E-Mail Compliance

Postini helps assure inbound and outbound content policy compliance concerning offensive language, preventing employees from sending proprietary content outside the organization, and prohibiting employees from using email for illegal and inappropriate purposes. Postini supports encrypted email transmission, helps monitor employee communications, and preserves network bandwidth by limiting the size and type of attachments that are accepted.

Attachment Filtering

While inbound attachment management reduces the resources required to process unwanted attachments (such as large MP3 music files), outbound attachment filtering can be used to prevent sensitive or confidential file types from leaving the enterprise.

Content Filtering

Postini’s email security managed service provides both inbound and outbound email policy enforcement capabilities. Outbound email filtering by Postini enables organizations to scan outbound messages for viruses and apply content policies, protecting both customers and partners and ensuring that corporate policies regarding appropriate use are observed. Inbound anti-virus scanning prevents viruses from entering a corporate network through the gateway. Outbound anti-virus scanning prevents the spread of viruses to customers and partners. Outbound content filtering also prevents confidential or sensitive data from leaving the enterprise network and entering the hands of competitors.

Legal & Regulatory

Postini's outbound email functionality enables the administrator to automatically block, reroute or copy email matching certain criteria. For example, the enterprise can retain copies of all mail sent by professionals covered by industry regulations, or containing key phrases. To meet regulatory requirements that require retention of all email communications, Postini also offers a “compliance switch” to assure that any quarantined emails cannot be read by the user unless they are first accepted by the user into the customer's archiving system. Because Postini does not use a “store and forward” approach typical of other service providers, its patented pass-through process eliminates any performance penalty or security and privacy concerns.

Encryption Support

Postini supports secure email transmissions based on the TLS encryption standard, and is the world’s largest encrypted email network. Encrypted emails processed by Postini still pass through its managed service data centers and are automatically scanned to block spam, viruses, and enforce content policy and compliance. Thus, Postini is able to support encrypted email transmission over the Internet while preserving the ability to filter out unwanted or malicious messages and prevent email content policy violations.
