Threat Landscape
The AI era has fundamentally changed email attacks
AI has industrialized attacks
Phishing-as-a-Service kits now use automation to create attacks at scale. Every organization — regardless of size — faces the volume, sophistication and persistence of enterprise-level threats.
90%
of campaigns now use PaaS kits
Threats weaponize after delivery
Modern attacks look legitimate at delivery. Later, links rewrite and payloads activate — long after delivery-time protection has cleared the threat as “safe.” This makes point-in-time detection insufficient — continuous monitoring is required.
5 min
from inbox to identity theft
Email is the entry point to everything
A single phishing email can trigger account takeover, lateral movement, data exfiltration, and compliance violations. Once inside, attackers can delete, encrypt and steal data — making rapid recovery as critical as prevention.

How it works
Intelligent protection. Easy to manage. Complete coverage.
Protection across the full email security lifecycle — with continuous threat detection and response
Intelligent
AI that adapts as threats evolve — before and after delivery
Barracuda IQ™ uses multi-model AI to analyze intent, identity behavior and multi-modal content across 100+ global threat feeds. It continuously re-evaluates risk after delivery, catching threats that change, weaponize or evolve over time.
Multi-model AI analyzes intent, identity anomalies, continuously re-evaluating risk as threats evolve and reducing remediation from hours to instantaneous.
Detects compromised accounts from behavior signals, not just login anomalies, to catch identity takeovers.
Translates every detection decision into plain language, so your team stays in control.
Easy

Barracuda Email Protection deploys quickly, remediates automatically, consolidates alerts in one view, and scales with one-click bulk actions — so lean teams can stay protected without manual cleanup, alert fatigue or adding headcount.
Connects to Microsoft 365 or Google Workspace with no mail exchange (MX) changes — operational in minutes, not weeks.

The Platform
One platform stops the entire attack chain
Email is the entry point — but attacks don't stop there. BarracudaONE extends protection across identity and data, stopping attack chains before they escalate into business disruption.
Stop
attacks before business disruption starts
Strong protection blocks threats at the inbox, reducing noise and limiting how often teams need to respond. When attacks fail to reach users, your team maintains control without constant firefighting.
Identify
compromise before it spreads
When credentials are compromised, the clock starts ticking. Barracuda Cloud Security XDR detects account takeover and lateral movement, identifying a compromise before attackers reach critical systems and cause business disruption.
Contain
threats before they escalate
Automated response limits the blast radius, disabling compromised accounts in near real time before attacks spread. Fast containment with 24/7 SOC-backed coverage means incidents close quickly without expanding teams.
Restore
operations with confidence
Speed of recovery determines business impact. Integrated backup across email, data and identity enables fast restoration with the confidence that the environment is clean, minimizing downtime and getting teams back to work.
Extend Native Protection
Built for the platform your team already uses
Native security stops obvious threats but misses sophisticated attacks, creating email security gaps that attackers exploit. Barracuda Email Protection supplements Microsoft 365 and Google Workspace with stronger detection, behavioral account takeover identification and integrated backup for Microsoft 365 data.
