- Worth noticing
- Tool entries distinguish local-only processing from tools that reach other systems or could cause harm.
Field notes
The sample entries pair practical metadata—such as license, difficulty, deployment format, and update date—with an impact-scope label. The page describes CyberChef as processing data in the browser, while AdGuard Home is presented as a DNS server for a home or small-workplace network; the site also states that tools should be used only on owned or authorized systems.
