The Contrast Java agent analyzes the behavior of Java applications running on J2EE containers; newer frameworks like Netty, Play or Vert.X; FatJar/microservice applications like SpringBoot; or even regular desktop Java applications. If there's a JVM, the Java agent can get security insights.

How It Works

To start analyzing an application, install the Java agent by adding it as -javaagent JVM parameter. After installation, continue to use the application as you normally would. (If it's a web application, just click on links, submit forms using normal data, and so forth.) The Java agent's sensors gather information about the application's security, architecture and libraries. You can see the results of the agent's analysis in the Contrast UI.

Note for Proguard Users

Proguard includes Java bytecode optimization features which break basic assumptions that runtime agents like Contrast rely on. Proguard users that want to protect their applications with Contrast need to avoid these optimizations by using Proguard's -dontoptimize configuration option.
