About Contrast Security

Contrast Security sells an Application and API Security platform built to detect and stop live application-layer attacks. Contrast Security delivers real-time visibility and protection from inside running applications, using patented in-app sensors and a unified platform for Application Detection and Response and Application Security Testing. Contrast Security says that, unlike legacy tools that operate outside the application, it protects software from within.[4]

The approach rests on runtime instrumentation. Contrast instruments an application from within and observes every method, every request and every attack path as it happens. Contrast also says it reports only verified, exploitable vulnerabilities with a fix attached. The Contrast Graph links active attacks to specific lines of code in real time.[1][5]

CVE Shield deploys inside running applications without requiring code changes. CVE Shield operates within the application runtime to detect and block exploitation attempts against known vulnerabilities in third-party libraries. CVE Shield starts with Java applications on Linux-based systems. The free tier is limited to one user and up to two applications, and it provides real-time monitoring in observation mode with no automated blocking. Blocking mode is available in the Pro and Enterprise plans. Pro is a flat annual price starting at $750 a month billed annually.[1][6][7]

Contrast One is a managed Application Security service launched by Contrast Security. Contrast One is available for Application Security Testing and Application Detection and Response.[8]

Contrast Security was launched by its founder, Jeff Williams. Jeff Williams helped create OWASP in 2001. Contrast names Citizens Bank, Backbase and AARP among the companies that follow his plan. Backbase integrated Contrast Application Detection and Response to gain real-time visibility into attacks on its banking platform. Fortuneo replaced manual testing with Contrast automated, real-time protection.[4][9]

On data handling, Contrast agents minimize the data collected by reporting only confirmed vulnerabilities to the Contrast Team Server. Contrast hosts its application services and data on Amazon Web Services facilities in the United States, Europe, the UK and Japan.[1][4][5][8][9][10][11][12]
