The next frontier of Zero Trust is AI.
Private AI isn’t just a deployment model — it’s how we keep control of what we build.
From the EU AI Act to ISO/IEC 42001, the guardrails are here.
The real challenge? Owning your data and your model’s behavior.

AI Security Zero Trust: Comprehensive Protection for Modern AI Architectures
Key Takeaways Zero trust security model provides essential protection against unique AI threats, including adversarial attacks, data poisoning, and model theft that traditional security approaches cannot adequately address. AI architectures with multiple models require granular access controls, continuous monitoring, and microsegmentation to secure data flows between components like training pipelines, inference engines, and model repositories. Organizations implementing zero trust for AI systems report an 83% reduction in security incidents while enabling secure deployment of AI agents and Large Language Models (LLMs) in enterprise environments.

Top Strategies for Implementing Zero Trust Security Today
Zero Trust Security is a cybersecurity concept that means not trusting any entity by default, whether inside or outside your network. It requires every access attempt to be continuously verified. This article explores what Zero Trust Security is, why it’s essential, and the steps to implement it effectively in your organization. U.S. federal agencies are required to adhere to the NIST 800-207 standard for Zero Trust implementation, as mandated by an executive order from the Biden administration.

Zero Trust vs. Secure Access Service Edge (SASE): Who Enables Whom?
Introduction: The Stage is Set In the ever-evolving world of cybersecurity, two concepts dominate discussions: Zero Trust Architecture (ZTA) and Secure Access Service Edge (SASE). A common misunderstanding in the industry is that Zero Trust is part of SASE, but what if it’s the other way around? Instead of considering Zero Trust a subset of SASE, it may be more accurate to say that…

The old castle-and-moat security model is broken. Zero Trust isn’t just a trend—it’s a necessity.

In my latest blog, I break down why "never trust, always verify" is the only way forward and how to implement it without overcomplicating things.
Zero Trust Security: Why It’s a Game-Changer for Cybersecurity
Honestly — conventional security models are no longer holding up. The era of the ‘castle-and-moat’ approach from the security frontline is over. As remote work, cloud apps, and cyber threats become increasingly sophisticated, we need a more intelligent way to protect our data. Zero Trust operates on the premise of "never trust, always verify," meaning it does not assume everything internal to the network is safe.
