Mangomind Service Relies on RSA BSAFE Crypto-C to Enable Enterprises to More Securely Engage in Business Over the Internet

Bedford, MA - October 16, 2000: RSA Security Inc. (NASDAQ: RSAS), the most trusted name in e-security, today announced that Mangosoft Inc. (OTC Bulletin Board: MGOF), developers of Internet business software products and services, has licensed RSA (R) Crypto-C software for its Mangomind (Multi-user InterNet Drive) ^SM. By selecting RSA Security's software, Mangosoft is able to allow multiple users to more securely transmit, share and store files via its Mangomind service. Each Mangomind service user is authenticated using private key encryption, and all files stored on the Mangomind drive are transmitted over the Internet and protected with 128-bit encryption.

A key requirement of our Mangomind file sharing service is the ability to securely transmit and store mission-critical business information over the Internet, said Bob Primmer, vice president of marketing at Mangosoft. Mangosoft chose RSA Security because it is recognized as the most trusted name in e-security, and as such, we are able to assure our customers that the service is protected by state-of-the-art security software.

As more enterprises continue to move critical business processes to the Internet, security is clearly becoming an important business consideration, said Scott Schnell, senior vice president of marketing at RSA Security. We are pleased to welcome Mangosoft as an RSA Security software customer, and look forward to working with them as they help companies enter the Internet arena.

The RSA (R) line of security software is embedded in today's most successful Internet applications, including Web browsers, wireless devices, commerce servers, e-mail systems and virtual private network products. Built to provide implementations of standards such as SSL, SMIME, WTLS, IPSec and PKCS, RSA BSAFE products can save developers time and risk in their development schedules.
