Sentinel is a premium cybersecurity SaaS theme that combines the power of Next.js 16 with Keystatic CMS for a seamless content management experience. Built with the App Router and React Server Components, it delivers exceptional performance while giving content editors a visual admin interface at /keystatic to manage every aspect of the site.

Every piece of content — from site configuration and navigation to blog posts and pricing tiers — is editable through the Keystatic admin panel. Content is stored as local JSON and Markdown files, making it easy to version control with Git. For teams that need collaborative editing, Keystatic’s optional GitHub sync mode enables multiple editors to make changes that create commits directly in your repository.

The theme includes 13 fully designed pages covering everything a SaaS business needs: a conversion-focused homepage with hero section and social proof, detailed features and pricing pages, a blog with Markdown support, customer reviews, a changelog, integrations showcase, and all the standard legal pages. The design system features a dark-first cybersecurity aesthetic with a cyan and violet color palette, Space Grotesk headings, and subtle micro-interactions throughout.

Deployment is straightforward — push to Vercel and the Keystatic admin works in production alongside your statically generated pages. The serverless architecture means you get the performance benefits of static pages for your public content with the flexibility of server-rendered admin routes for content editing.
