Zero-trust is redefining cyber security in 2025

Cyber security has long been likened to building a fortress: thick walls, watchtowers, and a moat separating the inside from the outside. This perimeter-focused approach thrived for decades, but in today’s hyper-connected digital world, resources and users extend beyond traditional fortress boundaries, providing attackers with expanded opportunities for engagement. Recent cyber attacks have only underscored the inadequacy of traditional methods, revealing just how vulnerable organisations remain in a dynamic threat landscape.

Zero-trust flips the fortress mindset on its head. It operates under a simple but transformative principle: assume the presences of hostiles actors, always establish and validate identity, and limit access to resources. As cyber threats evolve daily and data sprawls across clouds, applications, and devices, zero-trust has become today a strategic imperative for security and risk management (SRM) leaders.
