TL;DR: As products move from MVP to enterprise use, hard-coded roles, ad hoc access checks, and delayed monitoring become scaling risks that can force expensive re-architecture later, according to Cerbos. The security model has to evolve with the product, or the product team inherits the cost of brittle authorization and trust assumptions.
NHIMG editorial — based on content published by Cerbos: an episode of The Scripting Den on moving from MVP to mature product security
Questions worth separating out
Q: How should product teams handle authorization as an MVP grows into an enterprise product?
A: Product teams should move authorization out of hard-coded application logic before roles, ownership rules, and tenant-specific exceptions multiply.
Q: What breaks when access control is still hard-coded after product-market fit?
A: Hard-coded access control breaks when the product must support more than a simple user-to-action model.
Q: How do you know if your authorization model is too immature for enterprise customers?
A: Your authorization model is too immature if you cannot express ownership, delegation, audit requirements, and tenant separation without adding more if statements.
Practitioner guidance
- Externalise authorization from application code Move access decisions into a policy layer before role logic and ownership checks become tangled in feature code.
- Model enterprise access patterns early Map likely future states such as manager approval, resource ownership, and tenant separation while the product is still small.
- Treat logs and traces as control evidence Capture authorization decisions, critical API calls, and failure events in a way that supports audit, incident review, and customer assurance.
What's in the full article
Cerbos's full episode covers the operational detail this post intentionally leaves for the source:
- The practical trade-offs between hard-coded access checks and external policy enforcement in real products
- Examples of how B2B requirements change authorization design once enterprise customers enter the picture
- Operational guidance on when authentication, audit logging, and monitoring should be treated as part of product architecture
- The discussion of when not to outsource identity controls and when simplicity still makes sense

MVP-era authorization is a temporary assumption, not a control model. The product story here is not that teams should add more checks, but that simple access logic is only defensible while the identity model is still shallow. Once a product begins serving multiple customer types, ownership states, and delegated actions, hard-coded decisions stop being governable. The implication is that authorization must be treated as a living policy layer, not a code shortcut.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- That same research shows only 1.5 out of 10 organisations are highly confident in securing NHIs, which is a governance signal, not just a tooling gap.
A question worth separating out:
Q: Should teams build authentication and authorization themselves or use existing controls?
A: Teams should avoid building common identity controls from scratch unless they are core to the business. Authentication, authorization, and monitoring are undifferentiated infrastructure for most products, so using proven capabilities lets the team spend its time on the logic customers actually buy.
