"With so many breaches and costly data loss incidents in the news, it's hard to believe that any business would fail to take such a basic precaution as to encrypt sensitive traffic as it's transmitted to or from a website," said Michael J.

Google continues enterprise push with Data Loss Prevention for Gmail

Google on Wednesday released a new tool for companies that want to make sure their sensitive information isn't shared via email.Gmail for Work now has Data Loss Prevention (DLP) capabilities, which allow administrators to set policies about what information users can send through Gmail. The goal is to protect confidential records and make sure users don't accidentally leak key data. For example, a policy could prohibit members of the accounting team from sending any emails with a spreadsheet attached. Policies could also be used to quarantine messages until an administrator can review them, or modify them to remind users not to share confidential information outside of the company.
