Digital Signatures & Seals

Manage Digital Certificates Yourself

Our Trust Center Infrastructure (TCI) allows you to manage digital certificates in a secure and high-performing on-premises server environment.

The basic functions are the legally compliant digital signing and sealing of documents. Furthermore, you have the flexibility to expand the TCI to include PKI and EUDI Wallet functions.

Everything You Need to Know About TCI

eIDAS Certified

Our solution is eIDAS-certified: for Qualified Electronic Signatures (QES) and Seals that are legally binding and recognized throughout Europe.

Flexibly Scalable

While the Trust Center Infrastructure’s basic functions are digital signing and sealing, you can also expand it to include EUDI Wallet, S/MIME, and BYOK features.

High Signature Volumes

You use a high-performance server specifically optimized for high signature volumes. It can be hosted either in your own data center or in our data center.

Highest Level of Security

You manage the certificates in your own server environment – for maximum control and the highest security.

Onboarding Your Employees

Popular Use Case for the TCI

We start by providing you with the required TSP infrastructure – a server equipped with a qualified QSCD. This infrastructure is delivered as a complete package or in separate components, tailored to your specific requirements. This enables you to host certificates (AES, QES) directly at your location and utilize them with your existing signature software.

When a new employee needs a certificate, it is requested via an API. We then identify the employee and provision the correct certificate directly to the QSCD. The employee can then begin digital signing immediately – securely, quickly, and fully on-premises.

The Technology Behind TCI

Applications for PKI-Based Features

S/MIME Email Encryption and Signing

Digital identities for employees and functionaries for secure, GDPR-compliant email communication with automatic signature and encryption.

Device Certificates and Device Authentication

Issuance and management of certificates for end devices such as laptops, printers, and scanners for secure identification and protection of device communication.

Certificate-Based Authentication (e.g., VPN, WLAN, Intranet)

Secure Login without Passwords: Using certificates as strong authentication factors for internal systems, campus Wi-Fi, or remote access.

Bring Your Own Key (BYOK)

You can generate your own cryptographic keys and manage them centrally via the PKI. These keys are subsequently used for encrypting sensitive data - even in cloud environments (e.g., Microsoft 365, AWS, Azure), without control over the key ever leaving your premises.

Securing Servers, Databases, and APIs

TLS/SSL certificates for the encryption and authentication of web services, server-to-server communication, or database access in internal networks.

Certificates for Applications and Specialized Procedures

Securing third-party applications, administration software, or interfaces using machine certificates - also automated via internal PKI policies.
