Smartcrypt for Email

Retain control of sensitive data after it leaves your network

Email is an inherently insecure form of communication, yet it remains the most common form of business communication. Though few email users give it a thought, email messages typically pass through several unsecured systems on the way from sender to recipient, creating multiple opportunities for sensitive information to be compromised in the process.

A smarter way to secure your email

Unlike other email encryption products, Smartcrypt provides persistent data-level encryption for email attachments as well as for the message text itself. This means that documents, spreadsheets, and other sensitive files remain safe from unauthorized access, even when saved to a message recipient's computer or shared in the cloud.

Smartcrypt also integrates with existing data loss prevention solutions, allowing DLP scanners to decrypt and inspect message contents before they leave the organization's network. Thanks to PKWARE's industry-leading data compression technology, messages are smaller after the encryption process, reducing network resource demands.

PKWARE's Smartkey technology automates key management, eliminating the complexity of key creation, exchange, and synchronization. With Smartcrypt, administrators can grant or revoke access to encrypted data at any time, even after it has been shared outside the organization.

How it works

Smartcrypt integrates with Microsoft Outlook to provide an automated workflow for encrypting and decrypting emails.

  • Administrators use the Smartcrypt Enterprise Manager to create data protection policies and define the organization's criteria for sensitive information.
  • Smartcrypt agents on employee laptops and desktops integrate with Microsoft Outlook and scan email messages as they are created.
  • If an email message or attachment contains data that fits the organization's definition of sensitive information, Smartcrypt automatically applies persistent encryption using a pre-defined encryption key. No action is needed on the sender's part.
  • Authorized recipients can decrypt and read the encrypted message using Outlook's integration with Smartcrypt, or by using the free Smartcrypt Reader
  • If the message is forwarded to other, unauthorized recipients, those users will not be able to access the encrypted information

Users can also choose to encrypt outgoing messages (and select encryption keys) using a manual process, if this option is enabled by the organization's administrators.

Email encryption that doesn't break DLP

Smartcrypt can be integrated with existing data loss prevention workflows. Smartcrypt includes company-controlled keys in each encryption operation, enabling DLP scanners to decrypt content that has been encrypted elsewhere in the organization. Smartcrypt also allows the organization to encrypt data that was not protected prior to sending, eliminating the need to block transmissions that contain sensitive information.

With a single encryption standard across the organization, DLP processes become more effective and your organization's sensitive information is more secure.

The Smartcrypt for Files and Folders agent is installed on laptops, desktops, tablets, and mobile devices of users who may potentially send or receive sensitive information via email.

Enterprise-ready deployment options are available for large-scale implementations.

Agents can be configured to encrypt all emails, to prompt users before encrypting, or to use Smartcrypt’s data discovery capabilities to scan and encrypt messages based on their contents.


Administrators use the Smartcrypt Enterprise Manager console to define encryption policies for departments, teams, or individual users.

Encryption policies govern which options are available to users and which encryption keys are used to protect their documents.

Smartcrypt’s innovative Smartkey technology lets administrators grant or revoke access to encrypted information at any time.

End User Experience

There is no change to the process of composing emails or selecting attachments.

Before a message is sent, Smartcrypt compresses and encrypts outgoing emails in accordance with organizational policies. Users may be prompted to select an encryption key for each message, or a key can be designated for use by default.

When Smartcrypt Data Discovery is enabled, the Smartcrypt agent automatically identifies and encrypts sensitive data based on the organization's policies.


Smartcrypt delivers a wide range of benefits, making your organization's sensitive data more secure and easier to manage.
  • Protects sensitive information
  • Integrates into existing workflows
  • Enables organization-wide control
  • Simplifies key management
  • Reduces data volumes
