- Microsoft Entra ID
Best for: Companies running Microsoft 365
Entra ID earns its place because it is often already your identity provider, so the question is how far to extend it rather than whether to buy it. It fits companies of any size on Microsoft 365. Map what your current license includes against what you need, such as privileged identity management, before you add a second identity product.

- Okta Single Sign-On
Best for: Teams with mixed apps that want a vendor-neutral sign-in layer
It is on this list as the neutral choice, because it connects to your apps without tying your identity to one platform vendor. It fits companies of any size that run a mix of Microsoft, Google and many SaaS apps. If Microsoft already runs most of your estate, weigh whether a separate sign-in layer is worth running next to it.
