SecureWorks Inc. is a United States-based subsidiary that provides information security services, protecting its customers' computers, networks and information assets from malicious activity such as cybercrime. The company has approximately 4,400 customers across 61 countries, ranging from Fortune 100 companies to mid-sized businesses in a variety of industries. It became part of Dell in February 2011 and branched off to become a public organization in April 2016. It is still majority-owned by Dell.

SecureWorks was founded as a privately held company in 1998 by Michael Pearson and Joan Wilbanks. In 2002 Michael R. Cote became President and CEO. In 2005, and again in 2006, the company was named to the Inc. 500 and Inc. 5000 lists (2005, 2006) and Deloitte’s Fast 500.

In 2006, SecureWorks merged with LURHQ Corporation and the new entity continued under the SecureWorks corporate name. LURHQ, which was founded in 1996 in Myrtle Beach, SC and provided managed security services to large enterprises, had similar company cultures and leadership to SecureWorks. According to Gartner, the merger created a stronger company. With the merger, SecureWorks was able to leverage Sherlock, LURHQ's portal, to unify its combined customer base onto a single integrated security management platform.

In 2009, SecureWorks acquired the Managed Security Services (MSS) business from VeriSign, Inc., a provider of Internet infrastructure services for the networked world, and grew to more than 500 employees worldwide. The acquisition expanded its clients to approximately 2,600 in more than 50 countries, including the United Kingdom, Saudi Arabia, Taiwan, Finland, Spain, Brazil and Mexico. This includes four of the Fortune 10. Also in 2009, SecureWorks acquired the then 10-year-old dns Limited. This acquisition expanded SecureWorks' operation to include a UK-based operations center and additional offices in London and Edinburgh.

On January 4, 2011, Dell announced that it would acquire SecureWorks to be part of Dell Services. Dell SecureWorks officially began operating as a Dell subsidiary on February 7, 2011.

Dell SecureWorks continued to expand its portfolio around the world and in May 2013, it arrived in the ANZ region. The move to Australia and New Zealand put Dell in the ring of the security services market with companies like IBM, HP, and Verizon. Dell SecureWorks opened an operations center in Sydney to meet demands from local Australia businesses, the most in demand services in this area being Penetration Testing, forensic investigations and ongoing monitoring of environments for attacks.

On December 17, 2015, Dell subsidiary SecureWorks filed to go public.

On April 22, 2016, SecureWorks announced its IPO, raising $112 million after pricing its IPO at $14 per share. However, the company was expecting the initial price to be between $15.50-$17.50. This was the first tech IPO in the U.S. in 2016.
