Sentinel for Bootstrap is a premium cybersecurity SaaS theme that combines Bootstrap 5.3’s proven component library with a custom dark-first design system. Built for security companies, SaaS platforms, and tech startups, it delivers 19 fully designed pages covering everything from a feature-rich homepage to blog posts, pricing tables, and legal templates — all output as pure HTML, CSS, and JavaScript with zero framework dependencies in production.

The theme uses Bootstrap’s native components — accordion, offcanvas navigation, cards, modals — enhanced with custom Sass theming that maps the Sentinel design system onto Bootstrap variables. Glassmorphism card effects, gradient text accents, mesh gradient backgrounds, and smooth micro-interactions give it the premium feel of a custom-built SaaS marketing site, while the underlying Bootstrap foundation means it’s easy to extend and customize.

Every page is fully responsive from 320px mobile screens to 1440px+ desktops, with a dark/light theme toggle that persists in localStorage. The blog features pre-rendered Markdown content with featured images and a sticky table of contents sidebar. The pricing page includes a monthly/yearly toggle, and the integrations page offers category-based filtering. Self-hosted Inter and Space Grotesk variable fonts ensure there are no external CDN dependencies, and the entire build produces clean static files ready for any hosting provider.
