Our Story

SIGNL4, Derdack’s SaaS solution, re-invents critical alerting, incident response and service dispatching for operating critical infrastructure. It addresses the needs of people working in areas where swift response matters. SIGNL4 is designed to automate and optimize incident response and management processes and has strong emphasis on mobility. Unlike traditional IT applications, it incorporates concepts of consumer products for greater productivity, usability and more fun at work.

Founded in 1999, Derdack is a long-term innovator in alert management and incident response. We are based in Berlin, Germany, Richmond, Virginia and Bern, Switzerland. Our global customer list spans over 50 countries and includes BASF, Daimler, BMW, Porsche and many other leading brands. Derdack is a privately owned company with steady organic growth.

Why is it called SIGNL4?

“Our customers and users keep the most-critical services and systems up and running – 24/7. Our goal is to empower them to live up to the challenge and to even reach new heights in productivity, responsiveness, reliability – and work-live balance.”
