Modern attacks don’t stop at delivery. Neither does Barracuda.
Barracuda Integrated Email Protection is an API-based solution that strengthens Microsoft 365 and Google Workspace with high-efficacy, full-lifecycle protection. Powered by Barracuda IQ™, it continuously re-evaluates risk and removes threats in real time — making email security easy, keeping your team in control and reducing remediation time from hours to instantaneous.
Why must email security evolve for the AI era?
Email is no longer human-centric. As AI adoption grows, people and agents create and act on messages, expanding the attack surface beyond users. AI has made phishing cheap and easy to launch at scale, while today’s attacks exploit trusted identities, hijack conversations and often appear benign at delivery before evolving later. This makes traditional email security based on point-in-time detection insufficient to stop modern attacks.

How Barracuda protects you
How does Barracuda strengthen native email security?
Barracuda integrates directly with Microsoft 365 and Google Workspace via API-based email security, continuously detecting, re-evaluating and automatically remediating threats. It deploys in minutes with no Mail Exchange (MX) record changes, no mail-flow disruption and no manual configuration required.

Threat Detection
AI-driven detection adapts as threats evolve
Barracuda IQ is multi-model AI engine that analyzes message intent, links, identity behavior, and content across Microsoft 365 and Google Workspace environments, blocking threats out of the box. It continuously monitors for delayed phishing after delivery, rescans links and detects anomalies as risk changes. That helps stop business email compromise and socially engineered attacks that bypass built-in protections.

Account Takeover Protection
Detect and stop identity abuse inside the mailbox
Most solutions detect account takeover from login anomalies alone. Barracuda uses AI to detect account takeover from post-access email behavior — abnormal outbound patterns, inbox rule abuse and lateral phishing attempts — then automatically identifies and contains the threat before it spreads, so your team stays in control without manual security operations center (SOC) intervention.

Post-delivery Incident Response
Easy by design.
Automated by default.
Post-delivery remediation addresses threats that emerge or evolve after inbox delivery. It automatically reassesses delivered email as risk changes, fingerprints the threat and claws back every instance across the tenant via API in seconds to prevent spread across users and mailboxes. The Bailey™ assistant provides plain-language explanations, so your team stays in control while AI does the work.

Extend Native Protection
Built for the platform your team already uses
Native email security in Microsoft 365 and Google Workspace stops obvious threats at delivery, but today's most damaging attacks evolve after they arrive — exploiting trusted identities, hijacked conversations and delayed tactics that native controls weren't designed to stop.
Barracuda closes that gap with continuous detection, re-evaluation and remediation — stopping business email compromise, post-delivery weaponization, account takeover, and social engineering at scale.
