Software-as-a-service security provider Proofpoint has launched an updated version of its Enterprise email security and privacy platform, designed to improve spam and data loss prevention while supporting growing compliance requirements.
Version 6.2 of Proofpoint Enterprise can identify and temporarily quarantine suspected spam for an administrator-configurable period of time or until a specific number of spam updates have been received.
There is also support for Domain Keys Identified Mail, a system designed to verify sending domains and therefore identify and stop phishing attacks, blended threats and other malicious emails, the firm said.
"Reputation is no longer enough to stop spam as there has been a huge increase in the number of highly targeted attacks," said Proofpoint's European marketing director Paul Hennin.
"You can't underplay the importance of an effective anti-spam solution in the enterprise, especially with the sophisticated blended threats we're seeing which are increasingly hard to deal with."
The Smart Send feature allows administrators to create policies notifying an email sender if an outbound message is violating a particular policy.
The sender can then review and change the message, remediating the problem themselves and removing the burden from the administrator.
Finally, a new Outlook plug-in allows users to encrypt and decrypt messages on demand, and messages can also be sent via Transport Layer Security encryption when available.
A BlackBerry plug-in brings the same functionality to the mobile workforce, according to Hennin.
The product is available as a physical or virtual appliance, or on a software-as-a-service model.
