We help our customers build, operate, and maintain robust OT infrastructures
We combine experience from consulting critical infrastructure operators, and cutting-edge technology into practical and scalable real-world solutions. We’re committed to make mission-critical cyber-physical infrastructure more reliable, secure, and robust.
That’s what we do for three decades
Who we are
Langner is a hybrid software and consulting firm specialized in cyber security for critical infrastructure, large-scale manufacturing, and defense. We did not just produce printed paper or fancy technical gizmos but results that changed the way cyber security, and national security in a larger sense, is seen.
Our analysis of the Stuxnet malware has triggered global changes in policy and defense. In cyber-physical security, we know what works and what doesn’t by decades of hands-on experience. We have given advice to the White House, the Pentagon, the US Senate, the United Nations, and many others.
We believe that cyber-physical security requires more than just technical point solutions — namely strategy and policy, and the indispensable knowledge of human experts, empowered by strong analytical tools. We believe that a combination of strategic thinking, sound technology, good data and skilled people can and will solve the most pressing cyber-physical security problems, and meet the challenge of building a reliable and safe Industrial Internet of Things.
