Best IAST Tools

Checkmarx One is an application security software platform built to help enterprises secure every stage of the SDLC while reducing engineering costs and accelerating development. As a leader in agentic application security testing, Checkmarx scans trillions of lines of code each year, helping organizations cut vulnerability density by more than half. Its autonomous security agents detect, prioritize, and counter AI-driven threats across legacy, modern, and AI-generated code at enterprise scale.

Contrast Security provides an IAST platform that embeds agents into running applications, instrumenting code with sensors for real-time vulnerability detection and attack telemetry. Unlike external DAST scans or static SAST analysis, it analyzes data flows, application logic, and runtime behavior across development, CI/CD pipelines, and production. This reduces false positives by validating vulnerabilities in context, supports DevSecOps integration, and offers continuous monitoring for web apps, APIs, and microservices. Best for organizations prioritizing accurate, low-noise AppSec in agile environments over traditional black-box or white-box tools.

OpenText is a leading Cloud and AI company that provides organizations around the world with a comprehensive suite of Business AI, Business Clouds, and Business Technology.

HCL AppScan is an enterprise application security testing platform acquired from IBM in 2019. It provides integrated DAST, SAST, IAST, SCA, and API security testing across cloud and on-premises deployments. The platform serves large enterprises and regulated industries requiring federal compliance (FIPS 140-3 certified) and comprehensive governance. Best suited for organizations needing centralized application security orchestration with multi-scanner correlation and compliance reporting for PCI DSS, HIPAA, and GDPR.

Invicti Security combines DAST leaders Netsparker and Acunetix into a DAST-first ASPM platform for enterprise web application and API security. It uses proof-based validation via AcuSensor technology to confirm vulnerabilities like SQL injection and XSS with near-zero false positives. The platform correlates SAST, IAST, DAST, and SCA findings, providing runtime exploitability validation, code-level mapping to exact file/line, predictive risk scoring, and unified dashboards across testing tools. Best for DevSecOps teams needing accurate, automated scanning integrated with CI/CD workflows and compliance reporting for PCI DSS and SOC 2.

Snyk is an application security platform providing SAST (static code analysis), DAST (runtime testing), and SCA (software composition analysis) capabilities integrated into CI/CD pipelines. The vendor targets development teams seeking to embed security early in the SDLC, from first commit through production deployment. Snyk's AI-native approach uses machine learning to reduce false positives while detecting complex vulnerabilities across proprietary code, open-source dependencies, containers, and infrastructure.

Datadog is the leading observability and security platform for the AI era, providing businesses with unified visibility across the technology stack to manage complexity at scale.

Synopsys is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products.

Veracode is a cloud-native application security platform providing SAST, DAST, SCA, and runtime analysis capabilities. The vendor targets enterprise DevSecOps teams seeking to shift-left vulnerability detection into CI/CD pipelines. Veracode is positioned as the only native SaaS application security solution with industry-leading 1% false positive rates. Best suited for organizations requiring comprehensive code coverage across custom and third-party components with centralized policy management and developer-focused remediation workflows.
