Microsoft 365 Business Premium: do I need Proofpoint?
Not necessarily. Microsoft 365 Business Premium already includes advanced email protection (Defender for Office 365): links checked when clicked, attachment scanning and phishing filtering. For basic protection, this largely overlaps with Proofpoint Business and Advanced.
Proofpoint is still useful with Business Premium in three cases:
- Legal email archiving for 10 years: included in Proofpoint Professional, not in Business Premium.
- Business continuity: if Microsoft 365 is down, your staff keep reading and sending email from a backup mailbox (Emergency Inbox).
- High exposure to payment fraud: the "Plus" plans add advanced CEO fraud detection (Advanced BEC Defense).
With Microsoft 365 Business Basic or Standard, which only have basic filtering, Proofpoint adds a real extra layer of protection. If in doubt, our team will advise you.
