Barracuda Integrated Email Protection Features
Explore integrated email protection features including impersonation and phishing protection, automated incident response, and domain fraud protection.
Threat Detection
Behavioural AI
Barracuda uses advanced analysis to understand normal email behaviour, such as who communicates with whom, how messages are written and typical timing patterns, to identify suspicious activity. By focusing on behaviour instead of static rules or signatures, Barracuda Integrated Email Protection can detect sophisticated threats that blend in with everyday email.
Natural language processing and intent analysis
Barracuda Integrated Email Protection analyses the language and intent of email messages to understand what an email is trying to do—not just how it looks. By evaluating context, tone and the nature of the request, Barracuda can identify social engineering, phishing and impersonation attacks that are designed to sound legitimate and bypass traditional keyword or rule‑based detection.
Social graph analysis
Analyse trusted relationships in your organisation to spot unusual or unexpected interactions. This ability helps detect impersonation and business email compromise attempts, including first‑time sender attacks and messages that abuse established trust between employees, partners or executives.
Language-agnostic phishing detection
Detect phishing and impersonation attacks written in multiple languages, not just English. This ensures consistent protection for global organisations, helping prevent threats that target users in specific regions or rely on language differences to bypass traditional filters.
Real-time URL analysis
Barracuda Integrated Email Protection continuously inspects links to see where they actually lead and how they behave at the moment a user interacts with them. By following redirects, analysing destinations and detecting suspicious behaviour in real time, Barracuda Integrated Email Protection stops malicious links that evade reputation checks or become weaponised after delivery without relying on user clicks or time-of-click inspection, enabling earlier and more accurate detection of evasive threats.
Post-Delivery Response
Deep URL scanning
Barracuda re‑scans delivered email links using post‑delivery deep URL scanning, sandboxing and rendering destination webpages to detect delayed and evasive threats that only emerge after delivery.
Post-delivery clawback
Post‑delivery clawback automatically removes emails that become malicious after delivery, closing the post-delivery gap attackers rely on to launch delayed phishing and link‑based attacks. By monitoring delivered messages and acting the moment risk changes, Barracuda Integrated Email Protection eliminates the need for manual cleanup or user reporting, which prevents evolving threats from turning into account takeover.
Automatic remediation
Automatically remediate email messages that contain malicious URLs or attachments. All user-reported messages are automatically scanned for malicious content. When a threat is detected, all matching emails are moved from users’ mailboxes into their junk folders. Security teams will get an alert notifying them of an incident.
Continuous learning loops
Barracuda continuously improves detection by learning from real‑world attacks, customer feedback and global threat intelligence. As attacker tactics evolve, detection models are retrained automatically, helping reduce false positives, improve accuracy and strengthen protection over time.
Account Takeover Protection
Alerting for account takeover
By detecting anomalies in internal employee communications, Barracuda can automatically detect when employee accounts become compromised and are used to send malicious emails to internal and external recipients. Administrators get alerted when an account has been compromised, and they can take immediate action.
Detect suspicious logins and unusual activity
Detect suspicious logins by tracking Internet Protocol (IP) addresses that exhibit suspicious behaviour, such as failed sign-ins, and share intelligence across all users and accounts. Track each user’s access patterns and alert IT administrators when Barracuda observes unusual sign-in activity, such as from an unusual device or geography. The AI tracks user-level and organisation-wide patterns.
Inbox rule change monitoring
Changes to a user’s email inbox rules can potentially indicate an account takeover. Barracuda detects and alerts on unauthorised inbox rule modifications, which provides visibility across the entire email environment.
Identify users who interacted with malicious emails
Identify all users who received malicious emails and clicked on links, replied to or forwarded these messages. Automatically send them email notifications with instructions to change their passwords and other necessary remediation actions.
Send alerts to users
Use Barracuda Integrated Email Protection to identify users who received malicious email and automatically send alerts notifying them of an incident. These emails can be sent in bulk to all affected users.
Automated response playbooks
Build custom playbooks to completely automate your response process. Admins at any technical level can create a workflow and add complexity by defining a trigger, determining conditions and assigning the desired actions through a simple user interface.
Report suspicious messages
Users can report phishing and other suspicious emails to their IT administrators directly from the Outlook Essentials Message Actions add-in. This feature provides end users with a simpler way to report suspicious emails to their IT department. Reported messages will appear in the dashboard for IT to review, investigate and take corrective action.
Domain Fraud Protection
SPF and DKIM validation to verify sender authenticity
Barracuda helps customers correctly configure their DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF), as well as troubleshoot common problems, such as domain misalignment.
DMARC aggregation and visualization
Customers can get high-level insights on the different email systems sending emails with their domains and gain access to in-depth information, including which IPs are passing and failing Domain-based Message Authentication (DMARC), domain misalignment and spoofing samples.
Protection against direct domain spoofing and lookalike abuse
Barracuda’s domain fraud protection prevents third parties from maliciously spoofing domains. Barracuda Integrated Email Protection leverages DMARC to gain visibility into legitimate and non-legitimate emails being sent with a particular domain and enables customers to make sure their legitimate emails are delivered correctly while blocking the malicious senders.
Operational Simplicity and Visibility
Unified with Microsoft quarantine
Combine all quarantined emails into a single, centralised view, giving administrators full control from one place. By eliminating the need to switch between consoles, teams improve visibility across email security layers and can review, release or delete quarantined messages faster and with greater confidence.
Value reporting
Value reporting clearly shows where email threats are stopped so you can see exactly how Barracuda Integrated Email Protection complements native security, prove ROI and understand where real risk remains.
Bailey™ explainable AI
Explainable AI with Bailey provides clear, AI‑assisted explanations that show why an email was blocked or allowed, using plain language. By translating complex detection signals into easy‑to‑understand insights, Bailey helps you quickly confirm decisions, resolve false positives and act with confidence.
API-based deployment – no MX record changes
Barracuda uses application programming interfaces (APIs) to connect directly to your environment. The APIs allow the AI to learn customer historical communication patterns and detect, block, quarantine, and clawback emails in real time. It’s a cloud-based SaaS solution that requires no mail exchange (MX) record changes, maintenance or installation.
BarracudaONE platform management
Barracuda Integrated Email Protection — managed through our unified BarracudaONE cloud‑based platform—brings visibility, control and response into a single experience. BarracudaONE provides a centralised view of email activity across gateway and API‑based protections, enabling administrators and managed service providers (MSPs) to manage policies, investigate messages and remediate threats from one interface. By reducing tool switching and simplifying day‑to‑day operations, BarracudaONE helps teams respond faster, operate more consistently across tenants and manage email security with lower operational overhead.
