PentestingChecklist preview

Comprehensive, data-driven security assessment checklists across 23 platforms web, API, mobile, cloud, Active Directory, Kubernetes, LLM, and more. Expandable hierarchy, global search, progress tracking, export.

  • Hierarchical checklist — content is organised in four levels, Platform → Category → Technology → Check, so the tool works like a real assessment framework rather than a flat list. Expand/collapse categories and technologies, with item counts on every section and one-click Expand all / Collapse all.
  • Global search — press ⌘K / Ctrl+K from any page to search across platforms, categories, technologies, checks, descriptions, tags, tools, and references. Selecting a result jumps to it, auto-expands the right sections, and highlights the item.
