Checkmarx One SAST is a static application security testing solution that scans source code to identify security vulnerabilities in applications. The platform combines speed and security, offering up to 90% faster scanning with 80% lower false positives compared to traditional SAST tools. It features adaptive vulnerability scanning that can quickly find relevant results or perform deep analysis for mission-critical applications. The tool scans uncompiled code directly from source code repositories on check-in, integrating into the SDLC without requiring code compilation. It supports over 35 programming languages and 80 language frameworks, covering both modern and legacy codebases for multi-platform development. The platform includes AI-powered capabilities such as an AI Query Builder that uses generative AI to create and customize queries for improved fidelity, and an AI Security Champion that provides auto-remediation recommendations with code fixes. Best Fix Location functionality identifies the root cause of vulnerabilities to enable fixing multiple issues at once. The solution integrates directly into developer environments and supports incremental scanning of only changed code to reduce scan times. It provides analytics dashboards for holistic AppSec posture management, vulnerability triage, and remediation tracking across the application portfolio.
