What Really Happened has an interesting round up about the Bush family's control of security at both the World Trade Center and Dulles airport on 9/11:

"Marvin P. Bush, the president’s younger brother, was a principal in a company called Securacom that provided security for the World Trade Center, United Airlines, and Dulles International Airport. The company, Burns noted, was backed by KuwAm, a Kuwaiti-American investment firm on whose board Marvin Burns also served. [Utne]

According to its present CEO, Barry McDaniel, the company had an ongoing contract to handle security at the World Trade Center "up to the day the buildings fell down."

The company lists as government clients "the U.S. Army, U.S. Navy, U.S Air force, and the Department of Justice," in projects that "often require state-of-the-art security solutions for classified or high-risk government sites."

Stratesec (Securacom) differs from other security companies which separate the function of consultant from that of service provider. The company defines itself as a "single-source" provider of "end-to-end" security services, including everything from diagnosis of existing systems to hiring subcontractors to installing video and electronic equipment. It also provides armored vehicles and security guards.

The Dulles Internation contract is another matter. Dulles is regarded as "absolutely a sensitive airport," according to security consultant Wayne Black, head of a Florida-based security firm, due to its location, size, and the number of international carriers it serves.

Black has not heard of Stratesec, but responds that for one company to handle security for both airports and airlines is somewhat unusual. It is also delicate for a security firm serving international facilities to be so interlinked with a foreign-owned company: "Somebody knew somebody," he suggested, or the contract would have been more closely scrutinized.

As Black points out, "when you [a company] have a security contract, you know the inner workings of everything." And if another company is linked with the security company, then "What's on your computer is on their computer." [American Reporter]
