PKI & Certificate Management
Digital certificates are a key component of modern IT security. They protect communication, enable secure authentication, and form the basis of many security-critical systems.
However, in many organizations, certificate landscapes grow unchecked for years. A lack of oversight, expiring certificates, or insecure PKI structures can lead to security risks or even system failures.
We support companies in building, securing and structuring their public key infrastructure as well as in the secure lifecycle management of certificates.
Typical problems in certificate management
Digital certificates are now used in almost all areas of IT – from web servers to internal systems to machine identities.
However, many environments lack a central overview of issued certificates and their expiration dates. Certificates expire unexpectedly, are issued without oversight, or remain active after system shutdowns.
Unclear PKI structures, insecure root certificates, or missing processes for managing certificates can also pose significant security risks.
A structured certificate management system creates transparency, reduces operational risks and ensures that cryptographic infrastructure can be operated reliably and transparently.
Our services in the area of PKI and certificate management
We support organizations in building and securely managing their cryptographic infrastructure.
Our services include, among other things:
• Analysis of existing PKI architectures
• Building or optimizing internal public key infrastructures
• Introduction of structured processes for certificate management
• Securing root and intermediate certification authorities
• Implementation of Certificate Lifecycle Management
• Integration of certificates into existing infrastructure and security architectures
The goal is a stable and long-term maintainable PKI structure that reliably meets both security and operational requirements.
Cryptographic protection mechanisms and secure authentication are central components of modern cybersecurity requirements.
A structured PKI and controlled certificate management support, among other things, requirements from:
• NIS2 – Protection of communication and access controls
• DORA – secure authentication and protection of critical systems
• BSI C5 – Cryptography and Key Management Controls
• Telecommunications Act (§166) – technical security measures
A well-structured PKI allows cryptographic security mechanisms to be operated reliably and transparently.
