Quality Standards
With high expectations of ourselves, we ensure the quality of our work and, in turn, the future of our customers and our team. In addition to fostering a collaborative atmosphere in our relationships with customers, we place great importance on maintaining a positive environment within the company. After all, the quality of our output is closely linked to the quality of our workplace.
Certifications
MTG develops and distributes innovative IT security software solutions with high demands on confidentiality, integrity, and availability. The fulfillment of these security objectives in information security is our self-evident quality claim.
Since March 2017, the entire company has been certified according to ISO/IEC 27001, and since July 2025, we have been certified according to DIN EN ISO 9001:2015.
MTG software always complies with cryptographic and operational requirements from NIST and BSI. These are actively monitored and regularly updated. MTG development guidelines include reviews and checks for secure coding constructs. This includes the consideration of OWASP guidelines. The developers are supported by automated code analysis. Penetration tests are part of our release process.
We are already developing solutions in the field of post-quantum cryptography (PQC) to protect our customers' ERS® systems against future threats from quantum computers. An important aspect for the successful integration of new PQC algorithms is the use of hybrid methods. Hybrid methods combine the advantages from both worlds: On the one hand, the robustness of crypto methods that have been proven millions of times and are in use (e.g., RSA, ECC) and, on the other hand, the combined use of the new, post-quantum secure methods.

An excellent team of leading IT security experts contributes to the success of our customers and creates the basis for long-term relationships.
