Abstract: Methods, apparatus, systems and articles of manufacture to implement a virtual private network with probe for network connectivity are disclosed. An example non-transitory computer readable storage medium is disclosed comprising instructions which, when executed, cause a machine to at least, in response to a first instruction from an operating system to establish a network tunnel, transmit a probe request to a server; and in response to not receiving, from the server, a probe response to the probe request, report that the network tunnel has been established to prevent the operating system from transmitting subsequent instructions to establish the network connection until a response to a probe request is received.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform, including a processor and a memory; and executable instructions encoded in the memory to provide a client-only virtual private network (VPN) including a VPN client and a VPN server implementation on a single physical device, wherein the VPN client is configured to communicatively couple to the VPN server and to provide proxied Internet protocol (IP) communication services.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform, including a processor and a memory; and executable instructions encoded in the memory to provide a client-only virtual private network (VPN) including a VPN client and a VPN server on a single physical device, wherein the VPN client is configured to communicatively couple to the VPN server and to provide proxied Internet protocol (IP) communication services via the VPN server.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform including a processor and a memory; a user application; telemetry probes to collect telemetry about use of the user space application; a detection proxy to collect telemetry data from the telemetry probes and forward the telemetry data to a detection cloud service; and logic to receive from the detection cloud service a detection message that the user application has exhibited behavior consistent with tampering, and to take remedial action responsive to the detection message.

Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform including a processor and a memory; a closed operating system including instructions within the memory to sandbox userspace applications; and a sandboxed userspace application, including: instructions to provide a user interface and user application code; and an agentless security library within the sandboxed userspace application, the agentless security library including instructions to provide security or privacy services to the sandboxed userspace application with minimal direct interaction from the user interface and user application code.

Abstract: In an example, there is disclosed a computing apparatus, including: a hardware platform comprising a processor and a memory; software to access a network or internet resource according to a domain name; a network stack to provide network or internet access; and a virtual private network (VPN), configured to locally intercept a domain name-based access request, query a domain policy repository to determine whether the domain name should be blocked, and to query an external domain name system (DNS) server for an internet protocol (IP) address for the domain name and pass the request through the network stack if the domain name should not be blocked.
