HUMAN Fastly Enforcer is a Varnish Configuration Language (VCL) based module that runs on Fastly's edge, detects and blocks unwanted traffic from reaching the origin. When the HUMAN Enforcer determines that a request is coming from a non-human source, the request is handled according to the configurations. Protecting your website with HUMAN's Fastly VCL integration supports both regular service and service using shielding.
