Ralph Langner is the founder, director, and lead OT-BASE architect, at Langner, an independent cyber-security consulting firm that specializes in control systems -- electronic devices that monitor and regulate other devices, such as manufacturing equipment.

These devices' deep connection to the infrastructure that runs our cities and countries has made them, increasingly, the targets of an emerging, highly sophisticated type of cyber-warfare.

Since 2010, when the Stuxnet computer worm first reared its head, Langner has stood squarely in the middle of the battlefield. As part of a global effort to decode the mysterious program, Langner and his team analyzed Stuxnet's data structures and revealed what he believes to be its ultimate intent: to control system software known to run centrifuges in nuclear facilities -- specifically, facilities in Iran. Further analysis by Langner uncovered Stuxnet's clandestine origins, which he revealed in his TED2011 talk.

Since its founding in 1988, Langner has accumulated more than 25 years of hands-on field experience in the cybersecurity issues of power plants, water treatment facilities, food and beverage plants, nuclear facilities, automotive factories, steel mills, and much more.
