Harness, the AI DevOps Platform™ company, announced the acquisition of Qwiet AI, formerly known as ShiftLeft, Inc., a leader in agentic AI-powered vulnerability detection and reachability analysis. Effective September 26, 2025, this acquisition builds on Harness’s March 2025 merger with Traceable and comes as the company’s application security business is projected to reach $50 million in ARR this year.
Closing the Security Gap in AI Code Generation
The pace of software development is accelerating rapidly, driven by AI-powered coding tools and innovative practices like “vibe coding,” which simplify the creation of complex code. However, this speed often comes at the expense of security. AI-generated code can inherit insecure patterns, omit essential safeguards, and introduce fabricated dependencies, resulting in hidden vulnerabilities. Security teams are increasingly overwhelmed with alerts many of which are false positives diverting attention from critical risks. As a result, enterprises face growing challenges in scaling AI development while maintaining compliance and robust security.
Harness and Qwiet AI: Reinventing Application Security for the AI Era
The integration of Qwiet AI strengthens Harness’s commitment to AI-era application security and its vision of a development landscape where speed and safety coexist.
“AI-generated code is transforming how software gets built, but it’s also introducing a new wave of hidden vulnerabilities,” said Jyoti Bansal, co-founder and CEO of Harness. “With Qwiet AI, we’re extending our robust application security portfolio to secure code from the very first step. By unifying security and DevOps, every build, test, and deployment can be secure by default – reducing risk while accelerating innovation. It’s a game-changer for enterprises that want to move fast and stay secure.”
Qwiet AI’s advanced Code Property Graph (CPG) technology is now integrated with Harness’s Software Delivery Knowledge Graph, powered by Harness AI. Along with Traceable runtime data, this combination delivers unparalleled application awareness and precision in vulnerability detection. By filtering out noise, developers can focus on critical risks while security teams prioritize strategic initiatives. Key benefits include:
-
Quiet alert noise: 97% true positive rate and 90% reduction in false positives ensure teams address real vulnerabilities only.
-
Reduce developer toil: Deep application awareness enables 95% faster remediation, helping developers fix issues efficiently.
-
Focus on what matters: Advanced reachability analysis prioritizes vulnerabilities that are actually exploitable, cutting through 92% of open-source alerts.
-
Understand real application risk: Insights from deep code understanding combined with production data help developers concentrate on threats that truly impact security.

“At Qwiet AI, we’ve always believed that developers deserve security that matches their speed,” said Stuart McClure, CEO of Qwiet AI. “Our technology was built for the future of AI-driven development, and Harness provides the platform and scale to bring that vision to life. Together, we can help enterprises turn security into a true driver of innovation.”
“With AI producing code at unprecedented speed, enterprises need security practices that can match the new pace of development,” added Katie Norton, Research Manager for DevSecOps at IDC. “This is accelerating demand for security testing built directly into DevOps platforms, where it can be adopted quickly, scaled easily, and managed without added integration burden. Harness’s acquisition of Qwiet AI reflects this shift and can help enterprises adopt AI-driven coding while ensuring innovation and security advance together.”
Expanding Security Leadership with Industry Expertise
To lead this next chapter, Rahul Sood joins Harness as General Manager. With extensive leadership experience at Palo Alto Networks, Google Cloud, Pindrop, and SAP, Sood will oversee the application security business and guide strategy as Harness continues building the most comprehensive AI DevSecOps platform in the industry.
“I’m excited to join Harness at such a pivotal time in the company’s growth,” said Rahul Sood, General Manager at Harness. “Application security is one of the most urgent challenges enterprises face in the AI era. Harness is uniquely positioned to meet developers where they are, baking security into the software delivery process so customers can innovate without compromise.”
Setting the Standard for Secure Software Delivery
The acquisition of Qwiet AI reinforces Harness’s end-to-end security portfolio, securing code from the first line to deployment across the entire SDLC. This milestone sets a new standard for enterprises seeking to deliver software with speed, resilience, and confidence.
