15 Years of Zero Trust: Why It Matters More Than Ever

Fifteen Years of Zero Trust: Why It Matters More Than Ever argues that zero trust remains essential as attacks evolve with AI, quantum computing, and billions of hyper-connected devices. The piece traces the model back to John Kindervag’s early work at Forrester and notes how the 2015 OPM breach, where more than 21 million people’s data including fingerprints were exposed, highlighted the limits of perimeter-based security.

It also explains how a 2016 report and subsequent federal policy moves led to the adoption of zero trust across government, culminating in a 2021 presidential executive order. The author stresses that zero trust is not a product but a mindset and a continuous transformation, emphasising segmentation, policy, inside‑out design, and ongoing visibility.

In the Automation and AI section, the argument is made that breach containment must operate at machine speed and that AI can both empower attackers and strengthen defenders if enforceable policies are applied at scale, according to John Kindervag.
