Diversinet to Join Sandisk's Enterprise Solutions Technology Alliance
Will Work on Compatibility and Interoperability of Diversinet MobiSecure Security Solutions with
SanDisk Secure Portable Devices

TORONTO, Canada, September 24, 2007 – Building upon its technology alliance with SanDisk®, Diversinet Corp. (OTCBB: DVNTF), a leading provider of wireless data application and security infrastructure products and services, today announced it will join the SanDisk Enterprise Solutions Technology Alliance (SESTA).  SESTA gives members the opportunity to test the compatibility of their products with secure portable solutions from SanDisk, a leader in personal storage devices.

“Diversinet is a welcome addition to the distinguished roster of SESTA members,” said Ella Taran Katz, senior manager for business development in the Enterprise Division at SanDisk.  “Enterprise IT managers will have a new level of comfort in knowing that Diversinet and SanDisk products work together without having to worry about conflicts or incompatibilities.”

“One of the greatest IT security threats facing businesses today is the proliferation of inexpensive, uncontrolled and highly portable storage devices,” said Stuart Vaeth, chief security officer for Diversinet.  “Our MobiSecure one-time-password soft token and provisioning technologies, combined with SanDisk’s secure devices, will offer an effective solution for protecting corporate data.”

SanDisk’s flagship secure device is the Cruzer Enterprise high-speed USB flash drive with mandatory password protection and 256-bit AES hardware-based encryption.  Data stored on Cruzer Enterprise has virtually ironclad protection against access by unauthorized users if the drive is lost or stolen.  Diversinet intends to offer its MobiSecure soft token technology for SanDisk Cruzer USB flash drives in the future.  More information on Cruzer Enterprise and SESTA is available online (www.sandisk.com/sesta).

MobiSecure strong authentication products are fully automated, conform to industry standards and are designed to be easy to deploy and use for high-volume Internet or wireless based user identity security. MobiSecure one-time-password soft tokens operate on mobile phones or personal computers and can also be embedded into microchip or smart card technologies.
