We cracked Stuxnet. Now we help companies to build a robust Industrial Internet of Things.

We have been among the first to develop the field of ICS security. We have cracked the Stuxnet malware. We have helped asset owners in critical infrastructure and manufacturing to protect against nation-state level cyber attacks.

Our game-changing OT asset management software helps companies to build secure and reliable OT infrastructures in times of shrinking head counts.

Consider Langner an international software startup with 30 years of experience. We morphed from a leading OT security consultancy to a software vendor, based in the US and in Germany.

Langner is self funded and independent. We don’t depend on external capital and crazy growth expectations. We don’t maintain an expensive workforce of traveling sales people and solution architects (because you don’t need them). We focus on product development with a dedicated team of world class experts that have worked together for more than a decade.

We pick customers who share our vision that OT asset management approaches which don’t include engineering and maintenance are bound to fail. If you share this vision, we’d like to hear from you!

Langner started out as a software company developing PC driver software to connect to industrial automation devices. In the Nineties, when networks became a thing and industrial control systems became networked at a large scale, we were among the first to point out the cyber security risk.

OT security consulting then became our main focus for over twenty years. Our analysis of the Stuxnet malware has triggered global changes in policy and defense. Among others, we were asked for advice by the White House, the Pentagon, the US Senate, and the United Nations.

In our consulting practice we noticed that every single client, no matter how big or small, no matter which industry, lacked an asset inventory which could act as the factual basis for a solid cyber risk assessment.

We finally picked up the challenge to develop OT asset management software that not just revolutionizes OT security, but also gives engineering and maintenance an unprecedented level of visibility of their networks. Today, the OT-BASE OT Asset Management software is our sole focus.
