91% of cyberattacks start with an email.

Protect your data from corruption and deletion with full cloud backup and recovery of every email and file. Keep sensitive data safe with data leak prevention and encryption.
Stop spam and malware with inbound filtering.
Barracuda quickly filters and sanitizes every email before it’s delivered to your mail server to protect you from email-borne threats. Using virus scanning, spam scoring, real-time intent analysis, URL link protection, reputation checks, and other techniques, Barracuda provides you with the best possible level of protection.
Barracuda Central, our global 24×7 threat operations center, constantly monitors the internet for new threats across all attack vectors and feeds this intelligence into email filtering technology.
Block advanced threats.
Some of the most dangerous advanced threats are designed to evade email filters. Barracuda leverages Advanced Threat Protection, a cloud-based service that defends against ransomware and other malware, including zero-day attacks and advanced threats.
We don’t believe this level of security has to come at the price of performance. Barracuda uses multiple, layered analytic engines, including behavioral analytics, static analysis, and CPU-emulation sandboxing to detect unknown and evasive threats.
Block malicious email links.
Hackers and spammers include links in emails that trick people into giving up sensitive information or take them to a malicious site that could spread malware. Organizations can protect their users from accessing this malicious content with Barracuda link protection.
Barracuda automatically rewrites an inbound deceptive URL in an email message and performs real-time analysis of URLs and domains at time-of-click. Users are safely redirected to a valid domain or to a Barracuda domain warning of the fraud. Rewritten URLs do not expire and function indefinitely.
Protect outbound email and stop data leaks.
Employees can inadvertently cause internal systems to become a source for spam or other malicious mail. Outbound filtering stops outbound attacks originating from inside the network, which protects your partners and customers and also keeps you from being added to spam-block lists.
Barracuda data-loss protection and email encryption keeps sensitive data — such as credit card numbers, Social Security numbers, HIPAA data, and more — from leaving your organization. Content policies can automatically encrypt, quarantine, or block certain outbound emails based on their content, sender, or recipient.
Stay connected and productive during downtime.
In the event of a mail server outage or loss of connectivity, Barracuda Email Continuity ensures that email operations continue by failing over to our cloud-based email service. An emergency mailbox lets users continue to send and receive emails, staying productive until your primary servers are back online.
Inbound Email Security
- Advanced Threat Protection
Barracuda’s Advanced Threat Protection (ATP) combines behavioral, heuristic, and sandboxing technologies to protect against zero-hour and targeted attacks. ATP automatically scans email attachments in real time; suspicious attachments are detonated in a sandbox environment to observe behavior. In addition to blocking the attachment, the results are integrated into Barracuda Real-Time System providing protection for all other customers.

- Anti-Phishing Protection
The Barracuda combats phishing attempts by combining anti-fraud intelligence, behavioral and heuristic detection, protection against sender spoofing (i.e., spammers spoofing valid email addresses), along with domain name validation to detect and block phishing attempts.
For protection against social engineering attacks, review our Impersonation Protection.
- Malware Protection
Barracuda leverages the cloud for dynamic, real-time threat analysis, attachment sandboxing, and URL protection to prevent malware from affecting email users.
- Link Protection
A popular method that attackers use to deliver malware relies on URLs that contain malicious code, which can be invisibly downloaded and can trigger a much larger attack. Link Protection automatically rewrites these URLs so that Barracuda can sandbox the request at click time to block malicious links. Rewritten URLs do not expire and function indefinitely.
- Typosquatting protection
More sophisticated attackers make clever modifications to URLs so they look genuine, but are not. The most common technique is omitting letters or using convincing “typos” that even users who check URLs before clicking often miss. Barracuda’s Link Protection includes typosquatting detection, which automatically identifies and redirects these URLs to our sandbox at click time to block malicious activity.
- Spam Filtering
With a long-standing heritage in spam protection, Barracuda remains the leader in identifying and blocking spam. A comprehensive set of security layers ensures that organizations remain productive in the face of evolving threats.
Barracuda identifies email from known spammers and determines whether domains embedded in email lead to known spam or malware domains. It leverages industry-leading techniques that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.
- Block email-borne viruses
As virus attacks become more sophisticated and complex, email infrastructure requires advanced virus protection. The potential for the destruction and release of information or the disruption of a network severely impacts productivity and can lead to financial loss.
Barracuda scans email and incoming files using three powerful layers of polymorphic virus scanning technologies. It also decompresses archives for complete protection. Powerful virus definitions are automatically updated to maintain the most up-to-date protection against email-borne viruses.
- Denial of service (DoS) attack prevention
Not every attack is focused on planting a virus or getting users to send their credit card number or to click on a malicious link. Often, the objective of the attack is focused on disabling a network or mitigating its effectiveness. As a cloud-based service Barracuda Email Protection is positioned to stop spammers before they overload an email server.
- Outbound Email SecurityOutbound email security
Outbound filtering prevents organizations from being put on spam block lists and prevents outbound attacks originating from inside the network. Employees can inadvertently cause internal systems to become a source for botnet spam. Using a subset of its defense layers, Barracuda’s outbound filtering stops outbound spam and viruses.
- Email ContinuityEmail service continuity
Barracuda Email Continuity Service ensures that email operations continue by failing over to a cloud-based email service in the event primary email services become unavailable. During email server outages, an emergency mailbox allows users to continue sending, receiving, reading, and responding to email.
Simplified Email Management
- Cloud-based management
Barracuda Email Protection is integrated with the Barracuda Cloud Control web-based management portal, which leverages Barracuda’s global cloud infrastructure and provides a global view to centrally manage all of Barracuda’s solutions through a “single pane of glass” interface. Barracuda Cloud Control also allows administrators to centrally manage policies and configuration. The simple interface makes it easy for organizations to implement and manage the service with minimal IT overhead.
