Essentials for Office 365

Multi-Layer Security, Backup, Archiving and e-Discovery for Office 365

Multi-Layer Security

Comprehensive Email Security:

Stop Email-Borne Threats before They Hit Your Mail Server

Outbound Email Protection:

Protect Critical Data from Leaving Your Business

Barracuda Essentials for Office 365 is a scalable, cloud-based email security solution that comprehensively protects organizations against advanced email-based attacks and data loss, and minimizes business disruptions. It includes enterprise-class technologies that leverage Barracuda’s advanced threat intelligence framework, gathering threat data across all network threat vectors. It also provides granular policy management and monitoring controls for customized rules.

Essentials for Office 365 protects against spam and viruses and known malware. Anti-phishing protection includes link protection which redirects malformed, suspicious, and typosquatted (a form of URL hijacking) links to a sandbox at time of click.

Barracuda Essentials for Office 365 also includes Advanced Threat Protection (ATP) for detecting sophisticated, zero-day, advanced persistent threats, and ransomware variants including Locky and CrytoLocker. ATP automatically scans email attachments in most commonly used file formats and opens any questionable content in a secure sandbox environment to detect malicious attachments.

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 the spread of 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.

Secure Your Communication with Email Encryption

Leverage the power of Barracuda Central

Your emails can travel through many different servers before they reach the intended mailbox. Barracuda Essentials for Office 365 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.

Our email protection leverages Barracuda Central to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware domains and is continually updated with intelligence on the latest threats across all threat vectors. Barracuda Central is a 24x7 centralized threat intelligence gathering organization, where the latest threats across all vectors are analyzed and added to our extensive databases. Over 170,000 organizations worldwide provide intelligence to Barracuda Central, and our email security is updated on a continuous basis.

Archiving, Compliance and eDiscovery

Granular Retention Policies

Powerful Search and eDiscovery

Barracuda Essentials for Office 365 provides a cloud-based archive of all email communication to ensure that you meet demanding business and legal requirements. It follows the accepted “best practice” approach for compliance by archiving an original copy of every email into a separate immutable store for long term retention and preservation.

Compliance and eDiscovery capabilities provided within Office 365 may be adequate for some organizations, but the “in-place” approach Microsoft takes for long-term email retention and preservation means these capabilities have inherent limitations. They can be complex and expensive to operate, and are unlikely to meet the needs of organizations with more demanding compliance and discovery requirements.

Barracuda Essentials for Office 365 includes a cloud-based, indexed archive separate from Office 365 that allows for granular retention policies, extensive search, auditing, permissions, legal hold and export of emails that may be required in eDiscovery. Litigation holds preserve email from being tampered with until the litigation hold expires or is removed.

The Barracuda Cloud Archiving Service offers easy-to-use search capabilities, ranging from the most basic search by a user for a misplaced email to advanced Boolean search strategies for an auditor during an eDiscovery request.

Barracuda offers native and mobile apps for Android and iOS that simplify search to ensure messages are found easily even when email services are unavailable. Mobile users can search, download and respond to any email ever sent or received, even if deleted from the server. Because all email is indexed, search is often much faster than typical native mobile email applications and provides a much higher search success rate. Users can forward, reply or resend email to themselves.

Backup, Recovery and Business Continuity

Email Service Continuity

Cloud-to-Cloud Backup and Recovery

The Email Continuity Service ensures that email operations continue by failing over to a cloud-based, email service, in the event Office 365 email services become unavailable. During email server outages, an emergency mailbox allows users to continue sending, receiving, reading, and responding to email.

Hosting production data in the cloud does not mitigate the need for backup and recovery. Emails and important documents are susceptible to corruption and risk being unrecoverable due to malicious attacks or even accidental deletion. Barracuda Essentials for Office 365 protects Exchange Online, SharePoint Online, and OneDrive for Business data by backing it up directly to Barracuda Cloud Storage.

Barracuda Backup is the world’s most widely used integrated backup appliance, according to IDC’s Purpose-Built Appliance Tracker. Barracuda Essentials for Office 365 utilizes Barracuda’s award-winning technology and data protection expertise to employee mailboxes in Exchange Online and corporate data hosted in SharePoint Online and OneDrive for Business for point-in-time recovery. These solutions can be deployed separately or together to cover your cloud-based data protection needs.

Simplified Email Management

Migrate Legacy Email Faster

Cloud-based Central Management

Office 365 makes email management simpler than on-premises solutions, but you first have to get your legacy emails to enjoy the benefits of cloud-based email access. For most organizations, this means a cumbersome process locating countless emails in disparate PST files and migrating them to the cloud.

Barracuda Essentials for Office 365 automates this migration with a 90 day subscription to Barracuda PST Enterprise. PST Enterprise will automatically discover PST files on network servers and end-user systems, and migrate this data to an archive or to Office 365. This gives IT administrators control over email data scattered across their organization. With all of your emails migrated to a single database, you minimize the risk of losing important emails and reduce the ongoing costs and support IT requirements for Compliance and eDiscovery.

