Data protection in the first place
Highest safety standards

Regular backups
We automatically back up your data every day in several German data centers. Even in the event of a total failure, we can restore your data within a very short period of time so that operations can continue seamlessly.
Disaster recovery
Our data centers offer automated, encrypted and redundant data backup with variable backup intervals. This is complemented by a comprehensive disaster recovery concept that ensures the continuous availability and integrity of your data. In the event of an outage, your data can be recovered within a very short time.
GDPR & data protection
ZEP and ZEP GmbH are fully GDPR-compliant and guarantee maximum data security. This includes an AVV (order processing contract), our own ISO/IEC 27001 certification and the use of certified high-security data centers. Encrypted data backups and a disaster recovery concept enable rapid recovery and continuous backups.
Secure by Design
We rely on a holistic security concept: With single sign-on (SSO), 2-factor authentication (2FA/MFA), configurable password policies and role-based access control (RBAC), you effectively protect your data from unauthorized access. In this way, you always have full control over who can access which information and data sets.
