Open source is part of almost every software capability we use today. At the very least libraries, frameworks or databases that get used in mission critical IT systems. In some cases entire systems are built on open source foundations. This report reviews some of the most commonly used open source software (OSS) projects. We compare them to each other, and to enterprise IT. Some of our findings surprised us, some were expected.

Whatever your take, it’s clearly important to know what OSS components you have, and what kinds of software flaws you may be inheriting from these components. Start by getting a general sense from our Software Intelligence Report.
