How to fix server version on Shopify

Steps for Shopify

1. Shopify is a fully hosted SaaS platform — you do not have access to the underlying web server configuration files.
2. Shopify manages all server headers centrally. The `Server` header on Shopify storefronts is already genericised (it does not expose a version number); no action is needed or possible from the theme or admin.
3. If a scanner flags a version header on a Shopify store, confirm the request is hitting your Shopify domain (*.myshopify.com or your custom domain pointed to Shopify) and not a third-party app proxy or custom server you separately manage.
4. For any custom storefronts built with the Shopify Storefront API hosted on your own server, apply the server-level fix appropriate for that server (Nginx, Apache, etc.) as described in the generic steps above.

# Apache (httpd.conf or .htaccess)
ServerTokens Prod
ServerSignature Off
Header unset X-Powered-By

# Nginx (nginx.conf — inside http{} or server{} block)
server_tokens off;
# (requires headers_more module for full removal:)
more_clear_headers 'Server';
more_clear_headers 'X-Powered-By';

# PHP (php.ini)
expose_php = Off

# Next.js (next.config.js)
module.exports = { poweredByHeader: false }

What is server version?

Every time a visitor's browser (or a bot) loads a page on your store, your web server sends back a set of invisible "response headers." One of these is the `Server` header, and by default most web servers announce themselves with their exact name and version number — for example, `Server: Microsoft-IIS/10.0` or `Server: Apache/2.4.51`. A related header, `X-Powered-By`, can also reveal the scripting language or framework version (e.g., `X-Powered-By: PHP/8.1.2`). Together these are called "server version disclosure" or "banner grabbing." Neither header has any meaningful purpose for shoppers — they exist purely as leftover defaults.

Advertising your exact server software and version is like posting a sign on your shop door listing every lock brand and model you use. Automated attack tools (bots) continuously scan the internet for sites running specific software versions with known vulnerabilities. When your version is visible, your store becomes an easy target: attackers can instantly match your version against published vulnerability databases (CVE lists) and launch targeted exploits — without any guesswork. Suppressing these headers does not make your server invulnerable, but it removes you from the easiest tier of automated attack campaigns. It also demonstrates security hygiene to enterprise buyers and payment-card auditors (PCI DSS Requirement 2.2.7 addresses unnecessary information disclosure), reducing compliance friction.
