Reactivity, Inc., announced it has entered the enterprise RSS market, announcing that its Reactivity Gateways are able to make XML-based syndication practical for use with sensitive, secure and private content. Reactivity Gateways provide the security and other features enterprises need to take RSS beyond public news, marketing and product announcements, while ensuring that RSS use complies with the privacy and data protection requirements of government and corporate regulations. Reactivity Gateways can be used to authenticate access, secure transport, encrypt single and aggregated RSS feeds and transform RSS data to and from other XML formats. Advanced tracking, alerting, reporting and XML message manipulation capabilities, made possible by Reactivity’s Advanced Messaging Architecture, simplify the compliant use of RSS while enabling enterprises to respond proactively to non-compliant RSS situations and improper identity usage. And Reactivity’s any-to-any interoperability and mediation with other XML and Web services formats, standards, transports and data allows integration of RSS with existing back-end systems.
