Barracuda's Essentials for Email Security protects your organization with comprehensive, scalable and affordable multi-layer security and archiving whether you use on-premises email like Microsoft Exchange, or a cloud-based productivity suite like Google Apps for Work or Education.
Email continues to be a primary communication channel and thus is also one of the most frequently exploited threat vectors. Email-borne data breaches, data leaks, business disruptions as well as compliance and litigation searches cost money and reputation.
In addition to spam-based attacks, email threats have evolved to highly sophisticated phishing campaigns, targeted zero-hour attacks and data theft aimed at exploiting risky user behavior. With 91% of hacks starting with a targeted email attack, organizations need to protect their users, data and assets. If you are running Exchange on-premises or it is hosted in the cloud, you also have to deal with the added challenge of email and business continuity.
Compliance and preservation of email is now a key requirement for many organizations, and the penalties for not meeting business and governmental regulations can be severe.
Barracuda Essentials for Email Security combines several layers of protection for inbound and outbound email to secure against the most advanced email borne attacks, email spooling to ensure business continuity, and archiving for organizations to meet demanding compliance and preservation requirements and address eDiscovery requests effectively and easily.
The Barracuda Essentials for Email Security quickly filters every email before it hits your mail server to protect against inbound malware, spam, phishing and Denial of Service attacks. Features include sender spoof protection, domain name validation and anti-fraud intelligence.
The service is powered by Barracuda Central, our global 24x7 threat operations center that constantly monitors the Internet for new email-borne threats across all attack vectors. The service is continuously updated with the latest threat definitions intelligence 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.
Our Advanced Threat Detection goes beyond inbound email filtering to provide comprehensive protection from targeted attacks that may contain malicious links and attachments. We utilize a full system emulation sandbox to prevent suspicious URLs and files from reaching your users.
- Barracuda Link Protection detects malicious and malformed URLs at click-time, and redirects them to our sandbox so users are protected from potential malware and ransomware.
- Available Advanced Threat Detection opens suspicious attachments in our sandbox and detonates them in real-time to protect users from these highly-effective, socially-engineered attacks.
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 Essentials for Email Security 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.
Compliance is now a key requirement for many organizations, and the penalties for not meeting business and governmental regulations can be severe. These must be implemented in all areas across the organization to demonstrate and ensure that the business is operating in a compliant manner and to minimize ongoing legal risk. Barracuda Cloud Archiving Service takes a policy-based approach to meeting this need, automating and enforcing both the retention and the deletion of email as required. With Barracuda Cloud Archiving Service, you save only what is needed and only for the time that it needs to be saved, and you can be confident that your day?to?day email operations meet government and regulatory compliance standards. In response to regulatory audits, you can demonstrate adherence to retention and defensible deletion policies.
