    Barracuda Email Security Gateway Platform Capabilities

    The Barracuda Email Security Gateway offers unmatched protection against email-borne threats with its advanced threat detection and data loss prevention capabilities, ensuring robust security for businesses of all sizes.

    Barracuda’s Advanced Threat Protection (ATP) is a sophisticated security feature that utilizes a blend of behavioral analysis, heuristic algorithms, and sandboxing technologies to defend against zero-hour and targeted cyber attacks. This system actively scans email attachments in real-time. If an attachment appears suspicious, ATP detonates it within a secure sandbox environment to analyze its behavior. This proactive approach not only blocks dangerous attachments but also feeds the analysis results into the Barracuda Real Time Intelligence System. This integration enhances the overall security network, extending protection based on these insights to all Barracuda customers, thereby continuously improving the system’s effectiveness against emerging threats.

    Spam Protection

    Barracuda Networks, with its well-established reputation in spam protection, continues to lead the industry in identifying and blocking spam. The Barracuda Email Security Gateway employs a multi-layered security approach to ensure organizational productivity amidst constantly evolving threats.

    Key to its effectiveness is the use of Barracuda Central, a powerful intelligence system that identifies emails from known spammers and checks if domains in emails are linked to spam or malware. Additionally, Barracuda sets the standard in its ability to thwart advanced spamming techniques, such as embedding text within images—a method used to evade detection by conventional spam filters. This comprehensive and advanced approach to email security positions the Barracuda Email Security Gateway as a formidable tool in protecting against spam and other email-borne threats.

    As the sophistication of virus attacks increases, the need for advanced virus protection in email infrastructures becomes critical. The risk these viruses pose includes the potential destruction or unauthorized release of information, as well as disruptions to network operations, which can severely hinder productivity and result in financial losses.

    Addressing this, the Barracuda Email Security Gateway employs a triple-layered virus scanning approach to thoroughly scan emails and incoming files. This includes the capability to decompress archive files, ensuring comprehensive protection. The gateway’s powerful virus definitions are constantly refreshed through Energize Updates, maintaining up-to-date defenses against the latest email-borne viruses.

    Additionally, to counteract the threat of internal email-borne viruses that may bypass the email gateway, the Barracuda Email Security Gateway integrates with a Microsoft Exchange Plug-In. This plug-in provides an additional layer of security within the organization, safeguarding against the spread of viruses internally. Regular updates to the virus definitions further bolster the system’s ability to provide the most current and effective protection against email-related virus threats.

    Indeed, not all cyber attacks aim to disseminate viruses or directly solicit sensitive information like credit card numbers through malicious links. Many attacks are strategically designed to compromise or entirely disable a network. In this context, the positioning of the Barracuda Email Security Gateway is crucial. As a device that is strategically placed in front of an email server, it acts as the first line of defense against spammers. Its primary role is to intercept and stop spam emails before they have the chance to overload or disrupt the email server. This proactive stance taken by the Barracuda Email Security Gateway is essential in preventing potential network compromises and ensuring the uninterrupted operation of email communication within an organization.

     

    The Barracuda Email Security Gateway offers a robust solution to ensure continuous email delivery, even in scenarios of email server failures or loss of connectivity. This is achieved through its Cloud Protection Layer (CPL), which serves as a fail-safe mechanism. In the event of disruptions to on-premises servers, the CPL can spool and hold emails for up to 96 hours, acting as a temporary storage buffer. Additionally, there is a provision for specifying an alternate destination for email delivery in case the primary destination is unavailable.

    During periods when email servers are down, the visibility and management of emails become crucial. The Cloud Protection Layer addresses this by allowing all spooled emails for the affected mail servers to be visible and managed through its system. Administrators can access the message log within the CPL to monitor the status of all spooled emails, including whether they have been successfully re-delivered. This feature not only ensures continuity in email communication during server outages but also provides administrators with the necessary tools to effectively manage email flow during such critical periods.

     

    The Barracuda Email Security Gateway is adeptly integrated with a cloud-based service, enhancing its efficiency and scalability. This integration allows for the pre-filtering of emails in the cloud before they are delivered to the on-premises Barracuda Email Security Gateway. The Cloud Protection Layer (CPL) involved in this process is constantly updated with the latest definitions in real time from Barracuda Central, ensuring up-to-date protection against emerging threats.

    Moreover, Barracuda’s global cloud infrastructure is a key component in managing fluctuations in email traffic. It is designed to handle surges in email volume that can occur at specific times of the day or during Denial of Service (DoS) attacks. This capability is crucial in maintaining the integrity and availability of email services under varying load conditions.

    The scalability provided by the Cloud Protection Layer is a significant advantage for organizations. As the volume of emails, the size of attachments, and the scale of the organization grow, the CPL ensures that the email security infrastructure can expand accordingly. By leveraging the bandwidth and computing power of the CPL, organizations can efficiently scale their email security solutions to meet their evolving needs, without compromising on performance or security.

     

    The Barracuda Email Security Gateway incorporates several robust encryption features, ensuring secure email communication, particularly for outbound emails. This is achieved through a full integration with a cloud-based email encryption service. When an email matches predefined security policies or is manually marked for encryption using the Barracuda Outlook Add-in, it is securely transmitted via Transport Layer Security (TLS) to the Barracuda Message Center.

    At the Barracuda Message Center, the Advanced Encryption Standard (AES) with 256-bit keys is employed to encrypt emails, providing a high level of security for sensitive information. Furthermore, to secure email traffic between different sites over the Internet, the Barracuda Email Security Gateway’s Message Transport Agent supports SMTP (Simple Mail Transfer Protocol) over TLS. This feature is compatible not only between Barracuda Email Security Gateways but also with other email servers that support SMTP over TLS. This versatility ensures that email communications are protected across different platforms and networks, making the Barracuda Email Security Gateway an effective solution for organizations looking to safeguard their email communications against interception and unauthorized access.

     

    Outbound filtering is a crucial feature of the Barracuda Email Security Gateway, serving two primary purposes: protecting organizations from being blacklisted as spam sources and preventing the unauthorized external transmission of sensitive email data. This aspect of email security is particularly important as employees, often unintentionally, can cause internal systems to become a source of botnet-generated spam.

    The Barracuda Email Security Gateway employs a subset of its comprehensive defense layers specifically for outbound filtering. This targeted approach effectively stops outbound spam and viruses, significantly reducing the risk of the organization’s email domain being compromised or misused for malicious activities.

    Moreover, the system empowers administrators to enforce stringent content policies for Data Loss Prevention (DLP). This is crucial for complying with various regulatory and corporate standards regarding the handling and transmission of sensitive information. The Gateway provides predefined filters and allows for the creation of custom policies, enabling the detection of sensitive data within outbound emails. Depending on the policy, these emails can then be blocked or encrypted. This functionality not only safeguards against data breaches but also ensures that outgoing communications adhere to set content standards, thereby maintaining the integrity and security of organizational communication channels.
