The upcoming CISODAY on May 21st is dedicated to one defining theme:

Ecosystem Resilience

The notion of ecosystems is not new in IT. Traditionally, it stood for a collection of interconnected technologies – often grown organically, rarely designed for resilience, and typically viewed through a narrow IT lens. In these environments, cybersecurity was treated as a technical discipline, reactive by nature, and largely disconnected from the way organizations operate. The role of the CISO in this operating model was inevitably limited.

This model has reached its end.

Today’s threat landscape is dynamic, asymmetric, and deeply interconnected. Threats do not respect organizational boundaries, architectures, or ownership models. No single team, tool, or individual can maintain oversight alone. Cybersecurity is no longer about defending systems in isolation; it is about understanding, anticipating, and managing threats as they evolve across an entire ecosystem.

Real resilience emerges only when cyber threat management is embedded throughout the organization. This requires an ecosystem in which people, processes, and technology are deliberately aligned around a shared understanding of the threat landscape. Networks, devices, applications, identities, partners, and data must function as one coherent system – continuously informed by cyber threat intelligence (CTI), capable of detecting weak signals, correlating anomalies, and responding in a coordinated and timely manner.

Perimeter-centric thinking has become insufficient. Modern resilience is built on situational awareness, contextual intelligence, and the ability to adapt defenses as threats change. CTI is not an isolated function; it is the connective tissue that enables informed decision-making across technical, operational, and strategic levels.

In this ecosystem-driven approach, the CISO plays a different role. It has moved from ownership to orchestration. Cybersecurity is a shared responsibility, distributed across leadership, specialists, and operational teams, each contributing from their own vantage point. Resilience is no longer delivered by controls alone, but by collective understanding and coordinated action.

While this approach is increasingly recognized, it is still practiced by only a minority of organizations. Many remain fragmented, reactive, and structurally unprepared for the realities of today’s threat environment. This is precisely where the CISO Community plays a role: supporting organizations in moving from isolated defenses to resilient cyber ecosystems.

The community itself is an ecosystem: connecting organizations, sharing threat insights, exchanging experience, and strengthening collective resilience.

CISODAY brings this to life. 

Join us on May 21! Because in an interconnected threat landscape, ecosystem resilience is not something a CISO can build alone.
