More about the Security Headers Generator
CSP, HSTS, and X-Frame-Options each defend against a completely different kind of attack, CSP restricts which script sources a page will actually execute to blunt cross-site scripting, HSTS forces every connection over HTTPS to prevent a downgrade to plain HTTP, and X-Frame-Options stops a page from being embedded inside someone else's iframe to prevent clickjacking, three distinct defenses easy to conflate as one generic security setting. This tool generates the actual header syntax for each of these protections and more, ready to drop into a server config rather than assembled from scattered documentation. Useful for adding a Content-Security-Policy without hand-writing its directive syntax, enabling HSTS correctly on a domain that's fully moved to HTTPS, or preventing a page from being framed by an unrelated site through clickjacking.
Generate security HTTP headers including CSP, HSTS, X-Frame-Options, and more. The Security Headers Generator is one of 900+ free developer tools on Toolblip - all open to use without a signup.
