For most businesses, most of the communication between your business and the outside world occurs by email. While email is necessary for business, it also exposes your business to a variety of threats from time-wasting spam to data theft, hacking and viruses.
Barracuda’s Email Security Service is the most comprehensive and cost-effective way to protect your business against all of the threats associated with business email. In a single solution, you get effective protection against:
The Barracuda Email Security Service quickly filters every email before it hits your mail server to protect against inbound malware, spam, phishing and Denial of Service attacks.
The service is powered by Barracuda Central, our global 24x7 threat operations center that constantly monitors the Internet for new email-borne threats. The service is continuously updated with the latest threat definitions and software updates which means zero maintenance cost to you.
Our scalable cloud and prioritized filtering technology ensures that you get the best possible level of protection without adding significant delays to the time it takes to receive emails – even during peak load times during the day.
Outbound filtering keeps sensitive data from leaving your organization while simultaneously ensuring that legitimate emails are delivered. At the same time, outbound filtering also 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 viruses.
Administrators can also create and enforce content policies to prevent sensitive data such as credit card numbers, social security numbers, HIPAA data, customer lists and other private information from being sent by email. Policies can automatically encrypt, quarantine or even block certain outbound emails based on their content, sender or recipient.
Your emails can travel through many different servers before they reach the intended mailbox. The Barracuda Email Security Service 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.
All of the encryption in the world is meaningless if your emails don’t get delivered. In the event of a disruption in your mail server, email can be spooled on Barracuda’s Cloud Protection Layer for up to 96 hours. An alternate destination can also be specified for delivery if delivery to the primary destination fails.
Whether you manage your own mail server such as Microsoft Exchange or use a hosted service like Office 365, the Barracuda Email Security Service takes only minutes to set up. Regardless of where your email resides, the Barracuda E-mail Security Service gives you much greater control and protection over your email communication.
For a purely on-premises solution, we also offer the Barracuda Spam Firewall which provides the same features as the Barracuda Email Security Service in a plug-in hardware appliance or a downloadable virtual appliance. The on-premises appliance automatically connects to our secure cloud to get the latest threat definitions and software updates, as well as to offload processing during peak load times and to spool emails in case your mail server goes down.
