Zero Trust Architecture in 2025 — What Works and What’s Hard
In 2025, the term “Zero Trust” no longer merely refers to a trend; it has become the cornerstone of contemporary cybersecurity. Yet, the ideal of “never trust, always verify” is very widespread in the papers of companies, but making it work in practice is still very difficult.
Organizations are having a hard time applying true identity-based access controls because of hybrid work, the cloud, and AI networks. The majority of groups still use traditional perimeter models, and when third-party apps or IoT devices are involved, Zero Trust is even more difficult to implement.
Cybercriminals, too, are modifying their strategies — they are making use of AI and automated systems to pose as trusted users and catch the verification process.
