The front area of the cockpit is protected by a robust steel element integrated invisibly into the windscreen frame. The rear roll-over bars are made from high-strength steel and are located behind the seats. Their flattened form ensures high safety, and harmoniously follows the lines of the seat backrests. The upper seat-belt anchorage points are attached to the bars for greater accessibility and comfort.

Both Boxster models are equipped with Porsche Side Impact Protection (POSIP) as standard. This consists of two airbags on each side. The outer bolsters of the seats contain a thorax airbag and each door contains a head airbag. Each has a volume of around 8 litres, ensuring high protection in the event of a side impact, even when the hood is open. The passenger cell is also shielded by side impact protection beams in the doors.
