Secure Firmware Signing

Sign OTA updates, Firmware, and image to establish end-to-end integrity and authenticity.

Built-In Compliance

Built-In Security Controls

Secure physical and logical access control, regular penetration testing, continuous monitoring, detailed logging, regular audits, and quick incident response are pillars of our secure solution.

Why diconium?

Our engineers and architects build compliance-focused PKI solutions across mobility and IoT. One such deployment enabled 20,000+ secure tokens for 100+ users in 5 countries.

Our PKIaaS Implementation Approach

We offer two delivery models. In the fully managed model, we handle the complete PKI lifecycle, including infrastructure provisioning, certificate management, and compliance.

In the client-driven model, your team builds on top of our secure backend, using our APIs, HSM as a Service, and cryptographic components.

Both models are supported by expert engineering, continuous validation, and long-term maintenance options.

Our comprehensive PKI offerings include:

Build and manage a custom Public Key Infrastructure

HSM as a Service (FIPS-compliant, API-accessible)

Secure firmware signing enabling OTA updates

Development support for custom PKI integration

PKI validation and penetration testing services

Ongoing support, monitoring, and maintenance

FAQ

What are Public Key Infrastructure Services?

Public Key Infrastructure Services go beyond basic certificate issuance.

They provide a complete framework with HSM servers as a foundation for managing cryptographic trust. It spans across certificate authority operations, secure key storage, revocation mechanisms , and automation of identity provisioning at device and application scale.

These services form the operational foundation for scalable, policy-driven security in connected environments.

What do you offer as part of building and managing a custom Public Key Infrastructure?

We design and operate Public Key Infrastructure (PKI) systems that are purpose-built for your organization’s security and compliance landscape. From initial architecture to ongoing lifecycle management, we deliver a comprehensive service that minimizes operational complexity.

Our services include:

Architecture and deployment of scalable backend infrastructure

Role-based identity and access management tailored to your organizational policies

Custom admin portals and interfaces, developed on request

Seamless integration with your business processes and existing systems

Security andpenetration testing

Ongoing maintenance and operational support to ensure reliability and trust continuity

What’s included in Development support for custom PKI integration?

Our security engineering team works closely with your developers and architects to accelerate PKI integration and modernization. Whether you're building a new trust layer or retrofitting legacy systems, we provide expert guidance and technical enablement every step of the way.

Our support includes:

Architecture reviews and deployment planning for PKI systems

Assistance with infrastructure setup and configuration

Ideal for teams automating certificate workflows, scaling secure access, or embedding PKI into new digital products

Why is PKI critical in automotive and IoT applications?

PKI secures over-the-air updates, enables secure communication, and ensures only authenticated software runs on connected devices. This helps organizations meet compliance and safety requirements.

Does Diconium offer HSM as a Service?

Yes. Our HSM as a Service offering provides secure, API-accessible key management backed by certified hardware, suitable for signing firmware and managing sensitive keys.

Here’s what you get:

API-first access to perform encryption, key generation, signing, and certificate issuance

FIPS-certified cryptographic hardware without the need to own or manage it

Audit logging, backup, and monitoring to support compliance and traceability

Optimized for agile and DevSecOps environments that demand flexibility and speed

Designed for scale, from embedded systems to enterprise-grade PKI architectures

Do you offer Pentesting and Validation Services?

Yes, we deliver in-depth security assessments to verify the integrity, robustness, and compliance of your PKI implementation. These services can be part of a broader PKI deployment or offered independently for existing environments.

Our scope includes:

Full-stack validation of PKI components including backend systems, service layers, and client interfaces

Targeted penetration testing at the API and protocol level

End-to-end checks for identity, certificate, and key lifecycle flows

Detailed reporting with risk-ranked findings and actionable remediation plans

Do you offer post-deployment support?

Yes, we provide ongoing support to keep your PKI environment secure, up-to-date, and aligned with evolving operational needs.

Our offering includes:

SLA-based technical assistance and expert troubleshooting

Automated tracking of certificate expirations and renewal workflows

Regular patching, infrastructure health checks, and performance monitoring

Flexible support plans that adapt as your ecosystem grows

How does your PKI solution support compliance?

Our solutions are designed to align with ISO 21434, WP.29, and other regulations by offering audit-ready logging, secure provisioning, and cryptographic enforcement policies.
