CYREN (formerly Commtouch Software) is no fan of spam. The company provides e-mail filtering and management applications that help administrators reduce the flood of unsolicited messages (spam) on their networks. Its application uses proprietary algorithms and software hosted at CYREN's data centers to filter spam from legitimate messages. The company's Recurrent Pattern Detection (RPD) technology constantly searches the Internet identifying spam by volume and speed of distribution. CYREN markets its technology in the form of a software development kit (SDK) that it sells to equipment makers.
