About Us

About Us
Security Begins with Identity
PKI Experts stands for specialized consulting around public-key infrastructures in security-critical environments.
We support organizations in building robust and auditable PKI systems – from initial concept to stable operation.
Our focus is on the design and implementation of sustainable PKI architectures and management systems that meet both the highest security requirements and the practical requirements of operation.
We support our customers with certificate and key management, the automation of enrollment and renewal processes, and the integration of PKI into existing IT and security landscapes. Our aim is to develop solutions that are stable, comprehensible and efficiently operable in the long term.
Manufacturer Neutral
We provide advice independently of individual products or manufacturers. Decisions are 100% based on the requirements of our customers.
Pragmatic and Reliable
PKI must work in everyday life: during rollouts, audits, disruptions, and after years of operation. That is what our work is geared towards.
Security by Design
Security requirements are not added later, but planned in a structured manner – starting with the first architectural decision.
Automation as Standard
Manual certificate processes are unreliable. We develop infrastructures with automated life cycles and stable operating processes.

Erfahrung
Our Industry Experience
Over 15 years of project experience in complex and regulated environments:
- Public Authorities and Administration

Arbeitsweise
Our Approach
We don't understand PKI as a product installation, but as a security architecture with organizational responsibility.
That is why we support projects throughout all phases:
1. Identify goals and requirements
We understand your security goals, regulatory requirements and organizational frameworks and translate them into clear, actionable PKI requirements.
2. Designing robust architecture
Based on this, we are developing a scalable, secure and future-proof overall architecture.
3. Define processes and policies
We define clear processes and guidelines that reliably reflect governance, security, and compliance.
4. Implement and integrate technically
We implement PKI with technical precision and integrate it seamlessly into your existing IT landscape.
5. Stabilize operations and make them auditable
We are creating the organizational and technical foundations for a safe, stable and permanently auditable PKI operation.
Das Ergebnis ist eine PKI, die nicht nur funktioniert, sondern langfristig tragfähig ist.

Unser Netzwerk
Our Management
PKI Experts is led by Dr. Marco Schreiber, who has been working in the field of cryptography and IT security for over 15 years. As an experienced PKI architect and technical project manager, he has designed, built, and successfully transformed numerous certificate and smartcard management systems into auditable operational structures.
Our aim is to provide companies with holistic support in building and optimizing their PKI systems – with solutions that are technically sound and work reliably in operation.
For implementation, we rely on a specialized network of experienced experts and partners, which is assembled on a project-specific basis. In this way, we combine the flexibility of specialized consulting with the implementation power of larger organizations – efficient, targeted and without unnecessary complexity.
