Access Controls: Who Can See What, and Why It Matters

The core idea is straightforward: give each person access only to what they specifically need for their role, not broad access by default. A support team member handling billing questions, for instance, doesn't necessarily need visibility into every document a company has ever processed.

This isn't about distrust; it's about limiting the potential damage of any single compromised account, since an account with narrow access can only expose a narrow slice of data even if something goes wrong.

In a small team, informal access, everyone can see everything, often works fine simply because everyone genuinely needs broad visibility. As a team or an organization grows, that same informal approach becomes a real liability, since access that made sense for five people rarely still makes sense for fifty.

Setting up clear roles early, even if a team is currently small, avoids a much harder retrofit later when access has already sprawled.

Periodically reviewing who has access to what, and removing access that's no longer needed, is a simple practice that meaningfully reduces risk over time. Access tends to accumulate as people change roles; it rarely gets cleaned up on its own without a deliberate review.
