  • Patent number: 11811773
    Abstract: A technique provides access to content within a computing environment. The technique involves identifying a network address to a resource which is currently blocked from being accessed via the network address due to operation of a content filter. The technique further involves, based on previously accessed content, modifying the operation of the content filter to unblock access to the resource via the network address. The technique further involves, after the operation of the content filter is modified to unblock access to the resource via the network address, permitting access to the resource via the network address.

  • Patent number: 11722465
    Abstract: Methods, systems, computer-readable media, and apparatuses may provide password encryption for hybrid cloud services. A workspace cloud connector internally residing with an entity may intercept user credentials associated with an internal application being transmitted to an external cloud service. The workspace cloud connector may generate an encryption key and encrypt the user credentials via a reversible encryption methodology. The workspace cloud connector may encrypt the encryption key using an irreversible encryption methodology (e.g., use a hashing function to produce a first hash). The workspace cloud connector may transmit the encrypted user credentials and the first hash to a virtual delivery agent via a first path (e.g., via the external cloud service). In response, the workspace cloud connector may receive an address of the virtual delivery agent and, using the address, may send the encryption key to the virtual delivery agent via a second path different from the first path.

  • Patent number: 11637912
    Abstract: Methods, systems, computer-readable media, and apparatuses may provide for the intermediated retrieval of applications on a network. A computing device may be configured to receive an application from an application server on a network. Based on, for example, the network conditions between the computing device and the application server, the computing device may query a plurality of intermediary servers. Based on a decision that, for example, the network conditions between the computing device, application server, and a selected intermediary server are better than the network conditions between the computing device and the application server, the computing device may cause the application to be retrieved by a host application of the selected intermediary server. The host application may process and transmit the application to the computing device.

  • Patent number: 11522847
    Abstract: Aspects described herein relate to methods, devices and systems that allow for a client device, as part of a remote access or cloud-based network environment, to map external user identities to desktops and applications. Local user accounts can be dynamically generated on a virtual delivery agent. A mapping of the local user account to an external identity can be secured using signed tokens and maintained by a broker machine that allocates resources for the deployment of particular applications to the client device from the virtual delivery agent. This allows for the removal of any dependency on an Active Directory for maintaining user identities or federated sign-on services, greatly simplifying the management of user identities within the system and allowing for greater compatibility across client devices.

  • Patent number: 11463529
    Abstract: A virtual delivery appliance may include a memory and a processor configured to cooperate with the memory to connect client computing devices with virtual computing sessions provided by a host computing device(s) based upon respective connection leases each including an ordered list of virtual delivery appliances, with at least some of the client computing devices having different ordered lists of virtual delivery appliances. Each client computing device may be configured to request a new session from the virtual delivery appliances in the ordered list in descending order until receiving a connection with a new virtual computing session. The processor may be further configured to re-direct new session requests received from the client computing devices to lower virtual delivery appliances in the ordered list when existing virtual computing sessions for the client computing devices are already active with the host computing device(s) associated with the lower virtual delivery appliances.
