When you’re evaluating SaaS products, this question should be at the top of your list: “Do you publish a verified Microsoft Entra Enterprise App?”
The answer you get tells you:
- How seriously the vendor takes security
- Whether they expect customers to carry out ongoing identity maintenance
- Whether their integration will survive API changes and updates
- How much operational drag should your team expect
If a vendor offers “Sign in with Microsoft,” there are two ways they might have implemented it. Either they publish a verified Microsoft Entra Enterprise App, or they require every customer to create their own app registration.
These two approaches look similar on the surface, but they create very different outcomes for security teams, admins, MSPs, and long-term maintenance. One scales cleanly. The others create recurring problems that show up months or years later.
This is why the method a vendor chooses should be one of the first questions an IT or security team asks.
The real difference: Convenience vs. Accountability
Some vendors still ask customers to create their own Microsoft Entra app registration. On paper, that sounds flexible. In practice, it shifts identity governance and operational risk straight onto the customer.
It’s not Microsoft that’s introducing friction. The friction appears because the vendor didn’t publish a managed Enterprise App. Without one, customers become responsible for configuring permissions, storing secrets, rotating credentials, and fixing breakages when something changes.
When a vendor does their part and publishes an Enterprise App, the customer experience is simple. Click Sign in with Microsoft, approve the verified publisher consent screen, and you’re done. No digging through Microsoft Entra, no secret management, and no lifecycle surprises involved.
The two approaches
Vendor-Managed Entra Enterprise App
Customer clicks “Sign in with Microsoft”
↓
Microsoft shows vendor-reviewed consent screen
↓
App ownership and security live with the vendor
↓
User is authenticated — no setup required
This gives customers:
- One-click onboarding
- Proper vendor attribution
- Credential rotation handled automatically
- Visibility inside Entra governance and CASB tools
- No secrets or certificates for customers to maintain
Manual App Registration
Vendor tells customer “Create your own app reg”
↓
Customer configures scopes, permissions, URIs, secrets…
↓
App works initially…
↓
Eventually fails due to leaked/expired secret, missing permission, or API upgrade
This leaves customers holding the bag for:
- Config errors
- Permission drift
- Secret rotation
- Breakage during upgrades
- “Who owns this?” confusion later
Where security teams immediately notice the difference
Vendor-managed apps are signed, reviewed, and consistent across every Microsoft tenant. Security teams can approve them once and enforce governance centrally, making investigations cleaner and audits simpler.
DIY app registrations create a unique identity for every tenant. Each app has its own secrets, permissions, and lifecycle. Every security team must evaluate and track it independently. That introduces three major pain points:
- Slower remediation, because every tenant behaves differently
- More investigative noise, with false positives and unusual configurations
- Higher operational load, since every new engineer must learn one-off setups
Vendor-managed apps reduce the surface area. DIY apps multiply it.
| With Vendor-Managed App | With DIY App |
| Verified publisher | No publisher identity |
| App lineage visible | Appears “unknown” |
| Conditional Access applies correctly | Cannot enforce vendor-level policy |
| Governable by Entra security tools | Treated as a local internal app |
| Held to publication controls by Microsoft | No publication oversight |
Lifecycle and operations: Who owns the risk?
| Category | Vendor-Managed App | Manual App Registration |
| Setup | One-click | High chance of mistakes |
| Ownership | Vendor | Customer |
| Secret Rotation | Automatic | Manual and easy to miss |
| API Changes | Transparent to customer | Breaks until reconfigured |
| Audit Trail | Vendor-attributed | “Unknown internal app” |
| MSP Scale | Excellent | Nearly unmanageable |
For MSPs, the cost difference compounds quickly
MSPs feel the pain of DIY app registrations fastest. Every tenant adds:
- A new secret that will eventually expire
- Another approval flow for elevated permissions
- Another opportunity for an unexpected outage
A vendor-managed app removes that overhead entirely. MSPs consent once per tenant and never revisit it.
The bottom line
A vendor-managed Microsoft Entra Enterprise App is not a nice-to-have. It is the baseline for a secure, stable Microsoft integration—vendors who publish show that they understand real-world governance, supportability, and long-term maintenance. Vendors who rely on DIY registrations push that burden onto their customers. If you want predictable security, clean audits, and fewer headaches down the road, choose the product that owns its integration instead of outsourcing the work to you.
The NinjaOne + Intune integration provides IT and MSP teams with what they’ve been missing: true operational control within an identity-first world. It unites governance, automation, and support into a seamless workflow spanning enrollment to retirement.
The result is less friction, fewer blind spots, and a stack that works the way modern IT does.
