Langner is a leading cyber security consultancy specialized in protecting facilities where more is at risk than just information — life and limb, environmental safety, or national security. Our core expertise is the protection of high-value assets in critical national infrastructure, defense, and large-scale manufacturing against sophisticated cyber attacks by criminals, hacktivists, terrorists, and nation states. Established in 1988, we have decades of hands-on experience within the most complex and most critical installations, such as nuclear power plants. Our prime focus is on cyber-physical systems such as production and safety controllers where cyber compromise has immediate physical effects. Our capabilities were demonstrated by our globally recognized swift cracking of the first cyber weapon in history – the Stuxnet malware.
Our clients typically don’t ask for awareness-raising missions but for reliable and practical measures to achieve substantial protection against directed cyber attacks. Rather than diffusing clients with fear, uncertainty, and doubt, we present comprehensive, verifiable technical vulnerability analysis that has been judged by independent subject matter experts as exceeding those of national laboratories. We identify design basis vulnerabilities that sophisticated adversaries would attempt to exploit, and suggest mitigation that fits the client’s corporate culture and budget.