Barracuda Essentials for Office 365 is integrated with the Barracuda Cloud Control web-based management portal, which leverages Barracuda’s global cloud infrastructure and provides a global view to centrally manage all of their Barracuda devices and services through a “single pane of glass” interface. Barracuda Cloud Control also allows administrators to centrally manage policies and configuration. The simple interface makes it easy for organizations to implement and manage the service with minimal IT overhead.

Integrated End-User Security Training

AI for Real-Time Spear Phishing and Cyber Fraud Defense

By integrating end-user security education and training exercises into the Barracuda Email Security technology, users that click on malicious links are taken to a landing page where they can take training exercises to understand what they did wrong and how to avoid repeating this mistake moving forward. The exercises run about five minutes and take the user through a course to understand who is behind these attacks, what to look for and a test to ensure they can apply what they’ve just learned.

As a complement to Barracuda Essentials, Barracuda Sentinel is the leading comprehensive AI solution for real-time spear phishing and cyber fraud defense. Delivered as a cloud service, Barracuda Sentinel combines a powerful artificial intelligence engine, domain fraud visibility using DMARC, and anti-fraud training into a comprehensive solution that protects people, businesses, and brands from spear phishing, impersonation attempts, business email compromise (BEC), and cyber fraud.


Office 365 already has security and archiving features. Why would I need additional protection?

It’s true that certain Office 365 plans come with Exchange Online Protection and Compliance Center which provides an initial layer of security. However, many companies that have a significant volume of email realize email security included with Office 365 can be hard to manage and lacks granular controls they relied on when they had on-premises email. There are also instances when spam and email-borne threats can still reach your in boxes.

In addition to adding another layer or more granular security, Barracuda Essentials adds important email retention, archiving and eDiscovery capabilities to Office 365. Many companies find email preservation in Office 365 is basic and doesn’t meet the needs of organizations facing any type of regulations or legal challenges.

Perhaps more importantly, it is never prudent to keep all of your emails in a single database with no backup or disaster recovery plan. Unfortunately, companies often realize too late that data can be lost due to user errors, corrupted file attachments and other problems outside the Microsoft cloud. Barracuda Essentials provides cloud-to-cloud backup of your emails and files to the Barracuda Cloud, OneDrive for Business or even to an on-premises server.

How does Barracuda add value to my Office 365 subscription?

Barracuda Essentials for Office 365 adds an additional level of protection from data loss while making your Office 365 implementation easier to manage.

Enhanced Email Security. The included email security service provides enhanced spam blocking and protection from email-borne threats such as malware, viruses and phishing emails. We also add a powerful, rules-based outbound email filter to prevent important data from leaving your organization. Email encryption adds yet another layer of security.

Cloud Archiving Service. Barracuda Essentials can use Office 365’s journaling feature to ensure that all emails are archived and can be easily searched.
Streamlined Backup and Recovery. The cloud-to-cloud backup service provides an unlimited backup of all of your emails and files, and the recovery process is much simpler and faster than the standard Office 365 recovery process.

How does Barracuda’s Email Security differ from Exchange Online Protection?
Barracuda Essentials provides additional layers of security to catch malware and phishing attempts which elude basic Exchange Online Protection. Barracuda Essentials also includes a number of features that are optional with Exchange Online Protection: advanced threat protection, anti-typosquatting protection, link protection and email encryption.
My Office 365 subscription includes the Compliance Center which has archiving and eDiscovery included. Why would I need another archive?
Barracuda takes an alternative approach, by capturing a single immutable copy of every email. It minimizes risk by storing this copy outside the production email environment in a separate secure archive repository in the Barracuda Cloud. This straightforward approach ensures that original email data will be stored securely for as long as needed without risk of corruption or deletion. Compliance is easy to demonstrate, and end users can have read only access to search and retrieve email themselves at any time from any device.
My data is protected by Microsoft in their data centers. I didn’t think I would need to provide backup and recovery services anymore. What has changed?
More often than not, data is deleted only to later realize that it is still needed. While it is possible to recover deleted items from within Exchange Online and OneDrive for Business, the retention for these items is often inadequate. By using Barracuda’s Cloud-to-Cloud Backup for Office 365, you can eliminate the risk of items lost due to accidental deletion, as well as retain emails and files indefinitely if users were to leave your organization, all without having to purchase additional licenses. Additionally, you can delete inactive user accounts, freeing up additional Office 365 user licenses.
Why is advanced threat protection important for Office 365 users?
Basic built-in Office 365 email protection focuses on spam and viruses; it can’t detect or stop zero-day attacks, phishing attempts, and sophisticated malware threats. Barracuda Essentials uses the Cloud to place a protective barrier and secure “sandboxes” between the user’s Office 365 environment and any email attachment or link that is deemed to be suspicious.
How does Barracuda Essentials protect organizations from spear phishing and BEC?
Spear phishing attacks are highly personalized, and typically very low volume with no malicious attachments or links inside. Because of this, they are very hard to stop with existing email security solutions. As a complement to the Barracuda Essentials, Barracuda Sentinel is the leading comprehensive AI solution for real-time spear phishing and cyber fraud defense. Delivered as a cloud service, Barracuda Sentinel combines a powerful artificial intelligence engine, domain fraud visibility using DMARC, and anti-fraud training into a comprehensive solution that protects people, businesses, and brands from spear phishing, impersonation attempts, business email compromise (BEC), and cyber fraud.
