We love finding bugs.


RIPS Technologies is a high-tech company based in Bochum, Germany, and was founded by Johannes Dahse, Martin Bednorz, and Hendrik Buchwald. We specialize in web application security and deliver automated security analysis for applications written in PHP, the most popular language on the Web. Our innovative static code analysis techniques are specifically tailored to the PHP language in order to achieve the best security analysis and performance results. Our mission is to Re-Inforce PHP Security while keeping development easy.


RIPS bases on today's most popular open-source PHP scanner that we released during the Month of PHP Security in May 2010. Due to some fundamental limitations that it has, however, we have completely redesigned it from 2013 to 2015 at the Ruhr-University Bochum. Our research was presented at the leading academic conferences, such as CCS, Usenix Security, and NDSS, and was awarded with the Internet Defense Prize by Facebook. Today, RIPS is the superior security software for PHP applications.
