Website security hardening

Tighten the public browser boundary without playing configuration roulette.

We review the controls a visitor’s browser can observe, build a safer header baseline, stage high-risk changes such as Content Security Policy carefully, and re-test after implementation.

Baseline

Headers are small files with surprisingly large blast radiuses.

Security headers can reduce classes of browser-side risk, but a copied CSP can also break payments, analytics, maps, fonts or embedded tools. We inventory legitimate origins before enforcement.
