Once message are tested, you can define the action you want taken including logging, modify subject header, add header, redirection to reject email and BCC.
ePrism employs a number of technologies to scan and filter email content and assure that your acceptable use and security policies are being enforced:
Advanced Content Scanning – ePrism offers deep scanning of email attachments to prevent private and confidential files from leaving your company. This includes scanning attachments such as PDFs, Word
documents and hundreds of other file types.
Expanded Filtering Options – Several actions allow you to create filter rules that encrypt, quarantine, BCC, notify, redirect or discard messages.
Dictionaries – ePrism offers custom dictionary support for content filtering allowing you to easily match simple words and phrases against message and attachment content.
Policy Integration – Content filtering is integrated with ePrism’s policy engine allowing you to create different sets of filter rules for different users, groups and domains.
ePrism includes Kaspersky Labs Antivirus®, winner of the coveted Best Anti Virus Solution award from SC Magazine. Automatic hourly updates to this virus-scanning engine ensure that the latest viruses are being identified and eradicated before they reach your host.
Malformed messages can allow hackers to avoid detection, crash your systems and lock up your mail servers. ePrism allows only correctly formatted messages to reach their destination.
ePrism’s fail-safe clustering architecture for high availability (HALO) means your email is never lost due to individual system failure. ePrism’s HALO provides security, cluster management, load balancing and “stateful failover” queue replication capabilities that guarantee consistency during a crisis. See the HALO for ePrism Enterprise datasheet for a more in-depth discussion of these features.
