methodology
How this list was made
How entries are chosen. Every entry is a tool with a published profile in the catalog, in Infrastructure as Code Security. Each note above says why it made this list, for the job in the title, separately from the tool's full profile.
Ranking is editorial. The order is a judgement by the editors about fit for this use case, not a score, a benchmark or a popularity count. A different job can produce a different order.
Advertising has no influence. Slots marked Sponsored are sold separately from the editorial. No vendor can pay to be included, to move up, or to be removed.
