What is HeaderKit?
HeaderKit is a focused web-header utility for teams that want to observe Content Security Policy violations before changing enforcement. It helps prepare CSP Report-Only policy packs and related review material so site owners can inspect what browsers would report while keeping the site behavior non-blocking.
HeaderKit is intentionally not a WAF, firewall, intrusion-prevention system, or general monitoring platform. It does not automatically enforce a policy, promise that a site is secure, or replace testing in each deployment environment. Review generated policy text, expected third-party resources, and browser reports before deciding what to deploy. Keep the policy under your own change control.
HeaderKit is sold for US$29 one time via Paddle. Use only authorized site information and do not submit credentials, tokens, API keys, or other secrets. The product is intended for developers and site owners who need a cautious Report-Only starting point for CSP work. Contact: idealstoronto@gmail.com. Honest scope matters: this is visibility and preparation for CSP Report-Only, not a WAF or auto-enforcing security product.
