(And Why Business Premium Has Already Become the New Baseline Plan)
Many business owners assume Multi Factor Authentication (MFA) fully protects their Microsoft 365 accounts.
Today, that is no longer true.
Most Microsoft 365 breaches do not happen because someone breaks a password.
They happen because attackers steal a login session that MFA already approved. This technique is called session hijacking or token theft.
What Is Session Hijacking? (Plain English)
After you log in successfully, Microsoft creates a session so you do not have to keep signing in.
Session hijacking happens when:
- You log in normally
- MFA is approved
- An attacker quietly steals that session
- They reuse it with no password or MFA needed
MFA worked.
The session is what was abused.
How Session Hijacking Happens (Timeline)
This is a very common real-world attack:
| Step | What Happens |
|---|---|
| 1. Fake Microsoft message | User clicks a realistic email or link such as a shared file, invoice, or DocuSign request. |
| 2. Password entered | User types their correct password. |
| 3. MFA approved | User approves the MFA prompt. |
| 4. Session created | Microsoft issues a valid login session. |
| 5. Session stolen | The attacker steals that session immediately. |
| 6. MFA bypassed | The attacker reuses the session with no password or MFA required. |
The Security Gap in Business Standard
With Microsoft 365 Business Standard:
- MFA protects the login
- Sessions can stay active for days or weeks
- Stolen sessions can be reused silently
- Sessions cannot be shortened or restricted
In short:
Business Standard protects the sign-in, not the session.
What Business Premium Fixes
Microsoft 365 Business Premium adds security after login:
- Sessions expire in hours, not days
- Browsers cannot stay logged in indefinitely
- Company computers are trusted while unknown computers are restricted
- The most common session hijacking paths are blocked
| Product | Login Protection | Session Duration | Session Security | Device Trust | Session Hijacking Protection |
|---|---|---|---|---|---|
| Microsoft 365 Business Standard | MFA protects the login | Days or weeks | Stolen sessions can be reused silently | Not available | Sessions cannot be shortened or restricted |
| Microsoft 365 Business Premium | Adds security after login | Hours, not days | Browser persistence is limited | Trusted company devices | Common session hijacking paths are blocked |
Simple way to think about it:
Standard checks who you are.
Premium controls how long access lasts and where it is allowed.
Pricing (Monthly Commitment, USD per User)
Most of our clients prefer monthly billing, so here is the real comparison. This includes the Business Standard price increase coming July 1, 2026.
Note: Microsoft prices monthly commitments at roughly a 20 percent premium over annual pricing.
| Plan | Monthly Price (Today) | Monthly Price After July 1, 2026 | What You Get |
|---|---|---|---|
| Business Standard | About $15 | About $17 to $18 | MFA only with long-lived sessions |
| Business Premium | About $26 to $27 | About $26 to $27 with no increase | Session protection, device trust, and advanced security |
Why this matters:
- Business Standard is getting more expensive without fixing the security gap
- Business Premium pricing is not increasing
- The difference is the cost of a coffee or two per user per month
Why This Matters Now
- Session hijacking bypasses passwords and MFA
- Many Microsoft 365 breaches happen even when MFA is enabled
- The lower-cost license is going up while the more secure one is not
For most businesses, Business Premium is no longer extra security. It is baseline protection.
Seriously Consider The upgrade
If your organization is currently on Microsoft 365 Business Standard, now is the right time to talk about upgrading to Business Premium.
- Monthly billing with no long-term lock-in
- A smaller price jump than it first appears
- Closes a real, modern security gap that MFA alone cannot fix
Let us review what the upgrade would look like for your team.
We will explain the impact, cost, and security benefits in plain English.
This is not about buying more Microsoft licenses.
It is about reducing a risk that Business Standard simply cannot address.
