Within the scope of a penetration test based on the “Open Source Security Testing Methodology Manual” (OSSTMM) and the guideline for conducting penetration tests by the Federal Office for Information Security, the EYEVIDO Cloud Software was tested by independent security experts of TÜV SÜD. In addition, tests were conducted according to the “OWASP Testing Guide”, the Open Web Application Security Project. Together with TÜV SÜD experts, effective protection mechanisms for optimum data security have been implemented in several iterations. Our data security is at the highest level and thus meets the requirements of a sole proprietorship up to the demands of a large corporation. For interested parties with particularly restrictive data security guidelines, we offer the possibility of inspecting the TÜV SÜD Sec-IT final report in the interest of a maximum transparent risk assessment.
