Defence and security

The challenges facing national security leaders stretch traditional approaches and structures beyond their original purpose. Political and societal tensions, environmental degradation, and regional conflict pose pressing questions. Whilst emergent technologies present risks and opportunities.

Incremental adjustments are not enough to capture new opportunities and address fast-changing threats. The time to break the impasse through bold and rapid change is now.

At PA, we think and work differently, softening traditional boundaries across defence, security, and home affairs. As adversaries seek to exploit the gaps that expose our vulnerabilities, we drive collaboration with our clients to make our defence and security structures stronger.
