What makes it different

Easy to deploy and operate

API-based setup with no MX record changes, no mail-flow disruption and no manual configuration. Works alongside your existing Microsoft 365 or Google Workspace setup. You’re protected today, not weeks from now.

Continuous post-delivery protection

Unlike traditional gateways and native controls that end at delivery, Barracuda continuously monitors what happens after email arrives. When a link weaponizes three days later, Barracuda detects and removes it. When an account gets compromised and starts sending phishing emails internally, Barracuda detects the compromise, locks attackers out, retroactively reevaluates every email from that account, and removes them across all mailboxes — automatically, within seconds.

Protection beyond the inbox

Attacks don’t stay in email. They move to identity, network and data. Barracuda pairs autonomous remediation with telemetry from threat intelligence, URL activity and BarracudaONE® identity, endpoint and network signals. Threats are stopped before they escalate into broader incidents.

AI you can understand and control

Barracuda’s Bailey™ assistant provides plain-language explanations for every decision: Why was this email flagged? What signals triggered the action? You can review the reasoning, get a unified view of verdicts from Barracuda, Microsoft and Google, which makes security decisions easier. You stay in control while AI handles the heavy lifting.

Built for MSPs

MSPs face a specific challenge: Customer attack volume is increasing, but operational capacity cannot scale at the same rate. Barracuda Integrated Email Protection addresses this directly:

Multi-tenant operations

• Real-time tenant-wide clawback across all affected customer tenants from a single action
• Unified investigation and response eliminates console switching
• Automated mailbox cleanup — no manual SOC steps for standard remediation

Operational efficiency

• API-first deployment means minutes, not days per tenant
• Transparent, predictable pricing with no surprise renewal increases
• Scales profitably without adding headcount

Measurable differentiation

Your customers compare you to Microsoft 365 native security. With Barracuda, you show measurable value through integrated reporting that quantifies threats stopped before, at and after delivery — clearly demonstrating what native controls miss.

The bottom line

Email security used to be about stopping spam. Then it was about stopping phishing at delivery.

Now it’s about stopping attacks that evolve after they arrive, move beyond the inbox and weaponize identities to spread across your entire environment in minutes.

Barracuda Integrated Email Protection is built for that reality — and for teams that need protection that actually fits how they work.
