Sendmail has updated its Sentrion messaging security appliance to protect outbound email.

Sentrion Message Processor is designed to stop inbound threats as well as ensure that outbound messages adhere to comply with policies, without affecting performance, according to the company.

With the new outbound data leak prevention features, organisations can monitor the content sent out via email to ensure that federal or industry regulations and corporate policies are being met, officials said.

Sentrion's inbound features include spam and virus protection, connection control that throttles back messages deemed suspect, policy implementation designed to keep communications in line with regulations and corporate mandates, and the archiving and encrypting of messages, according to officials.

All of these features can be administered from a web interface.

The Sentrion Message Processor starts at $25,000.
