XML Proxies
Key Findings: XML Proxies are hardware or software solutions that actively listen for XML traffic on the network and either pass it along unmodified or perform some action on the XML content. XML Proxies can operate transparently as an XML “gateway” or as auxiliary applications on the network. ZapThink estimates that XML represents less than 2% of all traffic on the enterprise network in 2002; however, this percentage is expected to increase to almost 25% of all LAN network traffic by 2006. Current firewall and proxy solutions are inadequate to handle XML traffic. Instead of being simply network protocol-aware, XML Proxies are XML-aware. XML Proxies are capable of examining traffic at the content level, and can optionally handle other message types such as HTML or EDI. XML Proxies will converge on a single set of functionality for handling corporate-wide XML security, management, routing, transformation, and performance enhancement. As XML Proxy…

ZapNote: Vordel
Of all the different types of XML Proxies, the software XML firewall is one of the simplest to understand. It intercepts incoming XML messages, validates them, determines whether they are properly authorized, and routes them accordingly. Vordel’s VordelSecure product is a software XML firewall that runs on a Web server, therefore leveraging the capabilities of the Web server to provide high-performance security protection to the enterprise. Furthermore, VordelSecure supports a wide range of open standards and specifications and interoperates with many popular Web Services platforms, making it a likely choice for many enterprises looking to protect their Web Services from unauthorized or malicious traffic.[hide -1]Download File[/hide][hide +0]Register to Access this Document[/hide]…

ZapNote: Forum Systems
Rather than requiring each application on the network to comply with the latest XML-based security specifications, compression algorithms, and business process standards, most organizations will seek to implement centralized intermediaries that will handle these tasks on behalf of the applications. Hardware XML Network Appliances can fill the role of the XML and Web Services intermediary in a credible way. Forum Systems has produced a hardware appliance that aims to fill the role as Web Services Proxy as and XML "Application Firewall" by processing XML network traffic and applying security, routing, and transformation operations to the data in a transparent manner. They see the XML Network Appliance as an increasingly important device that will become crucial to the acceptance and growth of XML use within the enterprise. Forum has correctly reasoned that security is the primary and most immediate market for these XML Network Appliances.[hide -2]Download File[/hide][hide +1]…

ZapNote: Westbridge Technology
Many software vendors entering the Web Services arena are jostling each other with respect to their various business models. Are they a Web Services infrastructure platform or a Web Services security platform? Or maybe they are a Web Services management platform, or even a Web Services gateway or router? While most vendors focus on one core competency, Westbridge Technology is developing a product that will be all of these things. The Westbridge Technology XML Message Server is fundamentally a Web Services management platform. However, it also offers security features, message transformation and routing, as well as directory administration, all on top of a powerful policy engine. If Westbridge can execute on their vision, they will be a solid contender for the elusive enterprise IT dollar, although they have set the bar quite high.[hide -2]Download File[/hide][hide +1]Purchase: $395[/hide]…
