While a graduate student at Purdue University, Gene Kim, Tripwire’s co-founder and former chief technology officer, along with his professor, Gene Spafford, created the initial version of the software in 1992. This academic source release pioneered many techniques used in intrusion detection and received widespread support among corporate, education, and government security professionals.
In 1997, Gene Kim co-founded Tripwire, Inc. The rights to the Tripwire name and technology were attained, and a commercial version of the product, Tripwire for Servers was released soon thereafter. In 2000, Tripwire contributed source code functionally equivalent to the academic source release to the open source community to enable Open Source Tripwire.
In 2005, Tripwire released the first version of Tripwire Enterprise, the company’s flagship product designed to help organizations with IT configuration control by detecting, assessing, reporting and remediating file and configuration changes. In January 2010, Tripwire announced the release of Tripwire Log Center, log and security information and event management (SIEM) software that stores, correlates and reports log and security event data. The two products can be integrated to enable correlation of change and event data. August 21, 2009, Tripwire acquired Activeworx technologies from CrossTec Corporation. That includes Log Center, Security Center, Event Management, and Snort Management Center.
By May–June 2010, the company had over 5,500 customers. and had announced that it had filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of its common stock. A year later, the company announced its sale to the private equity firm Thoma Bravo LLC, ending its $86 million IPO plans. CEO Jim Johnson cited the firm's failure to reach the $100 million revenue milestone in 2010 as well as changing IPO market expectations as reasons for not going through with the IPO. The day following the acquisition, the company laid off about 50 of its 350 employees. Johnson expects the company will eventually go public, though it is unlikely to happen before 2015.
With the acquisition of nCircle in 2013, Tripwire added asset discovery and vulnerability management to its portfolio.  Tripwire IP360™ enables organizations to identify system vulnerabilities through advanced intelligence that prioritizes the most critical issues and how to fix them.

Tripwire laid off about 50 employees Tuesday — nearly 15 percent of its total work force — a day after the Portland network security company completed its sale to a private equity firm.But the layoffs would have happened regardless of that deal, according to Rekha Shenoy, Tripwire's vice president of marketing. Instead, she said, the company is "rightsizing" its work force to bring its headcount in line with industry peers.
