Protect Your Customers and Yourself by Encrypting Sensitive Email


Netgain Networks and Zix Corporation have partnered to provide email encryption as a hosted service. Now you can easily ensure privacy and meet regulatory compliance requirements with cost-effective email encryption.


With an increase in regulatory pressures, identity theft and highly-publicized security breaches, companies that do not encrypt emails containing sensitive information are at risk of regulatory fines, lawsuits, negative PR and a loss of intellectual property.

Companies dependent on building a relationship of trust with their customers and business partners cannot afford to risk such potential damages to their brand images. Email encryption is an important piece of the security puzzle; it protects your company, your customers and your business partners. The question becomes how to implement this critical business process.

With ZixDirectory, customers eliminate the need to build their own directory of encryption keys and instead leverage ZixCorp’s hosted and shared security network, which includes:

  • US federal banking regulators and the SEC
  • More than 1200 financial institutions
  • 20 state banking regulators
  • More than 1,000 US hospitals

This email encryption service offers the ability for a company to encrypt outbound emails based on content, sender and recipient.

The full content scanning of messages and attachments enables companies to comply with industry regulations, thanks to managed lexicons that automatically encrypt, reroute or block email messages containing financial (GLBA), healthcare (HIPAA) and profane content. A company’s sender can also trigger a particular message to be encrypted, as well as encrypting all emails destined for specific recipient email domains and addresses.
