Following a 1000-user trial, the Australian Taxation Office will deploy e-mail and document classification software to 27,000 employees throughout 2007.
The message classification software, from Canadian company Titus Labs, will be used to securely categorize and classify taxpayer's e-mail so it can be managed more effectively.
The ATO conducted a pilot of the software with 1000 users, which will be deployed to some 27,000 employee desktops next year.
The Australian Government Information Management Office (AGIMO) guidelines and Defence Signals Directorate (DSD) policies have endorsed e-mail classification by mandating that all government departments introduce "e-mail marking" by March 2007.
The Titus Labs' software allows organizations to manage and control sensitive e-mail messages via defined policies.
The professional edition can be configured to force all ATO employees to specify the classification level of each e-mail they send via Microsoft Outlook and Outlook Web Access. The classification is enabled via a drop down menu on the Outlook toolbar.
Titus Labs' president Tim Upton said today's enterprises need to securely classify email without changing the way they do business.
"Our ability to provide a simple and easy-to-deploy classification and archival solution for email and documents provides immediate results for the protection of sensitive information," Upton said.
Selected classifications enable additional security-related policies to be applied automatically based on an administrator-defined central policy. The classification label is then embedded in the e-mail's header and subject line.
Other government departments using Titus Labs' software include the Department of Transport and Regional Services, the Department of Environment and Heritage, and the Prime Minister's office.
