Azure AD and SSO was seamlessly integrated and allowed for easy integration with all my other tools. By adopting this out of the gate, I also did not need any AD servers, which is beautiful. Who wants to maintain servers anymore? Also, by purchasing this one plan, I was able to remove the need for any SSO vendors like Okta or Ping. The authenticator app also made MFA easy, simple, and safe, and we're fast approaching a passwordless login. Couple that with all the MDM and AV capabilities and it's hard to choose another solution. Especially if you're greenfield.
