Choosing a static analysis tool
Choosing a static analysis tool is a difficult task since there are a lot of choices. The comparison charts below should help you decide which tool is right for you. This list is not exhaustive. The first thing to do is to look to for a tool that supports the programming language of your choice. You also have to decide whether you want a commercial tool or a free one. Usually the commercial tools have more features and are more reliable than the free ones. The major commercial tools are equally effective but their usability might differ. Next, there is the type of analysis you are looking for: Security or Quality, Static or Dynamic analysis. You should also check the compatibility of the tool with your programming environment. This was the easy part to narrow the choice down to a few tools. The next step requires you to do some work since it is quite subjective. The best thing to do is to test a few tools to see if you are satisfied with different aspects such as the user experience, the reporting of vulnerabilities, the level of false positives, the customization, the customer support… The choice should not be based on the number of features, but on the features that you need and how they could be integrated in your SDLC. Also, before choosing the tool, the security expertise of the targeted users should be clearly evaluated in order to choose an appropriate tool.
