Build precise policies
Block or allow countries, add trusted IP and ASN exceptions, target hostnames and paths, and schedule changes in advance.
Policy-driven protection for every request
Control where your website traffic comes from.
Block countries, networks, and unwanted traffic with policies you can explain. Preview the impact, publish safely, and keep a complete history—without turning access control into a maintenance project.

Control without guesswork
A safer workflow for geographic access control.
From the first policy draft to a verified deployment, every step is visible, reviewable, and reversible.
Preview before publishing
See affected countries, required datasets, validation problems, and possible lockouts before a rule reaches production.
Generate with confidence
Produce deterministic Cloudflare, Nginx, Apache, or CIDR artifacts tied to an immutable policy and dataset version.
Verify and roll back
Confirm Cloudflare state after deployment, preserve the previous version, and return to a known-good configuration when needed.
Understand blocked traffic
Measure blocked requests, countries, reasons, trends, and estimated visitors with privacy-preserving telemetry.
Give visitors a clear answer
Choose a local 403 or a branded hosted block page with a safe reference ID for faster support.
From policy to protection
Go live in three deliberate steps.
BlockACountry keeps the hard parts—datasets, policy evaluation, configuration syntax, and deployment history—in one dependable workflow.
- 01
Connect your website
Add a domain and verify ownership. Connect Cloudflare with OAuth, or choose a generated server configuration.
- 02
Define and review
Choose countries and exceptions, select enforcement, then use impact preview and lockout analysis before publishing.
- 03
Deploy and observe
Generate or deploy the immutable revision, verify its state, and follow protection health and privacy-conscious analytics.

Secure by design
Protection remains the priority—even when telemetry is unavailable.
Policies continue to block locally or at the edge. Hosted pages and analytics add explainability, but they never become a dependency for enforcement.
- Cloudflare connects through OAuth—no long-lived API keys in the dashboard.
- Every configuration is tied to a specific policy revision and dataset snapshot.
- Telemetry uses rotating keyed fingerprints instead of retaining raw IP addresses indefinitely.
- Unsafe request bodies and sensitive query strings are never forwarded to hosted block pages.
