Sentinel for Astro + Decap CMS is a premium cybersecurity SaaS theme that combines a polished, production-ready frontend with a powerful Git-based content management system. Built on Astro 5 and Tailwind CSS v4, it delivers exceptional performance while giving content editors a visual admin panel to manage every aspect of the site.

Unlike traditional CMS integrations that require external databases, API keys, and complex setup, Sentinel + Decap CMS keeps everything in your Git repository. Blog posts, pricing tiers, team members, testimonials, FAQ entries, and site configuration are all editable through the browser-based admin UI at /admin. Changes are committed directly to your repo, giving you full version history and the ability to roll back any edit.

The theme ships with 13 pages, 20+ components, and 11 CMS-editable content collections covering blog posts, site settings, navigation, features, pricing, testimonials, team members, FAQ, changelog, integrations, and social proof. Authentication is handled through Netlify Identity (zero-config on Netlify) or GitHub OAuth for self-hosted deployments. For local development, the included decap-server proxy lets you edit content without any authentication setup.

Whether you’re building a cybersecurity product site, a SaaS landing page, or any professional business website, Sentinel + Decap CMS gives you the design quality of a premium theme with the content flexibility of a headless CMS — all without external service dependencies.
