# Introduction and core concepts

What Seal is, the remediation problem it solves, and the vocabulary you'll see across these docs.

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.
