The American retail multinational Wal-Mart has began testing the sale of computer and network security products and services. In Houston, Texas, the company has leased land next to its super-centre to security product vendor, SNP Group Inc. The new security super-store will stock security hardware, software and have professional Walmart trained security professionals offering deep discount prices. Wal-Mart is the largest retailer in the world, with 1.2 million workers. Company spokesperson, Smy Leeface, said " all employees will undergo a rigorous three day course of security training at Wal-Mart SecU, where they will be taught the difference between a router and a grinder. Graduates of Wal-Mart SecU will be able to sell a firewall while ringing up a sale for a pair of pants or a carton of Depends ". Security professionals and their certification boards have warned that the disruption caused by the arrival of Wal-Mart in the security industry and an increased focus on price competition could mean lower quality network security and services and thus a loss for customers. At the same time, many jobs would be lost, particularly in smaller security firms which could not continue to be competitive.
