Proofpoint has introduced its next-generation Software-as-a-Service (SaaS) and appliance email security and data loss prevention platform.

Proofpoint 6 includes the company's policy-based email encryption solution, data loss prevention security and workflow enhancements. There is also support for DomainKeys Identified Mail (DKIM) and email authentication.

The company claimed that the platform's features are powered by the new Proofpoint Encryption module and Proofpoint Hosted Key Service, part of the Proofpoint Enterprise privacy suite.

Peter Galvin, chief marketing officer for Proofpoint, said: “To fully protect private data in email, enterprises require not just the means to accurately detect confidential information and prevent data leaks, but also the ability to automatically encrypt sensitive content.

“Proofpoint's policy-based encryption features protect the security and integrity of private data in email, ensure compliance with financial and healthcare privacy regulations and help organisations avoid costly data breach notification and remediation events.”
