Mangosoft to Demonstrate Mangomind Secure, Collaborative Virtual Office at RSA Conference 2002

Mangosoft to launch Mangomind 3.0 online multi-user database sharing; preview encrypted email messaging and support for PocketPC devices

Westborough, MA - February 12, 2002: Mangosoft Inc. (OTC: BB: MGOF), a developer of Internet enabling business software solutions, today announced that it will demonstrate extended collaboration features for its Mangomind^SM Business Internet File Service^SM at the RSA Conference 2002, San Jose, CA, February 18 - 21, 2002. Mangosoft will demonstrate these innovations in the RSA (NASDAQ: RSAS) Secured Partner Pavilion, Booth #726.

Mangomind is a software solution that creates a secure virtual office where geographically dispersed workgroups can access information from a central location, from anywhere at anytime, and collaborate privately with remote team members. The service uses RSA's BSAFE (R) 128-bit encryption technology to create a client-to-client secure channel offering remote document access, multi-user file sharing, online file storage, offline access to files, and secure messaging. Mangomind's end-to-end encryption secures files both in transit over the Internet and in storage on our servers - only authenticated users hold the keys to decrypt their files. All of these technologies are seamlessly integrated with Microsoft Windows, delivering the ultimate in ease of use.

At the RSA Conference, Mangosoft will demonstrate several innovations that extend the collaborative capabilities of the Mangomind secure virtual office:

Database file sharing - Mangosoft will launch Mangomind 3.0 and demonstrate the ability to share client databases with multiple users while online. This new feature extends collaborative capabilities from Microsoft Office documents to Windows databases and database driven applications, including popular accounting software packages, contact management packages, and calendars.

Encrypted email - Mangosoft will preview the seamless integration of Microsoft Outlook with Mangomind's security architecture. This simplifies secure workgroup email by eliminating the need to manage email-specific encryption keys. By making security easy, this technology helps workgroups protect their communications.

PocketPC support - Mangosoft will preview support for the Microsoft PocketPC platform and thus extend access to the Mangomind virtual office to users of handheld, wireless devices. Mangomind's secure virtual office approach overcomes wireless security issues in a protocol independent way.

"These new innovations emphasize Mangosoft's continuing commitment to seamlessly integrated, easy to use tools for today's collaborative business world," said Scott Davis, vice president and chief technology officer, of Mangosoft. "Through the Mangomind virtual office, business people can securely communicate and collaborate with others on demand and with the programs they already know and use everyday; as easily as if everyone were working in the same office. Mangomind is the simplest, most flexible inter-company collaboration tool available for the Microsoft Windows environment."
