IBM Security AppScan previously known as IBM Rational AppScan is a family of web security testing and monitoring tools from the Rational Software division of IBM. AppScan is intended to test Web applications for security vulnerabilities during the development process, when it is least expensive to fix such problems. The product learns the behavior of each application, whether an off-the-shelf application or internally developed, and develops a program intended to test all of its functions for both common and application-specific vulnerabilities.
IBM Security AppScan enhances web application security and mobile application security, improves application security program management and strengthens regulatory compliance. By scanning your web and mobile applications prior to deployment, AppScan enables you to identify security vulnerabilities and generate reports and fix recommendations.
