What Barracuda adds on top of Microsoft 365
Exchange Online Protection catches known spam, but sophisticated phishing and BEC regularly slip through. Here's what a managed Barracuda deployment adds.
Catches what Exchange Online Protection misses
Microsoft 365's built-in filtering stops commodity spam but regularly misses business email compromise and zero-day phishing. Barracuda re-scans every message with AI-driven detection tuned to catch what EOP lets through.
No MX record changes
Barracuda connects to Microsoft 365 directly via API, so your existing mail flow and rules stay untouched. Deployment is typically complete within a few business days.
Automated incident response
If a threat still reaches an inbox, it's automatically removed from every mailbox it touched — no manual hunting through message trace.
