Trust center for highly secure infrastructure:
- Provision of certificates for maximum security
- Long-term, expensive certificates
- Highest security standards
- Very complex interfaces and technologies
Regulatory requirements:
- Qualified electronic signature (QES) process
- Sealing process

- Identification process
- Other relevant processes
The result is two worlds that are difficult to reconcile –
either customers have to choose one of the two, or they face expensive,
complex and error-prone integration projects.
SecCommerce and D-Trust have been active in the PKI market for over 27 years and jointly develop a solution perfectly tailored to the needs of their customers.
By using Trust Services, you secure critical steps in digital transformation processes with the highest level of security. The focus is not only on protection – security is deliberately deployed to best support customers without compromising user-friendliness.
