IronNet believes that Collective Defence – where entities from the private and public sectors work together to protect against highly sophisticated attackers – is the best line of defence.

Collective Defense represents a radically different approach to cybersecurity by breaking down the silos that historically have provided individual entities with only a narrow view of the threat landscape. This limited visibility makes it very difficult, nearly impossible, to understand the offensive strategy at play or to map out the best defensive plan to stop the bad actors and mitigate threats quickly.

Founded by General (Ret.) Keith Alexander, former Director of the U.S. National Security Agency and Commander of U.S. Cyber Command, IronNet brings together a team of highly experienced strategic, operational and technical cybersecurity experts to develop and deliver outstanding cybersecurity products and services. IronNet’s goal is to "continue the mission" that General Alexander led for the U.S. for many years: securing nations and critical industry sectors in cyberspace through Collective Defense.

Using complex behavioural modeling, big-data analytics and advanced computing capabilities, IronNet provides best-in-class cyber defense based on advanced threat detection and machine-time knowledge sharing. The result is unprecedented network visibility; early threat awareness; and targeted, business-informed mitigation actions. IronNet offers a Collective Defense solution through anonymized sharing and correlating cyber threat and event data across multiple organisations to provide sector-wide and nation-wide real-time threat visibility.
