ANECDOTE

2007 Cyberattack Shaped National Resilience

Estonia learned hard lessons from the 2007 large-scale state-backed cyberattack that targeted government IT infrastructure.
Kalev Koidumäe says Estonia's systems stayed operational and that those defenses still work well today.

INSIGHT

Space Is Integral To Modern Defence

Estonia's space sector is software-centred with ~100 companies focusing on cameras, materials and satellite services for export.
Kalev argues space is now an organic part of defence planning and battlefield operations rely heavily on satellite data.

ADVICE

Teach Cyber Hygiene And Test Regularly

Teach cyber hygiene early and run regular exercises to keep society and institutions prepared.
Kalev notes schools, businesses and reserve forces all practice cyber tests annually to build awareness.

What role does cybersecurity play when the battlefield extends beyond Earth's atmosphere? In this special episode recorded live in Tallinn for the fifth anniversary of the Software Defined Space Conference, I sit down with Kalev Koidumäe, CEO of the Estonian Defence and Aerospace Industry Association, to explore how software and security are transforming the future of space and defense.

Kalev shares how Estonia, a nation of just 1.3 million people, has built global credibility through innovation, collaboration, and cyber resilience. From the lessons of the 2007 state-level cyberattack to the country's integration of space technologies within NATO's defense framework, Estonia has developed a model that combines agility with strategic foresight.

Our conversation spans everything from the evolution of Estonia's space sector to its growing ecosystem of AI-driven defense technologies, autonomous systems, and satellite solutions. Kalev also explains how lessons from the war in Ukraine are reshaping Europe's defense landscape and accelerating the need for resilient, software-defined systems.

What makes this discussion particularly fascinating is the balance Estonia maintains between national sovereignty and international cooperation. Kalev explains how the country's reserve army model, cyber education initiatives, and public-private partnerships have created an ecosystem where innovation is both strategic and deeply rooted in civic responsibility. It's a blueprint for how smaller nations can play a meaningful role in global security through ingenuity and collaboration.

As the world navigates an era of heightened geopolitical tension and rapid technological advancement, this discussion offers a glimpse into how small nations can make a big impact in securing both cyberspace and outer space.

So what can larger nations learn from Estonia's approach to innovation, readiness, and cyber defense? And how might software continue to redefine the future of space security? Share your thoughts after listening.
