Proposal: Microsoft 365 Business Premium Upgrade

Cascades Tucson — Shared Phone Deployment & Security Upgrade

Prepared by: Howard Enos, MSP Date: April 14, 2026 Revision needed (flagged 2026-04-18): this proposal sizes Premium at 23 users, but the caregiver roster (docs/cloud/caregiver-m365-p2-rollout.md) lists 39 caregivers / MedTechs / CCGs with no current M365 identity who actually USE the 25 shared phones. Without their accounts + Conditional Access, the phones don't deliver per-person HIPAA auditability. Updated target is closer to **61 Premium licenses ($1,342/mo)**, not 23 (~$506/mo). The "saves $56.50/mo" narrative below is true of the staff-only cleanup but must be re-framed as "licensing the people who will use the phones is new spend driven by HIPAA compliance, not a cost-saving move." Leave this document as the starting point; re-present to Meredith with the updated math before purchasing.

The Problem

Cascades is deploying 25 shared phones so employees can access ALIS (medical records) and email without relying on shared computers. This improves HIPAA compliance by giving each employee their own login.

However, the current Microsoft 365 plan creates several challenges:

1. Every time an employee picks up a phone, they must manually log into ALIS, Outlook, and other apps — each with separate MFA prompts
2. No way to automatically clear data when one employee hands a phone to another — risk of PHI exposure
3. No way to skip MFA on trusted devices — employees get frustrated, find workarounds, or share logins (HIPAA violation)
4. No centralized phone management — no remote wipe, no app enforcement, no compliance monitoring

The Solution: Microsoft 365 Business Premium

Upgrading from Business Standard to Business Premium unlocks:

1. Shared Phone Mode (Microsoft Intune)

• Employee picks up any phone and taps Sign In
• Enters their username and password (same as their PC login)
• ALIS, Outlook, and Edge auto-sign-in — no separate logins needed
• When done, employee taps Sign Out — phone wipes all data automatically
• Next employee gets a clean phone. User switch takes ~30 seconds.

2. Skip MFA on Company Devices (Conditional Access)

• Managed phones on the Cascades network are automatically trusted
• No MFA prompts for employees using company phones at work
• MFA still required if someone tries to log in from an unknown device or location
• ALIS uses Microsoft Entra as its identity provider — one sign-in covers everything

3. Full HIPAA Audit Trail

• Every sign-in logged: who, which device, when, where
• Compliance dashboard shows which devices meet security requirements
• Automatic alerts for non-compliant devices

4. Additional Security (included at no extra cost)

§164.312(d) — Person Authentication	Basic MFA, employees share logins to avoid it	SSO + Conditional Access — easy to use, hard to bypass
§164.312(b) — Audit Controls	Minimal logging	Full sign-in logs: who, when, which device, what was accessed
§164.310(d)(1) — Device and Media Controls	No phone management	Remote wipe, encryption enforcement, compliance monitoring
§164.312(e)(1) — Transmission Security	No DLP	DLP prevents PHI from leaving the organization via email
§164.312(a)(2)(iv) — Encryption	Not enforced on phones	Intune enforces device encryption on all managed phones

Recommendation

Upgrade to Microsoft 365 Business Premium. It solves the shared phone problem, simplifies employee experience, strengthens HIPAA compliance, and actually saves money after the planned shared mailbox cleanup.

The alternative — keeping Business Standard with a separate MDM product — costs more in admin time, provides a worse employee experience, and leaves security gaps that Business Premium closes out of the box.
