Keep Communication Private with Email Encryption

A simple and automated approach to encryption and data protection.

Go Beyond Traditional Email Encryption

Deploying standalone email encryption services can be so cumbersome to manage and use that many users decide to bypass their organizations' secure communication policies. Barracuda Essentials provides simple email encryption that is extremely secure and part of a complete email protection solution. More important, Barracuda combines email encryption with other layers of data protection including data leak prevention, archiving, and filtering that blocks malware and advanced threats.

Secure Data-at-Rest and Data-in-Motion

Transport Layer Security (TLS) provides a secure channel for data transmission, and ensures that all content, emails, and attachments are encrypted during transit. This is known as data-in-motion security, because the data is secure during the actual transmission process.

However, TLS does not provide any security for data at rest. This means that your emails and attachments may be unprotected while stored on sending and receiving servers, or on other servers and gateways that handle emails in transit. Because of this, TLS by itself does not allow you to guarantee the security of your emails.

Barracuda encrypts all email and attachments on every server where they reside. If a user replies to an encrypted message, the reply is also automatically encrypted.

AES-256 Encryption with Automatic Key Management

AES-256 Encryption with Automatic Key Management

Barracuda uses 256-bit keys, commonly known as AES-256, to secure all encrypted emails. The keys are stored in Barracuda's geographically distributed data centers with multiple data copies to provide redundancy. The data centers maintain strict physical security and access control. As an added measure of control, the data centers and the keys used to encrypt the data are stored in separate areas.

Once an email is encrypted, a notification is sent to the recipient with a link to the Barracuda Message Center. Access to the message requires HTTPS. The recipient will be required to create a password for first-time access and then use this password for all subsequent access. Any replies are also sent via the Barracuda Message Center to ensure security.

For encryption to work, you must ensure that it is used on email that might contain sensitive or legally protected information. This is critical for heavily regulated industries such as healthcare, finance, and legal organizations, which are required to secure certain categories of data.

With Barracuda, you can easily create policies to automatically encrypt emails based on the sender, recipient, keywords, domain, or many other criteria. This provides a safe and reliable way to share sensitive information with customers and partners. It reduces potential risk of data loss, while facilitating regulatory compliance.

Data Protection that Goes Beyond Encryption

Data Protection that Goes Beyond Encryption

Email encryption can control who is able to access email once it leaves your organization. However, it doesn't stop unauthorized users from sending emails that contain sensitive data such as credit card numbers, social security numbers, or HIPAA-protected information. Data Leak Prevention (DLP) automatically scans every outbound email for sensitive content. Based on the content, the email can be automatically encrypted, quarantined, or even blocked.

Your data is further protected by email archiving that ensures that email retention policies are enforced with a tamper-proof copy of all email communication. In addition, Barracuda provides a full cloud-based backup of every email to protect your data if your mail server becomes unavailable or important emails are deleted by users.

Integrated Protection from Viruses, Malware, and Advanced Threats

Email is the number-one threat vector for cyber attacks. Securing your email requires more than just message encryption. Your data can also be targeted by hackers via email impersonation, spear phishing, and ransomware.

Barracuda Essentials was built as a true, all-in-one email protection platform. It includes filtering of every inbound and outbound email for spam, viruses, malware, and advanced threats like phishing. Barracuda also includes powerful AI-based scanning of emails to stop highly targeted threats like email impersonation, spear phishing, and account takeover. And our email continuity service ensures that emails are delivered even if your mail server goes down.
