Cellcrypt has introduced a secure conference service that provides both device authentication and voice call encryption to smartphone users.

Cellcrypt claimed that traditional conference calling services are open to abuse through unauthorised access and often poorly managed with dial-in details and PINs seldom changing, with some participants often accessing conference calls using mobile phones, which are increasingly at risk of interception. The Cellcrypt Secure Conference Service authenticates the participant's mobile phone and encrypts conversations end-to-end between each participant and the conference bridge.

The participants select a bridge number from their Cellcrypt Mobile-enabled BlackBerry or Nokia smartphone to enter the call. Office phones can also securely participate in conference calls when connected via Cellcrypt's Enterprise Gateway solution.

Simon Bransfield-Garth, CEO at Cellcrypt, said: “Conference calls by their very nature typically contain some of the most sensitive and confidential information an organisation has. These calls are highly desirable to attackers, who know just how valuable the information is.

“As the risk of cellular interception has increased so has the vulnerability of mobile executives accessing conference calls from the mobile phones. Organisations should urgently review their communications practices and act to protect their mission-critical conference calls.”
