About this product

Security headers are easy to set and easy to get subtly wrong. This pack contains 150 tested configurations: Content-Security-Policy for common front-end stacks and third-party services, HSTS rollouts, permissions policies, cross-origin isolation, and cookie hardening for popular frameworks.

Configurations are provided for Nginx, Apache, Caddy, Cloudflare and framework middleware, each with a report-only variant for safe rollout. Your fare unlocks groups in the listed order.

You choose the fare: anything from €1 to €100, in whole euros. At €100 you get every part, plus all future additions to it.

Frequently asked questions

Still unsure about something? Write to our contact page and a human answers, usually the same working day.

Pick any whole-euro fare from €1 to €100. Each euro unlocks 1.5 policies, and parts unlock in the order listed on this page, so you see exactly what your fare includes before you pay.

No. New policies added to the parts you have unlocked appear behind the same download link at no extra cost.

Checkout is handled on our provider's secure payment page. The moment your payment clears we email your personal access link and access code to the address you used at checkout, and the same link appears in your account library. There is nothing to install and nothing to wait for.
