ParosPro Server Edition provides a multi-user web security auditing platform for companies. Paros is a valuable testing tool for your security and vulnerability testing. Paros can be used to spider/crawl your entire site, and then execute canned vulnerability scanner tests. But Paros goes beyond that, it comes with a built in utility that can proxy traffic. This Paros Proxy utility can be used to tamper or manipulate any http or https traffic on the fly. This makes some of the more interesting security types of testing. It will help you isolate potential area’s of security concern and then manual attempt to perform the type of testing you desire.
