CNO Financial Group, Inc. (formerly Conseco, Inc. (from Consolidated National Security Corporation; NYSE: CNO) is a financial services holding company based in Carmel, Indiana. CNO's insurance subsidiaries provide life insurance, annuity and supplemental health insurance products to more than four million customers in the United States. These products are distributed through independent agents, career agents and direct to customers through television advertising and direct mail.

CNO ranked 608 on the Fortune 1000 with 2014 revenues of $4.1 billion. In April 2014 CNO was ranked top 50 most trusted financial institutions by Forbes.

CNO was incorporated in 1979 as Security National of Indiana Corp. by Stephen Hilbert. SNI bought Consolidated National Life Insurance Co. in 1983. It began insurance operations in 1982 and became a public company in 1985.

In 1986 Conseco acquired Lincoln Income Life Insurance Company for $29 per share or $32.3 mil. Shearson Lehman Brothers advised Lincoln Income Life Insurance. Earlier, in mid-1985, Lincoln had agreed to be acquired by I.C.H. for $31 per share in cash but the merger couldn't be consummated as the Kentucky Department of Insurance raised objections to certain expenses which Lincoln would have incurred in the merger. Lincoln also received a merger proposal from Redgate in 1985. Satisfied with its recipe for acquiring and improving insurance companies, Conseco stepped up its acquisition efforts in 1986. It purchased Bankers National Life Insurance Company for $118 million, respectively.

In 1998, Conseco purchased the former Greentree Financial, one of the largest financiers of mobile homes, in an attempt to diversify into consumer financial services. They also bought life insurance company Colonial Penn later that year, changing their name to Conseco Direct Life, though changing the name back to Colonial Penn in 2001 (known as Bankers Conseco Life Insurance Company in New York state). Conseco (though not its subsidiary insurance companies) entered Chapter 11 reorganization in 2002 and emerged nine months later in 2003. Conseco's bankruptcy was the third-largest U.S. Chapter 11 filing at the time, after the bankruptcies of WorldCom Inc. and Enron. In the process of reorganization, GreenTree was divested and thereafter Conseco solely focused on the insurance industry.

CNO's CEO, Edward Bonach, joined the company in May 2007 as CFO and later became CEO in October 2011. Bonach is also a member of CNO's Board of Directors.

CNO is the parent company of seven insurance companies, including Bankers Life and Casualty Company and Colonial Penn Life Insurance Company. They also owns 40/86 Advisors, an investment management company and Washington National Insurance Company.

On May 11, 2010, the board of directors officially approved changing the holding company's name to CNO Financial Group.

In 2015 February, CNO sold its Hyderabad-based India operations to Cognizant.
