The invention relates to a woven wire netting (10), for use preferably as protection against rock fall or to secure a top layer of soil, which is woven out of corrosion resistant wires (11, 12, 13, 14) and either spread across the ground or fastened in a substantially vertical position to a slope or such like. The wires (11, 12, 13, 14) of the woven wire netting (10) are made of high- strength steel. Said high-strength steel wire has a nominal strength of between 1,000 and 2,200 N/mm2 and can be made of steel wire suitable for wire ropes or steel spring wire. The woven wire netting is made from a rectangular diamond netting and has a three-dimensional mattress-like structure.
