Qwiet AI (formerly ShiftLeft CORE) was an AI-powered application security platform that combined next-generation SAST, intelligent SCA , and secrets detection into a unified developer experience. Harness acquired Qwiet AI in September 2025 , and the technology now ships inside Harness Security Testing Orchestration (STO).
The platform used Code Property Graph (CPG) technology to perform reachability analysis, helping teams focus on vulnerabilities that actually mattered in their codebase. The same engine powers Harness STO today.
Where Qwiet AI fits today (post-Harness acquisition)
As of 2026, the standalone Qwiet AI product is no longer sold to net-new customers.
Existing Qwiet AI customers were migrated onto Harness STO, which combines the CPG-based reachability analysis with Harness’s broader DevOps platform (CI, CD, feature flags, cloud cost). New buyers evaluating Qwiet AI today should evaluate Harness STO directly.
If you arrived here looking for standalone reachability-driven SCA that is not bundled with a DevOps suite, the alternatives section below covers the closest active replacements.
What Qwiet AI did
Qwiet AI took a different approach to application security by analyzing code as a graph structure rather than pattern matching. The platform built a Code Property Graph that represented the relationships between code elements, enabling data flow analysis to determine whether vulnerabilities in dependencies were actually reachable from application code.
This approach reduced false positives and noise, letting development teams focus remediation on issues that posed genuine security risk. The platform integrated SAST, SCA, and secrets detection into a single scan, removing the overhead of managing multiple tools.
Capabilities (historical)
Reachability analysis
The standout capability of Qwiet AI was its AI-powered reachability analysis. Rather than flagging every known vulnerability in a dependency tree, the platform traced data flows to determine which vulnerabilities could actually be triggered by application code. The vendor claimed an 85-95% reduction in actionable findings compared to traditional SCA tools — a reachability story Harness now markets under the STO brand.
Code Property Graph technology
Qwiet AI constructed a semantic graph representation of the codebase that captured abstract syntax trees, control flow, and data flow in a unified structure. This enabled analysis that understood how data moved through an application, identifying complex vulnerability chains that pattern-based tools missed.
Fast scan performance
The platform was engineered for CI/CD integration with scan times measured in minutes rather than hours. Incremental scanning focused on changed code, enabling rapid feedback loops during development. Full scans of large enterprise codebases completed quickly enough to run on every pull request.
Developer-centric remediation
When vulnerabilities were identified, Qwiet AI provided contextual remediation guidance that showed exactly where the issue occurred in code. The platform explained the attack path, demonstrated how the vulnerability could be exploited, and suggested specific fixes tailored to the implementation.
Where to evaluate now
The Qwiet AI / ShiftLeft CLI (sl analyze, cdn.shiftleft.io) is no longer the active onboarding path — those CLI endpoints are legacy and the install workflow has been replaced. Net-new buyers should evaluate Harness STO
directly. Existing Qwiet AI / ShiftLeft customers should follow Harness’s migration guide rather than running the legacy sl binary against new projects.
If you specifically need standalone, reachability-driven SCA without bundling a full DevOps suite, the alternatives below cover the closest active replacements.
Active alternatives
- Snyk Open Source — Reachability analysis for SCA with SaaS and CLI workflows. Closest like-for-like for teams that want a standalone product.
- Endor Labs — Function-level reachability and dependency lifecycle analytics. Strongest narrative for noise-reduction in 2026.
- Semgrep Supply Chain — CPG-flavoured reachability built on Semgrep’s static analysis engine; competitive on price.
- Apiiro — Risk Graph that adds runtime and ownership context on top of any existing SCA. Better fit if you already own scanners.
- Aikido — Bundled SAST + SCA + secrets with reachability triage. Better fit for SMB / mid-market teams that want one platform.
History
Originally launched as ShiftLeft CORE, the company rebranded to Qwiet AI in 2023 to better reflect its AI-powered approach to application security. The rebrand accompanied platform enhancements to reachability analysis and expanded language support.
Harness acquired Qwiet AI in September 2025 and integrated the CPG engine into Harness Security Testing Orchestration (STO). The standalone Qwiet AI product reached end-of-sale shortly after the acquisition.
