PII (Personally Identifiable Information) Anonymization

Personally Identifiable Information (PII) is information that can be used on its own or with other information to identify a single person, or to identify an individual in context.

It is important for us to keep personal private information out of our servers. Therefore, by default, we do not send the request body and cookies to PerimeterX backend servers, the entire communication is based on headers data.

PII is not a recommended setting. If PII is essential for your organization, contact PerimeterX Support.

When PII is enabled, PerimeterX does not store a client’s full IP information (Client IP, HTTP Headers). In IPv4 this is done by zeroing 4th IP octet (for example, the IP 1.2.3.4 will be stored as 1.2.3.0). In IPv6 this is done by zeroing the last four (4) octets (for example, the IP 1:2:3:4:1:2:3:4 will be stored as 1:2:3:4:1:2:3:0).
Removing the IP's last octet can result small reduction of detection capability, usually for the models and signatures that are based on IPs.

Test Block Flow on Monitoring Mode

Allows you to test an enforcer’s blocking flow while you are still in Monitor Mode.

When the header name is set (eg. x-px-block) and the value is set to 1, when there is a block response (for example from using a User-Agent header with the value of PhantomJS/1.0) the Monitor Mode is bypassed and full block mode is applied. If one of the conditions is missing you will stay in Monitor Mode. This is done per request.
To stay in Monitor Mode, set the header value to 0.

Default: Empty

      http_filters:
      ...
      - name: perimeterx
        typed_config:
          "@type": type.googleapis.com/udpa.type.v1.TypedStruct
          type_url: type.googleapis.com/envoy.extensions.filters.http.perimeterx
          value:
            px_bypass_monitor_header: "x-px-block"
    ...

Active Header Name

Allows you to pass a specific header (e.g. x-px-active) when px_enabled is off. When the header has a value of 1, the module is enabled for the specific request. When the header has a value of 0, the module is not enabled.

This feature can be used for a/b testing.

Default: Empty

      http_filters:
      ...
      - name: perimeterx
        typed_config:
          "@type": type.googleapis.com/udpa.type.v1.TypedStruct
          type_url: type.googleapis.com/envoy.extensions.filters.http.perimeterx
          value:
            px_active_header_name: "x-px-active"
    ...
