TL;DR: Rolling your own authorization is getting harder to justify as systems grow more complex, regulated, and latency-sensitive, according to Cerbos. For most teams, the real question is whether custom access logic is a competitive advantage or an expensive source of risk, technical debt, and slow delivery.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “Building your own authorization solution vs. buying an off-the-shelf one”.
Key questions
Q: What should teams do if they do not want to build authorization in-house?
A: They should adopt a solution that separates policy from application code and keeps identity and access behaviour maintainable as requirements change.
Q: Why does custom authorization become riskier as applications scale?
A: Custom authorization becomes riskier because every new role, tenant, rule, and workflow adds policy surface that must be tested and maintained.
A: A tightly coupled model usually shows up when small policy changes require code changes, deployments, or manual edits across multiple services.
Practitioner guidance
- Define whether authorization is a competitive advantage Map which access decisions are core to product differentiation and which are standard governance controls that do not justify custom build effort.
- Quantify the hidden cost of in-house auth Include developer time, testing, redeployments, infrastructure support, and future maintenance when comparing build and buy options.
- Test policy expressiveness before committing Run a proof of concept to see whether your required roles, attributes, and future changes can be modeled cleanly in policy.
Bottom line: Authorization is harder to keep in-house when access rules become complex, regulated, and tightly coupled to the application.

Authorization is a governance control, not just an application feature. Once access logic determines who can read, change, or delegate sensitive actions, it becomes part of the identity control plane. That means design choices around ownership, policy expression, and lifecycle management have direct security and compliance impact. Teams that treat authorization as incidental code usually discover too late that they have built an ungoverned control surface.
A question worth separating out:
Q: How should regulated organisations choose between build and buy for authorization?
A: Regulated organisations should choose based on how well each option supports visibility, auditability, and controlled change. If the business needs strong assurance but cannot afford long development timelines or ongoing policy maintenance, buying is usually easier to defend than maintaining a bespoke control layer.
