Alternative to Barracuda Email Encryption

Emails often contain sensitive and proprietary information. As such, they are a target for cybercriminals intent on using it to extract this data. Also, emails are prone to accidental data exposure. Research has shown that 83% of data breaches start with an email. Another study found that 93% of organizations experienced a data breach caused by a compromised outbound email. Whatever the cause of an email-initiated breach, encrypting emails can prevent accidents and malicious attacks.

There are many methods and solutions available to encrypt emails. Here, TitanHQ explores Barracuda Email Encryption and compares its features and pricing with TitanHQ EncryptTitan.

What is Email Encryption, and Why is it Important?

Email is a communication channel that is going nowhere. Despite instant messaging and social media, email use continues to climb. The number of emails sent and received daily is expected to increase to 392.5 billion by 2025.

Email is the primary method of communicating inside and outside a business. The volume of emails and the data type in this communication channel make email vulnerable to attack and accidental data exposure. Hackers target both sensitive company data and personal data. They can use the latter to commit fraud, steal ID, and phish employees.

Accidental data exposure is the other side of the email vulnerability coin. For example, a Denmark data protection authority study found that the most common GDPR breach was caused by the correct information going to the wrong recipient.

Email encryption prevents email-borne data from being exposed accidentally or through a malicious attack. Encryption software changes the email content and any attachments from plain text to ciphertext, rendering them unreadable to anyone other than the intended, authenticated recipient.

Core Features of Email Encryption

Not all email encryption solutions are the same, but certain core features are fundamental to the effectiveness of the encryption.

Cloud-Based SaaS

Modern email encryption solutions should be cloud-based. This ensures scalability and ease of deployment and management. Cloud-based email encryption solutions provide a centralized console to allow administrators to configure security rules and manage the service.

End-to-End Encryption (During Email Transit)

End-to-end encryption (E2EE) is a fundamental feature of email encryption. Emails are encrypted on the sender's device and then decrypted when opened by an authenticated recipient—emails are protected during transmission. Public key encryption (or asymmetric encryption) is used to perform the encryption. Internet protocols, like TLS (Transport Layer Security), underpin the secure transfer of encrypted messages. Emails and any attachments should be encrypted while stored, for example, in an email archive.

Easy to Use to Reduce Human Error

Email encryption must be easy to ensure that human error, like forgetting to encrypt an email, doesn't happen. An option that some email encryption solutions offer is deep integration with email clients, like Outlook 365. For example, an Outlook 365 plug-in makes email encryption easy by providing a click-to-send encrypted button.

Data Leak (Loss) Prevention (DLP)

Some email encryption solutions, like EncryptTitan, provide DLP capability. Data leak prevention or data loss prevention (DLP) enforces security controls to protect data from being leaked, corrupted, damaged, deleted, stolen, or corrupted. Administrators apply protection policies, triggered using rules, to control data as it is shared via email. The rules are typically defined using keywords and attachment type and should be granular enough to control data leaks based on contacts and domains.

Access and Authorization of Recipients

Encryption should not prevent ease of communication. Therefore, an email encryption solution must make receiving encrypted emails straightforward while maintaining security. Email encryption solutions use several methods to ease the recipient's access to encrypted emails. Examples include using web portals to hold the emails, encrypted PDF versions of the emails, or S/MIME, which layers authentication atop the encrypted email to control access.

At a Glance: Barracuda Email Encryption vs TitanHQ's EncryptTitan

Capterra Review

Features of Barracuda Email Encryption

Barracuda email encryption is included in Barracuda Essentials. It is a cloud-based solution. However, an encryption appliance (hardware) version is available for companies that wish to use hardware encryption.

The Email Encryption Provided by Barracuda Includes the Following Core Features:

Email Encryption

Barracuda email encryption secures email by using E2EE encryption. Messages are sent via the Barracuda Message Center. Recipients can securely retrieve a message by navigating the portal and entering a password. Transport Layer Security (TLS) and AES 256-bit encryption are used for message encryption during transit and at rest. Manual and automated encryption via policies is offered.

Data Loss Prevention (DLP)

Barracuda DLP is applied to outbound emails to ensure sensitive data only leaves an organization if authorized. The outbound email filtering used by Barracuda also blocks outbound spam and viruses. By ensuring outbound emails are spam-free and not infected by viruses, the company mail server IP addresses and domains will not be added to spam-block lists. DLP options allow administrators to create and enforce content policies that are then used to stop sensitive data from leaving the company network via email. Policies are used to automatically encrypt, quarantine, or block outbound emails that trigger a content policy rule.

Features of TitanHQ EncryptTitan

TitanHQ EncryptTitan is a cloud-based email encryption solution ideal for delivery via an MSP. Deployment, management, and configuration are all performed centrally to enforce encryption and mitigate human error.

Email Encryption

EncryptTitan uses E2EE to protect emails from sender to receiver and store them in storage during the email lifecycle. EncryptTitan uses Transport Layer Security (TLS) and AES 256-bit encryption to secure messages during transit and at rest. Manual and automated encryption via policies is deployed to provide use case-appropriate activation of email encryption - automation occurs when policy rules are triggered, e.g., by certain keywords. Recipients of encrypted emails have three choices when opening an encrypted email:

TLS Verify: TLS Verify meets state and federal requirements for sending private information over email. This method is seamless as it does not require the recipient to take additional steps to view the email. If the recipient's web server supports TLS 1.2 or 1.3, the message will be decrypted by the web server. This method is an option; additional authentication can be enforced if a Compliance or IT Officer requires it. If TLS is not supported, EncryptTitan defaults to the next available delivery method.

Easy Secure: Easy Secure is a passwordless delivery method. Easy-Secure messages are stored on a secure portal utilizing "data-at-rest encryption." Easy Secure can be configured to allow secure messages to be opened with a click of the unique message link or by requiring the unique link and a time-based one-time passcode (TOTP) that can be delivered over email, SMS, or OTOP.

Secure Portal: The Secure Portal delivery method stores emails on a secure portal. An encrypted email recipient is prompted to log in to the Secure Portal and enter a username and password to access the email. Multi-factor authentication (MFA) can be used to add layers of security as needed. Encrypted message recipients can reply securely to the sender of an encrypted message directly from the Secure Portal. The Secure Portal supports message auditing, read receipts, and message recall.
