Security tools are a mess. Dozens of acronyms, overlapping features, and plenty of buzzwords pretending to be categories. This chapter clears the fog and gives you a no-bullshit framework to understand how software security tools actually work—and how to group them in a way that makes sense to devs, not marketers. 

If you’re just getting started, this is where to start. No fluff. Just clarity.

Feel free to skip irrelevant sections, this is not a boring whitepaper.
