Abstract: Techniques are described herein that are capable of using entity name mapping for routing network traffic having encrypted SNI headers. A name resolution request that specifies an entity name is intercepted. Translation of the entity name to a representation of an IP address associated with the entity name is caused. A mapping that cross-references the representation of the IP address to the entity name is stored. A data transfer request that requests establishment of a connection to a destination corresponding to the representation of the IP address is intercepted. The data transfer request includes an encrypted SNI header and a payload. Establishment of the connection to the destination is initiated by providing the encrypted SNI header, the payload, and metadata toward the destination. The metadata includes the entity name based on the mapping.
