Guard in Chrome

Scan any page for cookie, header, mixed-content, SEO and WCAG accessibility issues, right from your own browser tab.

Guard in Chrome checks the page you're actually looking at, not a robot's snapshot of it. Most website scanners crawl your site from a server, logged out, with no cookies and no personalization. Guard runs from inside your own Chrome tab, so it sees exactly what your browser sees: HttpOnly cookies document.cookie can never read, the security headers this specific response sent, and the live DOM behind your login on the page you're checking. One click checks: • Cookies: Secure, HttpOnly and SameSite flags, read the way the browser actually enforces them • Security headers: CSP, HSTS, X-Content-Type-Options, Referrer-Policy, clickjacking protection • Mixed content: leftover http:// resources on an https:// page • Accessibility (WCAG): powered by axe-core, run against the real rendered page, not a static fetch • SEO: title/meta-description length, missing canonical or Open Graph tags, heading structure, images without alt text • Tech stack: what's actually running on the page you're on • Performance and mobile responsiveness basics No account needed to run a check. Sign in with a free Infaris account and every result is saved to your Guard dashboard, so a page you check here shows up next to your other Website Analyzer scans, and you can turn any checked site into an ongoing monitor in one click. Guard reads only the active tab, only when you click "Check this page": no background scanning, no data collected about sites you don't explicitly check. Guard by Infaris is part of the Infaris platform (infaris.com): uptime monitoring, incident management and website health, built for teams that actually get paged when something breaks.
