IBM Corp. will stop selling the BlackIce PC Protection security suite, a product that came under its wing after buying Internet Security Systems (ISS) a year ago for US$1.3 billion.

The company will stop selling BlackIce on Sept. 19, and end technical support for the product, which is just for PCs running Windows, on Sept. 29, 2008, according to ISS.

IBM said its ISS division would no longer offer desktop or server protection software for the consumer market, but also noted that the company still has security software suitable for small businesses.

After the ISS acquisition users expressed concern about how IBM would continue to sell the company's stand-alone products. ISS focuses on network security products and managed security services, selling intrusion prevention and detection systems and security appliances.
