Our Story

Nous sommes une équipe basée à Berlin (anciennement connue sous le nom de Company Shield) unie par une mission : protéger les individus, car ils restent le maillon le plus faible de la cybersécurité. Alors que les attaquants utilisent l’IA pour exploiter les vulnérabilités, un nombre croissant d’entreprises deviennent les victimes de cyberattaques impitoyables.

C’est pourquoi nous sommes déterminés à créer 10 millions de pare-feux humains d’ici 2028 !

Notre aventure a commencé lorsque nos trois fondateurs se sont rencontrés chez le decacorn allemand Celonis. Confrontés directement aux menaces croissantes pesant sur les clients - et à l’inefficacité des formations de cybersécurité traditionnelles - ils ont compris la nécessité d’une nouvelle approche de la sécurité humaine.
