What is the PwC Defense & Security Institute?

In an era defined by converging threats – from geopolitical volatility and hybrid warfare to cyber aggression and fragile supply chains – organizations face a transformation imperative unlike any before. The PwC Defense & Security Institute (DSI) was founded to meet this moment. We foster strategic partnerships across government, industry, and academia to connect our clients with the expertise and networks that matter most. We generate thought leadership and strategic insight that sharpens decision-making and gives our clients an informational edge. And we harness PwC's global multidisciplinary capabilities – spanning technology, risk, transformation, and advisory – to translate foresight into practical, implementable solutions. The Institute is where strategic perspective meets consulting excellence: a platform that helps our clients not only understand the shifting security landscape, but act on it decisively.

“The geopolitical tectonic plates are shifting – and Europe is right in the middle of it. Trade, technology and finance have become strategic instruments, and defense spending alone no longer generates a stimulus for growth. That is precisely why we founded the PwC Defense & Security Institute: a place where consulting excellence is combined with academic profundity and an international network of partners. After all, security today is a task for society as a whole – and we want to use our global expertise to make a concrete contribution to ensuring that Europe remains capable of taking action.”

Powerful network

No single organization can address today's complex security challenges alone – it takes varied expertise, diverse perspectives, and shared purpose. The PwC Defense & Security Institute is proud to partner with renowned organizations across the spectrum: from leading media houses and established think tanks to academic institutions and industry pioneers. Together with our partners, we combine complementary strengths to generate deeper insight, amplify our collective voice, and drive meaningful change. These collaborations are not peripheral to our mission – they are essential to it.
