raw data, leading to accusations that their conclusions are overly sunny. One NMCI director, Rear Admiral James B. Godwin III, said releasing the results would challenge the "integrity of our data." The Department of the Navy has shown no desire to scale back or cancel the program. On 24 March 2006 the Navy exercised its three-year, $3 billion option to extend the contract through September 2010. In April 2006, users began to log on with Common Access Cards (CACs), a smartcard-based logon system called the Cryptographic Log On (CLO). In October 2008, NMCI's prime contractor HP posted a set of procedures so Apple Mac users can access NMCI's public-facing Web services, such as the e-mail and calendar functions, using their CAC readers with their Macs. The workaround also works with other Defense Department CAC-enabled networks. Alternatively, NMCI and all other CAC-authenticated DoD websites may be accessed using LPS-Public. After early challenges, the Navy is pleased with the performance and security of the NMCI network. According to Captain Tim Holland, program manager for the Navy's Next Generation Enterprise Network (NGEN), "NMCI is very robust today—we have good security with it, very good performance." In an interview the DoN CIO Robert J. Carey stated, "The plan is that NGEN <Next Generation Enterprise Network > will be in place before the NMCI contract expires because it is not a renewable contract. According to the Navy, NMCI will serve as the baseline from which it will transition to NGEN. The Navy's confidence in NMCI today marks a significant turnaround from the challenges cited in the GAO’s report of December 2006. The report states that " NMCI has not met its two strategic goals—to provide information superiority and to foster innovation via interoperability and shared services." The document also goes on to evaluate HP's performance, "GAO's analysis of available performance data, however, showed that the Navy had met only 3 of 20 performance targets (15 percent) associated with the program's goals and nine related performance categories." In contrast are the more recent comments from Vice Admiral Harry B. Harris Jr., deputy chief of naval operations for communication networks (OPNAV N-6) and deputy chief information officer, Department of the Navy. "I believe that NMCI in 2008 is achieving much of what we had hoped NMCI would achieve. It's leveled the playing field for security. It's allowed us to do things like push security patches that go
