Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

1. OpenConnect can be installed via homebrew:

    brew update
   

brew install openconnect

To send a request via the sandbox, you can use pm.sendRequest.

pm.test("Status code is 200", function () {
    pm.sendRequest('https://postman-echo.com/get', function (err, res) {
        pm.expect(err).to.not.be.ok;
        pm.expect(res).to.have.property('code', 200);
        pm.expect(res).to.have.property('status', 'OK');
    });
});
