Email Encryption

Your emails can travel through many different servers before they reach the intended mailbox. Barracuda secures your mail by encrypting it during transport to the Barracuda Message Center, encrypting it at rest for storage in the cloud, and providing secure retrieval by your recipients through HTTPS Web access. Data in motion is secured via Transport Layer Security (TLS) and data at rest is secured via AES 256-bit encryption.

If you are sending a sensitive email, you can manually mark it for encryption. However, you can also create a policy to automatically encrypt emails based on their sender, content and other criteria. Encryption policies ensure that your organization complies with regulations designed to protect customer data, such as HIPAA.

Data Loss Prevention

Outbound filtering keeps sensitive data from leaving your organization while simultaneously ensuring that legitimate emails are delivered. At the same time, outbound filtering blocks outbound spam and viruses, preventing your employees or other infected clients from inadvertently sending malicious email, as well as keeping your mail server IP addresses and domains from being listed on spam-block lists.

Employees can inadvertently allow their email to be used for botnet spam. The outbound filter stops outbound spam and the spread of viruses.

Administrators can also create and enforce content policies to prevent sensitive data from being sent by email, such as credit card numbers, Social Security numbers, HIPAA data, customer lists, and other private information. Policies can automatically encrypt, quarantine, or block certain outbound emails based on their content, sender, or recipient.
