Your browser identified itself as a version of IE that was often shipped with default settings that were less than secure. Your internet experience could be made more secure by opening Internet Options in your browser, going to the Advanced tab and looking under the security settings for "Use TLS 1.1" and "Use TLS 1.2". Ensure these are turned on (checked). Doing so will enable your browser to support a higher quality of encryption on this and other websites. You will still be able to browse this site without turning on support for TLS 1.1 and 1.2, but we will have to use a lower level of encryption to accomodate you. See this question on Stack Exchange's Superuser forum from 2011 for more details keeping in mind the comments about TLS 1.2 non-support were made many years ago, and things have changed since then.

If the support for better cryptography has been turned on for your browser, thank you, and you can safely ignore this advisory.

Smartcrypt for Email

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 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 if they are 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 provides a streamlined, intuitive workflow for encrypting and decrypting emails. The Smartcrypt Outlook add-in encrypts and compresses outgoing messages with a minimum of user involvement. Authorized message recipients can then use Smartcrypt or PKWARE’s free ZIP Reader to decrypt and open encrypted messages. Encrypted files cannot be read by unauthorized users, even when they are copied or saved outside the organization's network.

Smartcrypt can be integrated with existing data loss prevention workflows, allowing DLP scanners to access and evaluate encrypted emails. With a single encryption standard across the organization, DLP processes become more effective and your organization's sensitive information is more secure.

Organizations can use Smartcrypt’s data discovery capabilities to make email encryption easier and more secure. When discovery is enabled, Smartcrypt scans each outgoing message (body and attachments), and encrypts messages containing sensitive data based on the organization’s security policies.

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.
