Flex Website Security is a lightweight hardening toolkit — not a full WAF or malware scanner. It reduces common attack surfaces: brute-force logins, XML-RPC abuse, user enumeration, and loose admin defaults.

Limit failed login attempts, with a lockout list you can unblock immediately
Permanently block or unblock IPs
Restrict by country: Allow from or Restrict from, on the whole site or admin only
Custom login URL and hide wp-admin for guests
Optional Cloudflare Turnstile or Google reCAPTCHA on login forms
Login honeypot and generic login errors
Disable XML-RPC and the theme/plugin file editor
Hide WordPress version
Block user enumeration
Basic security headers (HSTS is left to Flex SSL)

Admin CSS and JavaScript ship with the plugin. Remote scripts and API calls run only when you enable captcha or the optional country lookup.

Privacy

IP lockouts and permanent blocks are stored in your WordPress database. Only administrators can view or change them on Flex Website Security Access.

Captcha (off by default): if you choose Cloudflare Turnstile or Google reCAPTCHA and save both keys, the login form loads that provider’s script and sends the visitor IP plus the captcha token to the provider for verification.

Country lookup (off by default): country rules first use CDN headers (Cloudflare, CloudFront, and similar). If you enable the optional geojs.io lookup, public visitor IPs without a header are sent to geojs.io and cached for 7 days.

See Third-party services below for URLs, terms, and privacy policies.

Third-party services

These services are optional and off by default. No third-party script is loaded unless you choose a captcha provider and save both keys, or you enable the geojs.io lookup.

Cloudflare Turnstile

When enabled, the login form loads https://challenges.cloudflare.com/turnstile/v0/api.js and verifies tokens at https://challenges.cloudflare.com/turnstile/v0/siteverify. Cloudflare receives the visitor IP and token.

Service: https://www.cloudflare.com/application-services/products/turnstile/

Privacy: https://www.cloudflare.com/privacypolicy/

Google reCAPTCHA

When enabled, the login form loads https://www.google.com/recaptcha/api.js and verifies tokens at https://www.google.com/recaptcha/api/siteverify. Google receives the visitor IP and token.

Service: https://www.google.com/recaptcha/about/
Terms: https://policies.google.com/terms

geojs.io

When enabled on Access, visitor IPs without a CDN country header are looked up at https://get.geojs.io/v1/ip/country/{ip} and cached for 7 days.

Service: https://www.geojs.io/
Terms / privacy: https://www.geojs.io/
