In reply to Richard.

Luckily I have not been forced to use surveillance tech for a while. I once had a client ship me a laptop to access their systems. It took 20 minutes to boot up and had keystroke logging and many other tracking devices installed. I would send myself emails to my client account and then copy & paste, to avoid this crappy system. I once saw a senior executive's laptop shut down to install an update while he was giving a presentation. He had no control over his machine. It was insane.
