Sentinel Next.js + Sanity is a premium cybersecurity SaaS website theme that combines the power of Next.js 16 App Router with Sanity headless CMS. Built with a dark-first design aesthetic using Tailwind CSS v4, it delivers a polished, professional look that’s perfect for security companies, SaaS startups, and technology firms.

The theme features complete Sanity CMS integration with GROQ queries for all content types — blog posts, features, pricing plans, testimonials, team members, FAQ, changelog, and more. When Sanity credentials are not configured, it falls back to local JSON data files, so the theme works out of the box with zero setup. Blog posts support both Portable Text (from Sanity) and Markdown (local files) with automatic detection.

With 13 fully designed pages including a feature-rich homepage, blog with table of contents, pricing with monthly/yearly toggle, customer reviews, integrations showcase, and changelog — Sentinel provides everything you need to launch a professional cybersecurity or SaaS website. All pages are fully responsive, SEO optimized, and statically exported for fast performance on any hosting platform.
