Agentic AI is moving fast and most teams lack visibility into what’s actually happening.

Meet our sponsor for this weeks newsletter: @harmonicsec !

In a 2025 study of employee generative AI use, 21% used ChatGPT in free, personal accounts, where data becomes part of LLM training data. And 7% of employees used Chinese generative AI tools at work. (Study by @harmonicsec of their users)

The problem is that an AI ban won't create security.
Bans create invisibility.

If you see shadow AI as a design constraint and worked to turn it into something visible, measurable, and well-governed, instead of trying to suppress it with blanket bans, we want to hear from you.

@SANSInstitute AI Summit 2026 has a full track on AI Governance & Risk.

We want enterprise AI inventory methodologies with actual numbers. Framework implementations with measurable outcomes. EU AI Act compliance stories--what broke, what worked. Cross-functional governance models that survived contact with reality.

The CFP is open until Friday, January 16 at 5pm ET.

🎙️I recently sat down with @patersonae, CEO of @harmonicsec . We discussed how their Zero-Touch Data Protection tackles AI data security, the risks of shadow AI, and how their browser-based solution helps enterprises adopt AI safely. Worth a listen!

It's hard to believe it's already been a year since ChatGPT was released. In my latest @harmonicsec blog, I take a look beyond ChatGPT - "How 10,000+ AI tools have changed the workplace and redefined data security".
