  • Patent number: 11575714
    Abstract: This invention provides secure, policy-based separation of data and applications on computer, especially personal computers that operate in different environments, such as those including personal applications and corporate applications, so that both types of applications can run simultaneously while complying with all required policies. The invention enables employees to use their personal devices for work purposes, or work devices for personal purposes. The secure, policy-based separation is created by dividing the data processing device into two or more “domains,” each with its own policies. These policies may be configured by the device owner, an IT department, or other data or application owner.

  • Patent number: 11096054
    Abstract: The invention provides a method for managing access to a network resource on a network from a mobile device, the method including the steps of intercepting a data stream from the mobile device attempting to access the network resource, extracting information from the intercepted data stream relating to at least one of the mobile device or a user of the mobile device, accessing at least one of enterprise service based information and third party information regarding at least one of the mobile device or the user of the mobile device, determining whether the mobile device is authorized to access the network resource, preparing an access decision that specifies whether the mobile device is authorized to access the network resource, and storing the access decision in a database on the network.

  • Publication number: 20200336466
    Abstract: Systems, software, and methods are provided for providing simpler and more secure ARSs that operate to separate and isolate configuration details from connecting systems by: moving most of the connection information to the easily secured ARS; requiring endpoints to initiate outbound connections to that server instead of exposing the systems to inbound connections from the internet; consolidating policy enforcement and routing decisions from the individual endpoints to an ARS; and consolidating network packet traffic filtering and monitoring in an ARS. The present invention substantially reduces the complexity of endpoint configurations by offloading most of the connection and endpoint validation, policy enforcement, information leakage management, and routing decisions from the endpoints to an ARS.
