Acxiom client base in the United States consists primarily of companies in the financial services, insurance, information services, direct marketing, media, retail, consumer packaged goods, technology, automotive, healthcare, travel, and telecommunications industries, and the government sector.

It has been described as "one of the biggest companies you've never heard of." In addition to collecting information about people, the company helps marketers anticipate the needs of consumers, according to the documentary "The Persuaders." As the world's largest processor of consumer data, Acxiom has identified 70 types of consumers with its segmentation product PersonicX. In his 2015 book, Data and Goliath, American privacy expert Bruce Schneier wrote that Acxiom sells companies lists of consumers that include "potential inheritor," "adult with senior parent," as well as addresses of households with a "diabetic focus" or "senior needs."

Forrester Research named Acxiom one of the largest database marketing services and technology providers in the world and stated that the company “demonstrated surprising nimbleness in modernizing its offering and arguably leads the industry with its digital solutions” in their January 2011 report “The Forrester Wave™: US Database Marketing Service Providers, Q1 2011."

Acxiom is a $1.15 billion-a-year company, representing more than 12 percent of the direct-marketing-services sector’s $11 billion in estimated annual sales.

In 2003, the Electronic Privacy Information Center filed a complaint before the Federal Trade Commission against Acxiom and JetBlue Airways, alleging the companies provided consumer information to Torch Concepts, a company hired by the United States Army "to determine how information from public and private records might be analyzed to help defend military bases from attack by terrorists and other adversaries."

According to the complaint, Acxiom's activities constituted unfair and deceptive trade practices, as "Acxiom has publicly represented its belief that individuals should have notice about how information about them is used and have choices about that dissemination, and has stated that it does not permit clients to make non-public information available to individuals," yet Acxiom proceeded to sell information to Torch Concepts without obtaining consent, an ability to opt out, or furnishing notice to the affected consumers.

The FTC took no action against Acxiom, which had responded that it had followed its privacy principles and was not deceptive in its business practices. "Torch Concepts was acting under contract to the Department of Defense in their efforts to research ways to improve military base security," a company spokesman said. "Our policy clearly states that we 'provide information products which include financial information, Social Security number and other related information where permitted by law,' and that this information is 'provided to government agencies for the purposes of verifying information, employment screening and assisting law enforcement.'"

In 2003, more than 1.6 billion customer records were stolen during the transmission of information to and from Acxiom's clients; the information included names, addresses, and e-mail addresses. Prosecutors described the 2006 case against the hacker accused of stealing the data as the "largest ever invasion and theft of personal data" ever tried. The stolen data only came to light during an investigation of a separate data theft incident.

Based on their investigation, prosecutors said there was no risk of identity theft or harm to individuals based on the breaches. They also praised Acxiom for being aggressive in pursuing the hackers and cooperating with authorities. "The positive outcome of this investigation is testament to the strong partnerships we have established with our counterparts at the headquarters and field offices of various organizations, from the FBI and Department of Justice to the Internal Revenue Service and U.S. Attorneys' Office in Little Rock," said K. C. Crowley, Special Agent in Charge of Secret Service's Little Rock Field Office. "Furthermore, I commend Acxiom Corporation for their cooperation and responsible approach to the situation. Acxiom's quick response in contacting federal investigators after determining there had been a network intrusion should serve as a model for others in similar circumstances." The two primary hackers were sentenced to lengthy (8 years) prison terms.

The company is the subject of the Vienna Teng song "The Hymn of Acxiom" from her 2013 album Aims.
