Quest InTrust Enhances Compliance Capabilities with Plug-in for Exchange Server

ALISO VIEJO, Calif. -- The importance of e-mail as most organizations' primary communications tool translates into a critical need to protect it from both external and internal threats. Quest Software, Inc. (Nasdaq:QSFT) today announced the availability of the Quest InTrust Plug-in for Exchange, the first product on the market to allow real-time tracking of detailed mailbox owner and non-owner access and activity, as well as auditing of changes to permissions and configurations in Exchange Server environments.

For example, in many organizations, employees have access to other employees' e-mail, such as an administrative assistant who checks the e-mail of a company executive. Until today, no one has had the ability to track what the assistant was doing as a delegate to the mailbox. This new capability allows organizations to take immediate action before confidential information is compromised.

"Like most companies today, e-mail is a critical tool for our business," said Adam Kimball, IT director, ThyssenKrupp Elevator. "Therefore, it's imperative that we are proactive in examining options that make sure this tool remains secure and compliant. We presently utilize Quest's products to assist in managing our e-mail environment and we are considering the Quest InTrust product to further establish the security of this environment."

The core product, Quest InTrust, improves compliance and security by collecting, storing, reporting and alerting on heterogeneous event log data. The new Plug-in for Exchange extends the value of InTrust by providing detailed auditing of changes to Exchange Server configurations and permissions, as well as recording all unusual owner and non-owner access activity. The new plug-in also gives organizations the ability to analyze and alert on information such as which e-mails are read, deleted and copied, and by whom. The InTrust Plug-in for Exchange adds to Quest's Exchange compliance offering, which includes products for archiving, reporting and analysis, and synchronization of Active Directory and Exchange data.

"Business-critical information is sent via e-mail every day, and when misdirected, that information could potentially harm an organization," said Jackson Shaw, senior director, product management, Quest Software. "We can now help customers prevent this type of problem, and also help them meet compliance requirements so that business will not be interrupted."

Version 1.0 of Quest InTrust Plug-in for Exchange is available now, with North American pricing beginning at $20 per enabled user mailbox (USD).
