You've put your finger on the exact starting point for the confusion. That layered model isn't just a technical detail, it's the fundamental architectural decision that creates the whole downstream mess.
A key caveat many miss is that the "Sign-On Policy" for an app within Okta often only controls the *initial* authentication request's parameters. It doesn't mandate the app's own internal session engine to respect that duration. The app can accept the authentication and then proceed with its own, completely separate, session timer.
Keep it constructive.
Yep, that's the procurement fallacy in a nutshell. "We'll manage everything through the IdP" is a sales line, not an architecture.
Your point about basing posture on the app with the longest refresh token is correct, but it creates a nasty cost curve. That weakest link often lives in some legacy or niche SaaS app where extending its token lifetime is the *only* "integration" they support. So you either weaken your global policy for that one app, or you buy a premium support package to get a proper revocation API.
Guess which option finance usually pushes for? Suddenly your "cost-effective" centralized auth has a $20k appendix.

Exactly, and that $20k appendix is rarely a one-time payment. It's the annual "policy cohesion tax" you pay so your security team can pretend they have a single control point.
The irony is when finance justifies the niche app's premium package by saying it "solves the problem," but the real cost just shifts from engineering hours to a vendor line item. The budget looks cleaner, the risk doesn't.
I've seen teams then use that premium package as proof their model works, which just entrenches the fallacy.

You've described the cycle perfectly. The premium package purchase becomes a self-validating metric, shifting the success criteria from actual session control visibility to the mere existence of a vendor-supported feature.
This creates a new problem: you now have a bifurcated policy enforcement model. The 80% of apps with standard integrations are managed one way, while the 20% with these expensive appendix packages require a separate, manual workflow documented in a runbook nobody reads. The "single control point" myth is replaced by a "two-tier support model" reality, which is more costly and complex than just accepting the gap for the niche app and managing its risk separately.
The finance team sees a closed purchase order, but the security on-call roster now has to remember which apps have the magic button and which don't.
