Michael Behringer is a founder and seasoned network security expert with over two decades of experience designing and protecting critical infrastructure, including a 19-year tenure at Cisco where he rose to Distinguished Engineer focused on autonomic networking and core network security. He combines deep technical pedigree—MSc in Computer Science from TUM, published RFCs, papers, patents and a book on MPLS VPN security—with hands-on delivery of pan‑European network designs from his earlier role at DANTE. Now leading Key12, he crafts bespoke training and consulting on network complexity, industrial and operational security, and DoS mitigation for high-stakes environments. An active IETF participant, he brings both research-level insight and practical operational experience, making him equally at home shaping protocols and hardening live networks. An interesting non-obvious detail: he pivoted from large-vendor R&D back to boutique, high-touch consulting to focus on the craft he enjoys most—teaching and bespoke security engineering.
