# Introduction and core concepts

This section is the orientation layer. Read it once and the rest of the documentation makes more sense; skip it and you'll keep bumping into terms whose definitions live here.

## What's in this section

* [What is Seal Security](/introduction/what-is-seal.md): the one-page summary of what Seal does, what it covers, and how it works alongside your existing tools.
* [What you will find in these docs](/introduction/navigating-the-docs.md): the section map and role-based starting points.
* [The remediation problem](/introduction/remediation-problem.md): why patching open-source vulnerabilities is harder than it looks.
* [The Seal approach](/introduction/seal-approach.md): how sealed packages work as drop-in replacements rather than upgrades.
* [The Seal product family](/introduction/product-family.md): one page per product across the five.
* [Architecture overview](/introduction/architecture.md): the named components, how they connect, and where your data lives.
* [Your first hour with Seal, by role](/introduction/audience-guides.md): role-based entry points (security leader, DevOps engineer, developer, security analyst).
* [Glossary](/introduction/glossary.md): the full vocabulary used across the docs.
