    I'm not sure I can help you on the contacting process, but question you assumptions.

    My company has made a conscious decision to leave our WiFi open to visitors, while our internal machines connect via IPSec on the open airwaves.
    A drive-by would show the open nature of our WiFi, but wouldn't immediately tell you that we've secured our business fairly well.
