Some AI decisions don’t age well
AI adoption inside enterprises rarely happens through a single rollout or strategy. It starts with pilots, experiments, and informal usage that gradually becomes part of how work gets done.
That’s not the problem.
The problem is that many of the most important AI governance decisions are made implicitly during this early phase. And once AI usage scales, those decisions become extremely difficult to reverse.
AI governance doesn’t usually fail because organizations chose the wrong approach. It fails because critical choices were made by default, before anyone realized they were being made at all.
Decision 1: What you allow before you fully understand AI usage
Most organizations begin with limited AI pilots or informal allowances: a team using Copilot, developers experimenting with code assistants, marketing testing content tools.
These early permissions feel temporary.
In practice, they set expectations. Once teams build workflows around AI tools, tightening controls later becomes an organizational challenge. What started as experimentation quietly becomes the baseline.
Early boundaries are easier to define and easier to keep. Late boundaries feel like disruption.
Decision 2: Where you draw the AI trust boundary
AI risk no longer lives only at the employee prompt.
AI is embedded inside SaaS platforms, developer tools, and enterprise applications. Data flows into vendor-controlled models and agentic systems that operate without direct user interaction.
At that point, governance becomes about exposure - whether to customers, regulators, or partners - regardless of where the AI runs. Once sensitive or customer data enters third-party AI systems, the trust boundary has already shifted.
That shift is difficult to undo.

Decision 3: Whether governance follows tools or behavior
Early AI governance often starts with tools: which applications are allowed, which are blocked, which versions are approved.
This works briefly. Then AI usage fragments: across embedded features, APIs, copilots, and agents.
When governance is tightly coupled to tools, it struggles to scale. Exceptions multiply, controls become brittle, and risk assessment turns reactive.
Early decisions about governing behavior and usage, rather than individual tools, determine whether AI risk can be managed coherently as adoption grows.
Decision 4: How much risk context you preserve
AI governance is often discussed in terms of visibility. But visibility alone is not the goal.
Security leaders don’t need more activity data. They need to understand exposure: what data is involved, how it is being used, and how that usage aligns with business and regulatory expectations.
Without context, even complete logs become noise. Once AI usage grows without meaningful risk context, organizations lose the ability to assess exposure in a way that supports decisions, audits, or explanations.
That loss is permanent.
Decision 5: Who leads AI governance when ownership is unclear
AI governance sits at the intersection of security, IT, legal, GRC, and the business. In many organizations, that ambiguity slows progress.
But ambiguity doesn’t stop decisions from being made. It just means they’re made without clear ownership.
In practice, security leaders are already being asked to explain AI risk, provide assurance, and define guardrails. Even when no formal mandate exists.
AI governance will have a leader. The question is whether that leadership is intentional or incidental.
A leadership opportunity for the CISO
This moment is different from past technology shifts.
With cloud and SaaS, security was often brought in after adoption was already underway. With AI, CISOs are involved early. They’re asked to frame risk, guide adoption, and align stakeholders.
This isn’t about centralizing control. It’s about leading alignment: helping the organization adopt AI in a way that is responsible, explainable, and sustainable.
Handled well, AI governance becomes less about restriction and more about enabling confidence across the business.
Why these decisions only happen once
These decisions are different because of when they are made.
They happen early, often quietly, and without formal checkpoints. Once AI usage is embedded in workflows, contracts, and expectations, revisiting those choices becomes exponentially harder.
Delaying AI governance doesn’t preserve flexibility. It reduces it.
In AI governance, “we’ll decide later” often means the decision has already been made - just not deliberately.
What acting now actually means
Acting early on AI governance doesn’t require predicting every future use case or locking systems down. It means being intentional while AI usage is still forming.
That starts with understanding risk exposure, not just monitoring activity:
- Which types of data are already being introduced into AI-driven workflows, intentionally or not?
- Where is AI influencing decisions or actions in ways that may conflict with regulatory requirements or internal policy?
- In which scenarios would you struggle to explain how AI was used, or on what basis, if asked by a customer, auditor, or executive?
- Which early guardrails help define acceptable AI usage without slowing adoption?
The most costly AI governance failures aren’t caused by bad judgment.
They’re caused by decisions made implicitly, when there was still time to choose.
Closing thought
For a broader perspective on how AI is entering the enterprise, particularly through employees and everyday workflows, Omri Iluz, co-founder and CEO of Lumia, recently shared his view on how organizations are navigating this shift and what it means for governance moving forward.
