Mobile phone operator O2 has deployed rights management software to protect confidential documents and e-mails sent by board executives and other senior managers handling sensitive financial and business information.
The company deployed the system, which is now being extended to cover Blackberry users, as part of a programme to reduce the risk of sensitive information, which could have a material effect on the company, falling into the wrong hands.
The rights management technology, from software supplier Stellent, allows O2 to control which users have access to confidential documents and e-mails once they have left the company.
"Information is one of the company's greatest assets and security of those assets should by a priority," said Mark Sheircliff, group head of information security.
Under the system, encryption travels with the document, allowing O2 to control whether information can be forwarded to other people or printed out.
"All information in 'strictest confidence at board level' is encrypted, both current and historic. If the document is on a memory stick or hard drive, or an e-mail inbox at home, it is still encrypted," said Sheircliff.
O2 introduced the system after realising that its existing policy to encrypt confidential documents was not being properly enforced because staff lacked the tools.
The company chose the Stellent platform after evaluating five alternative systems. The system took three months to deploy.
