This is a common problem with cloud hosted SWG services that enforce access policy from outside of a customer network (e.g., external to an enterprise network), due to network address translation at the interface between the customer network and the public Internet where the cloud-hosted SWG resides. The teachings hereof address this problem. In one embodiment, a cloud hosted SWG can redirect a client to a bouncer device inside the customer network; that bouncer device can capture the actual client IP address."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device discovery for cloud-based network security gateways","description":"Among other things, this document describes systems, methods and devices for discovering and identifying client devices that attempt to access out-of-policy network services via a secure web gateway (","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11516257","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
