External services
This plugin optionally connects to the following third-party / external services. Each service is only contacted when its corresponding module is enabled and the described conditions are met.
Google reCAPTCHA (Google LLC)
What it is and what it is used for: Google reCAPTCHA is a bot-detection service. CoxWall uses it to protect the WordPress login, registration, lost-password, comment, and WooCommerce My Account forms from automated attacks.
What data is sent and when: When the CAPTCHA module is enabled, two types of requests are made to Google:
01Front-end (page load) – the visitor’s browser loads the reCAPTCHA JavaScript library directly from Google’s CDN ( www.google.com ). Google receives the visitor’s IP address, browser and device information, and the site’s public reCAPTCHA site key.
02Back-end (form submission) – when a visitor submits a protected form, the plugin sends the reCAPTCHA response token, the site’s secret key, and the visitor’s IP address to Google’s verification endpoint ( www.google.com/recaptcha/api/siteverify ) to confirm the response is valid.
No data is sent if the CAPTCHA module is disabled or if no reCAPTCHA site/secret key has been configured.

WordPress.org Core Checksums API (WordPress.org)
What it is and what it is used for: The WordPress.org Checksums API provides official MD5 hashes for every file in each WordPress core release. CoxWall’s File Integrity module uses these hashes to detect unauthorized modifications to core files.
What data is sent and when: When a file integrity scan runs (manually triggered or on schedule), the plugin sends a GET request to https://api.wordpress.org/core/checksums/1.0/ containing:
The installed WordPress version number.
The site’s configured locale/language.
No personal data, user data, or site content is transmitted. The request retrieves a publicly available checksum list.

Appsero SDK does not gather any data by default. The SDK only starts gathering basic telemetry data when a user allows it via the admin notice . We collect the data to ensure a great user experience for all our users.
Integrating Appsero SDK DOES NOT IMMEDIATELY start gathering data, without confirmation from users in any case.

Frequently asked questions.
Does CoxWall block attacks before WordPress or PHP runs?
No. CoxWall is a WordPress plugin, so it runs inside WordPress: every request it blocks has already reached your server and started PHP. It stops the attack, but the server still does some work for each request.
To refuse abusive traffic earlier, go to CoxWall → Early Blocking . It generates rules for this site’s login and XML-RPC addresses that you (or your host) add to Cloudflare, Nginx, or Apache. Those rules act before PHP starts. CoxWall does not edit server configuration files or your Cloudflare account; you apply the rules yourself. Keep CoxWall enabled as a second layer behind them.
My site is behind Cloudflare or a load balancer. What do I need to set?
Go to CoxWall → Early Blocking → Cloudflare → Visitor IP Detection and turn on Behind Cloudflare , or list your load balancer’s IPs under Trusted Proxies . Otherwise every visitor appears to come from the proxy’s IP, and login lockouts or IP blocks would affect everyone.
