It’s easy to paste data into an LLM “just to test something.” Whether it’s a report, a dataset, or a few real customer records, the goal is usually speed—not risk. But in regulated industries like finance, even small, unintentional data leaks can have serious compliance, security, and trust consequences.
Public LLMs weren’t designed with financial regulations or sensitive data controls in mind. Once information is shared, teams often lose visibility into where that data goes, how long it’s retained, or who might access it. Over time, this kind of casual usage can quietly bypass internal policies without anyone noticing.
Do you think teams are underestimating the risks of public LLM usage? And where should organizations realistically draw the line between convenience, productivity, and data security?

Rom - From a security and compliance point of view, I would find it very risky to put any real customer data into a public AI tool. It does bypass most internal policies. In my opinion Public AI tools should only be used for testing or proof of concepts without ever using any real customer data. Mickey Mouse and Donald Duck are two of my favorite test profiles. Do you agree with this approach?

I absolutely agree with your approach! Using synthetic identities like Mickey Mouse and Donald Duck is the perfect way to explore a tool's capabilities without compromising real-world security. The danger of "just testing" with real data is that it creates a false sense of security; once that information is logged or cached by a public model, you’ve effectively lost data sovereignty. For finance teams, the line has to be firm: Public Tools: Strictly for non-sensitive brainstorming or testing with fictional profiles. Private Environments: Reserved for actual financial data where you have guaranteed isolation and zero training on your inputs. Education is the real game-changer here—when teams understand the "why" behind the rules, they are much more likely to stick to the "test profiles".
I think many teams underestimate the risk because public LLMs feel fast and harmless to use. In regulated environments, even small data exposure can create serious compliance and trust issues.
I believe the line should be clear: no non-public, sensitive, or regulated data in public AI tools. Productivity matters, but without governance and approved platforms, convenience quickly turns into risk.

You’ve hit the nail on the head regarding the "convenience trap". Because these tools are so frictionless, they can quietly bypass internal policies and governance frameworks without anyone noticing until a breach or audit occurs. In regulated industries, speed and convenience simply aren't worth the trade-off of reputational damage or legal consequences. We have to shift the mindset from "cleaning up" after using AI to designing a "trusted pipeline" from the start. Productivity shouldn't be a gamble; it should be a result of using approved, secure platforms that provide audit-friendly logs and transparent data transformations.

This is a fair concern, and I think the risk is less about bad intent and more about design drift.
Most teams are not “leaking data” deliberately. They are optimising for speed inside systems that were never architected for AI-mediated work. When AI becomes frictionless, policy enforcement that relies on individual judgment quietly erodes.
Two distinctions help bring clarity.
First, sensitivity is contextual, not binary. Teams often treat data as either “confidential” or “safe,” but risk actually emerges from combinations. Partial datasets, internal assumptions, anonymised records that can be re-identified when combined. These often slip through because they do not feel sensitive in isolation.
Second, the real failure is governance lag. Public LLM use accelerates faster than most organisations update decision rights, thresholds and accountability. Without explicit rules on what can be shared, by whom, and under what conditions, people will default to convenience. Not because they are careless, but because the system silently rewards it.
Where to draw the line. I would not frame it as banning public LLMs. That usually drives usage underground. A more realistic line is this.
Public tools for non-sensitive reasoning, drafting and learning. Controlled environments for anything involving real data, even samples. Clear decision thresholds that trigger escalation, not blanket approvals.
In short, this is not primarily a technology problem. It is a governance and work-design problem. If organisations do not redesign how decisions about AI use are made, they will normalise risk long before they notice it. Saving Changes...

Some individuals follow the same approach they use with Google and choose not to log in. By doing so, and if I am not mistaken, Google cannot directly link the collected data to a specific user for the purpose of offering personalized products or services.
The same principle applies to ChatGPT and other large language models. Not logging in and avoiding the sharing of confidential information (such as names or specific references) can help reduce personalization and limit the extent to which data is associated with an individual, even though it does not guarantee complete anonymity!
