ESCRYPT CycurFUZZ sets new standards in terms of speed and error detection: thanks to the dynamic timing feature and automatic handling of test exceptions, it processes tests 8.5 times faster than other tools. Several ECUs can be fuzzed at the same time using one communication bus while taking customer-specific demands into account (e.g. ARXML files), saving you considerable time.

66 to 600 percent

ESCRYPT CycurFUZZ uncovers between 66 and 600 percent more safety-related vulnerabilities and undetected software defects than other tools.

Efficient testing for software-defined vehicles

ETAS is currently developing an open-source-based test automation framework for automotive systems together with renowned partners such as VW/CARIAD, Mercedes Benz Tech Innovation, and AVL. The project is being realized under the name “Eclipse openDuT” (Device under Test) and under the umbrella of the Eclipse Software-defined Vehicle Working Group. The aim is to create a solution that enables automated, flexible automotive testing without great expenditure of time and money.
