Melchior Limacher is an IT security consultant and penetration tester. Since 2015, he has been conducting technical security audits, architecture reviews, and risk analyses through his company, Limacher Informationssicherheit GmbH—ranging from web and mobile applications to Active Directory, embedded devices, and OT and IACS environments. As a physicist (MSc ETH Zurich), he combines systematic thinking with offensive security. He has helped design security architectures for Industrial IoT, automotive portals, and smart home systems; supported ISO 27001 ISMS projects; and trained developers, administrators, and business owners—including through a lecture at the University of Zurich.
Certified as an OSCE, OSCP, CISSP, ISSAP, and ISO 27001/27002 manager, among other credentials, he prepares participants at Digicomp for OffSec certifications through hands-on training. The focus is on OSCP and OSAI: methodology, enumeration, exploitation, and the perseverance these exams require—not rote knowledge, but reproducible skills.
