Sentinel for Next.js + Contentful is a premium cybersecurity SaaS theme that combines the power of Next.js 16 with Contentful’s headless CMS. Built for security companies, SaaS startups, and technology firms, it features a striking dark-mode-first design with cyan and violet accents, gradient effects, and professional SVG mockups that make your product look enterprise-ready from day one.

The Contentful integration replaces all static data sources — features, pricing, testimonials, blog posts, team members, and more — with live CMS queries. Blog posts support Contentful Rich Text with full formatting, while maintaining backward compatibility with local Markdown files. When CMS credentials aren’t configured, the theme falls back seamlessly to local JSON data files, so buyers can start customizing immediately without setting up a Contentful space.

Every page is a React Server Component that fetches data at build time for optimal performance. The static export deploys to any hosting provider — Vercel, Netlify, GitHub Pages, or any CDN. With 26 reusable components, 14 fully-designed pages, self-hosted fonts, and a comprehensive design system, Sentinel delivers a complete product that scores 90+ across all Lighthouse categories.
