Hey Gilligan, will you hold this lightning rod for me..?
check the net under fire extinguishers.
lightning will damage equipment no matter how well grounded.( Don't let the insurance company get by with that excuse.)
If you bypass your work network security they will know it and terminate you! They have it blocked for a reason, it violates their electronic communication policy! If you violate this policy it's grounds for termination so don't do it, unless you want a new job.
