1. A method of transparently creating an encrypted communications channel between a client device and a target device, each device being configured to allow secure data communications between the client device and the target device over the encrypted communications channel once the encrypted communications channel is created, the method comprising:

  • (1) intercepting from the client device a request to look up an Internet Protocol (IP) address corresponding to a domain name associated with the target device;

    (2) determining whether the request to look up the IP address transmitted in step (1) corresponds to a device that accepts an encrypted channel connection with the client device; and

    (3) in response to determining, in step (2), that the request to look up the IP address in step (2) corresponds to a device that accepts an encrypted communications channel connection with the client device, providing provisioning information required to initiate the creation of the encrypted communications channel between the client device and the target device such that the encrypted communications channel supports secure data communications transmitted between the two devices, the client device being a device at which a user accesses the encrypted communications channel.
