Automatically identifies known vulnerabilities in third-party libraries and open-source dependencies, ensuring the entire "software supply chain" is secure.

By utilizing instrumentation, it solves the two biggest headaches in AppSec: false positives and context switching. For organizations struggling to secure modern, complex architectures (microservices, cloud-native apps) without slowing down their release cadence, OneAST offers a solution that speaks the language of developers while providing the assurance security teams require.

aims to end this cycle. It represents a paradigm shift from scanning code to observing code.

Contrast Security’s OneAST is not just another scanner. It is a .

| Aspect | Contrast AST (Legacy) | Contrast Security One | |--------|----------------------|------------------------| | | Self-managed (on-prem) or single-tenant cloud | Fully managed SaaS (multi-tenant) | | Core Technology | IAST + SAST + SCA (separate sensors) | Unified agent (IAST + RASP + SCA + API Security) | | Analytics | Basic correlation | AI-driven analytics + automated attack validation | | Policy & Remediation | Manual rules, fixed policies | Dynamic risk scoring, prioritized fix guidance | | Scalability | Limited by self-hosted infrastructure | Auto-scaling, zero-ops |

Developers build software, and then—often days or weeks later—a separate security team runs a scan, finds a laundry list of vulnerabilities, and throws it back over the wall. This "stop-and-fix" model is the primary friction point in modern software delivery.

Security teams no longer need to correlate a SAST report (which says "Line 50 is risky") with a DAST report (which says "The login page is vulnerable"). OneAST combines these, telling the developer: "The vulnerable library Log4j is being actively exploited on line 50 of the Login Controller."
