Edge Security for Multi-Enterprise Data Exchanges using IBM Sterling Secure Proxy

Edge Security!!


As global business becomes more and more interconnected, traditional organization boundaries are being redefined and the exchange of data across these boundaries is increasing rapidly. With such openness being created, a malicious “denial-of-service” (or) “man-in-the-middle” attack could cause terrible damage to your organization and in turn erode the trust of your partner network. We’ve found in our experience that internal networks and legacy systems are more than often vulnerable due to insufficient file transfer security measures.

IBM Sterling Secure Proxy


IBM Sterling Secure Proxy is an application-based proxy that protects your internal network from malicious attacks that may negatively impact your business processes, both internally and externally with your trading partners. With IBM SSP, partner connections are intercepted at the edge and once authenticated are transparently redirected to trusted connections within your enterprise.

Nowadays security experts are turning to Proxy Server based approaches to ensure that internal systems can authenticate requests, terminate sessions and encrypt data and systems. This is exactly what IBM Sterling Secure Proxy provides for your global enterprise.
