Metascan 3.9.4 is Now Ready for Download

This month's Metascan® release, 3.9.4, is now available on the OPSWAT Portal! This release includes enhancements to the Metascan Mail Agent, more efficient hash calculating, as well as other fixes and enhancements.

After enabling the Mail Agent that comes with all Metascan licenses, administrators can now use the quarantine feature and alert both the initial sender and intended recipient if their message needed to be quarantined. This function improves both internal and external communications, as both the recipient and the sender may need feedback regarding the delivery of their message. Without this function, time-sensitive messages may not be delivered in a timely fashion, and alerting both sides of a quarantined email allows for them to seek other communication channels if needed.

The quarantine of files, such as those received through email, can have numerous benefits. File quarantine can help you identify the source of a threat by performing an analysis of the file as well as removing the risk of losing valuable data from improperly classifying a clean file.

The white paper covers the three main aspects to consider when configuring and maintaining a file quarantine, and the security benefits of implementing a quarantine within your security architecture.
