Email has become a vital business tool, so much so that analysts estimate as much as 80 percent of a company's intellectual property is contained in its email. But since email is transmitted as clear text over the Internet it is susceptible to compromise by network "sniffers" that monitor traffic for confidential, and ultimately profitable, information. A natural desire to protect this increasing amount of sensitive email-based information is fueling growth in email encryption, as is the need to meet legal requirements to comply with government privacy regulations, particularly in healthcare, financial and government services. To maximize protection, the encryption solution should minimize barriers to use.Trend Micro Email Encryption efficiently secures email delivered to anyone with an email address. It enables organizations to deliver information securely and helps comply with regulations. Trend Micro's Private Post technology, developed by cryptographers at the University of Bristol, uses identity-based encryption (IBE) to address the limitations of earlier Public Key Infrastructure (PKI) technology, eliminating burdensome pre-registration and certificate management. Encrypted content is pushed from senders to recipients like any other email. Trend Micro Email Encryption Client is software plug-in for popular email clients that deploys without modifying existing business processes and integrates seamlessly with the existing email infrastructure.
