We are pleased to announce that the Bot Management product now includes support for JA4 fingerprinting. This enhancement expands our existing fingerprinting capabilities to provide more detailed client identification during TLS-encrypted communications.

JA4 fingerprinting is available for Edge deployments running version 2.10.0 or later. To enable this feature, ensure your Edge deployment is updated to a supported version. If your deployment is running an earlier version, you will need to update by re-mapping your Fastly VCL service. For instructions, see [Re-mapping a Fastly VCL service](https://www.fastly.com/documentation/guides/next-gen-waf/setup-and-configuration/edge-deployment/ngwaf-control-panel/maintaining-edge-waf-deployments-using-the-next-gen-waf-control-panel#updating-the-edgemodule-version).

If you have any questions or need assistance, contact your Fastly account team or reach out to our [support team](https://support.fastly.com).
