About Website Intelligence
What this checks
Website Intelligence looks at how safely your site is served: whether it forces HTTPS, which security response headers it sends (HSTS, Content-Security-Policy, X-Content-Type-Options and friends), and whether the platform behind it - WordPress, for instance - exposes anything it should not. These are the headers a browser reads to decide how much to trust your pages and how hard to defend the visitor.
How to read the result
HTTPS with HSTS is the baseline; missing it is the most serious finding here. The other headers are defence in depth - each one closes off a class of attack, and it is normal for a site to be missing a few. The grade weighs the important ones more heavily, so a B with two minor gaps is very different from a D that is missing HTTPS enforcement.
What to do next
Add the missing headers at your web server, CDN, or framework - most are one line of configuration. Start with HTTPS enforcement and HSTS, then work down the list. Header configuration drifts as sites are re-platformed, so re-run this after any infrastructure change, or let Nexa Monitor watch it for you.
