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 the Barracuda Real Time System providing protection for all other customers.

Malware Protection

The Barracuda Essentials for Email Security leverages the cloud for dynamic, real time threat analysis, attachment sandboxing and URL protection to prevent malware from affecting email users.

Link Protection

Anti-phishing also includes 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 the Barracuda Essentials for Email Security can sandbox the request at click time to block malicious links.

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.

Integrated End-User Security Training

By integrating end-user security education and training exercises into the Barracuda Email Security technology, users that click on malicious links are taken to a landing page where they can take training exercises to understand what they did wrong and how to avoid repeating this mistake moving forward. The exercises run about five minutes and take the user through a course to understand who is behind these attacks, what to look for, and a test to ensure they can apply what they’ve just learned.

Anti-Spam Protection

With a long-standing heritage in spam protection, Barracuda Networks 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.

The Barracuda Essentials for Email Security leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains. It leverages many of the same industry-leading techniques found in the Barracuda Spam Firewall that protect against attempts to embed text inside images with the intent of hiding content from traditional spam filters.

Anti-Virus Protection

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.

The Barracuda Essentials for Email Security 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.

Agentless Email Encryption

The Barracuda Essentials for Email Security offers a number of encryption features without requiring complicated key management. It is fully integrated with a cloud-based email encryption service for outbound email. Email that matches policy is securely sent via TLS to the Barracuda Message Center.

The Barracuda Message Center uses AES with 256-bit keys to encrypt emails. To encrypt email traffic between sites over the Internet, the Barracuda Essentials for Email Security supports SMTP over TLS. This can be used between organizations that leverage a Barracuda email security solution or other email servers that support SMTP over TLS.

Outbound Filtering

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, the Barracuda Essentials for Email Security’s outbound filtering stops outbound spam and viruses.

Data Leak Prevention

Sensitive data abounds in company networks, and it is far too easy to send this information out of the company via email. Data Leak Prevention allows administrators to configure policies that will automatically recognize sensitive content. This content can be as straightforward as credit card numbers and social security numbers which are identified by predefined filters, as well as data that conforms to any number of custom policies. When sensitive information is detected in outbound mail, it can either be blocked or automatically encrypted, again, based on configurable policies.

Email Continuity

The 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.

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, the Barracuda Essentials for Email Security is positioned to stop spammers before they overload an email server.

Archiving, Compliance and eDiscovery

The Barracuda Cloud Archiving Service assists organizations with compliance and eDiscovery requests effectively and easily when used with Microsoft Exchange, Google Apps, and other on-premises, cloud or hybrid environments. It offers productivity features, including mobile applications for end users to search and retrieve email at any time from any device. The Barracuda Cloud Archiving Service creates a cloud-based indexed archive. This allows granular retention policies, extensive search, auditing/permissions, legal hold and export, helping to facilitate compliance retention and eDiscovery preservation. Legal holds preserve email from being tampered with until it?s removed. Native and mobile apps provide intuitive interfaces that ensure messages are found easily. The Barracuda Cloud Archiving Service creates an indexed archive to support extensive search, auditing/permissions, legal hold and export, helping facilitate eDiscovery and retention. These easy-to-use search capabilities, ranging from the most basic search by a user for a misplaced email to advanced Boolean search strategies for an auditor during an eDiscovery request.

Simple Cloud-Based Management

An intuitive web interface makes administering the Barracuda Essentials for Email Security easy and straightforward. With no hardware to install, initial deployment takes less than 30 minutes.

While the default settings are often all that many organizations ever need, the Barracuda Essentials for Email Security has a broad range of settings that can be customized to meet special requirements. For example, some email sources can be whitelisted to bypass filtering, while other sources can be blacklisted for complete blocking. Administrators can customize filters independently for inbound and outbound email to selectively prevent passage of email content that is sensitive in nature or contrary to an organization’s objectives and standards.

Customers that use several Barracuda products (such as Office 365 users running Barracuda Essentials, which combines email security with data protection features)can manage all their Barracuda products from a single interface: the Barracuda Cloud Control (BCC). This web-based management portal leverages Barracuda’s global cloud infrastructure to enable organizations to centrally manage all their Barracuda products through a “single pane of glass” interface. Administrators gain a global view of all their devices or services, as well as centrally manage policies and configuration. The simple interface makes it easy for organizations to implement and manage multiple services with minimal IT overhead.
