Microsoft Proxy Server Log Analyzer

Can you recommend a product that will report on both Web Proxy as well as Winsock Proxy Logs – WSxxxxxx.log and Wxxxxxxxx.log?
I have looked at a few with WebTrends being the most promising one. Although WebTrends will reports on Winsock Proxy logs, they are not fully supporting it. All the other ones I have looked at only support Web Proxy.
Many Thanks in advance.
