Adding a pin-coded cell phone interruptor would add some degree of addition security beyond the stock Porsche alarm.
Of course, a DIYer could install a wired ignition inhibitor with a hidden activation switch too. It's up to you whether you think the hassle or expense of one more touchscreen pin code in your life is worth it. Given the prevalence of tracking systems available these days, is theft of the vehicle more likely, or is it a smash & grab theft of items from the vehicle the more likely risk?
These days a manual transmission is the single best theft deterrent by far. Shame that Porsche couldn't offer it in every model.
