The company will roll out group-wide mail encryption by the end of the first quarter this year, said Robert Ife, VP of global risk management at Aon. "We are using TLS between mail gateways rather than leaving it up to the users. Users won't bother or will forget: we want it completely transparent."
Ife faces the challenges of clients unable to support encryption, and of global policy consistency. For example, Aon's US business uses MessageLabs for email security.
