Matching the country code

Note

GeoIP blocking via fingerprinting is still possible, but is no longer recommended. Instead, select Country or Continent directly ias condition to block specific countries or continents.

Note

The country code comes from a GeoIP database and is not always 100% accurate.

A WAF rule with the Fingerprint condition allows you to match requests based on the country of origin (GeoIP blocking). The country code is evaluated via the iso: prefix. This allows you to specifically block or allow traffic from specific countries.

example_match'_country_1_EN

Condition for a single country code

For example, proceed as follows to match a single country:

  • ► Select Request as the request method.
  • ► Add the Fingerprint condition.
  • ► Select the EXACT operator from the drop-down list.
  • ► Enter iso:DE as the value.

example_match_country_2_EN

Condition for multiple country codes via REGEX

For example, proceed as follows to match multiple countries:

  • ► Select Request as the request method.
  • ► Add the Fingerprint condition.
  • ► Select the REGEX operator from the drop-down list.
  • ► Enter iso:(DE|AT) as the value.
