Generate secure Nginx server blocks with TLS, HSTS, CSP, rate limiting, and access control configurations.
Nginx Security Config Generator turns deployment choices into an Nginx server-block draft combining TLS settings, HSTS and CSP response headers, request-rate controls, and address-based access rules. It prepares configuration for review; it does not prove that a host is secure. The common surprise is that these controls are not portable defaults. Certificate paths, protected locations, trusted addresses, and an effective CSP depend on the actual deployment. A restrictive CSP can block required scripts, styles, frames, fonts, or network connections even when Nginx accepts the configuration.
The result expresses each selected control using Nginx configuration syntax. TLS directives govern encrypted connections and certificate references. Response-header directives carry HSTS and CSP policies. Rate-limiting directives identify and restrict request traffic, while allow and deny rules control access by client address. These pieces must remain in configuration contexts where Nginx permits their directives.
The generated block must be reconciled with the surrounding nginx.conf. For example, a request-rate zone is defined in the http context, while its enforcement can be applied at http, server, or location level. Existing listeners, redirects, proxy settings, and header directives can also affect the final behavior. Validate the assembled configuration with nginx -t before reloading Nginx.
Usually no. First replace deployment-specific values, place directives in valid contexts, and reconcile the block with existing listeners, redirects, locations, proxies, and headers. Confirm that the selected CSP permits required resources and that access rules use the intended client address. Run nginx -t, inspect its diagnostics, and test through the same proxy path users will take before reloading.
No. It covers selected controls at the Nginx layer, but it cannot assess application authorization, injection flaws, exposed upstream services, certificate management, operating-system patching, secrets, or network policy. HSTS and CSP also require deployment-specific judgment. Treat the output as a reviewed starting point and verify the resulting headers, TLS behavior, rate limits, and access decisions.
