Updated from 4:38 p.m. EDTInternet Security Systems ( ISSX) posted second-quarter earnings in line with the Street but missed on the top line. For its second quarter, the security software and appliance company earned $6.2 million, or 14 cents a share, falling from $8.3 million, or 18 cents a share in the same period last year. Excluding certain items, ISS earned $9.7 million, or 22 cents a share, compared with $9.7 million, or 21 cents a share in the year-ago quarter. On that basis, ISS hit analysts' projections on target. ISS reported revenue $82.7 million, while analysts had anticipated $85.3 million. A year ago, ISS recorded $79.1 million in sales. "I am very pleased with the strong demand patterns for our new Proventia solutions, which delivered solid growth this quarter. Additionally, I am proud to note that our Proventia Intrusion Prevention solutions grew 23% annually, while our Proventia Unified Threat Management solutions revenue grew 55% annually," Tom Noonan, president and CEO, of ISS said in a statement. In a call with financial analysts after the bell, Noonan said that revenue fell short of expectations because of a transition to a new logistics system. The company was unable to fulfill about $2 million of committed orders in full because of the hiccups. In order to address the problems, the company said its contract manufacturer will expand its shipping lanes and ISS will open a new West Coast shipping location. Despite the botched orders, demand was considerably stronger than the sales figures suggest, Noonan said. Intrusion prevention is a proven technology and has gained mainstream acceptance, Noonan said. "As the market-share leader, I think that puts us in a very good position to continue to grow rates faster than the market," he said.
