Application Programming Interfaces (APIs) Security Testing Tools Market Global Report 2026

The application programming interfaces (APIs) security testing tools market size has grown exponentially in recent years. It will grow from $1.41 billion in 2025 to $1.89 billion in 2026 at a compound annual growth rate (CAGR) of 33.9%. The growth during the historic period was driven by increasing adoption of web and mobile applications, growing frequency of API-based cyberattacks, rising demand for secure software development practices, increasing cloud application deployment, and growing awareness of data privacy and protection requirements.

The application programming interfaces (APIs) security testing tools market size is expected to see exponential growth in the next few years. It will grow to $6.11 billion in 2030 at a compound annual growth rate (CAGR) of 34.2%. The growth during the forecast period is driven by rising adoption of API-first development approaches, increasing demand for automated security testing solutions, growing integration of AI-driven vulnerability detection, expanding usage of microservices architectures, and increasing regulatory compliance requirements for application security. Major trends during the forecast period include rising adoption of automated API vulnerability scanning solutions, increasing demand for continuous API security testing across software development lifecycles, growing integration of threat intelligence capabilities in API security testing tools, rising focus on authentication and authorization testing for APIs, and increasing demand for compliance-driven API security assessment solutions.

The growing frequency of cyberattacks is expected to drive the growth of the application programming interfaces (APIs) security testing tools market in the forecast period. A cyberattack refers to a deliberate attempt to compromise digital systems, disrupt operations, or gain unauthorized access to sensitive information by exploiting security vulnerabilities. Cyberattacks are increasing primarily due to rapid digital transformation, which has expanded the number of connected devices, applications, and potential vulnerabilities that malicious actors can exploit. API security testing tools help mitigate cyberattacks by detecting, assessing, and resolving API vulnerabilities before they are exploited, thereby improving application protection and supporting secure digital operations. For instance, in October 2025, according to the Australian Signals Directorate, an Australia-based government agency, during fiscal year (FY) 2024-25, the Australian Cyber Security Centre (ACSC) received more than 42,500 calls through the Australian Cyber Security Hotline, representing a 16% increase compared to the previous year. Therefore, the increasing frequency of cyberattacks is driving the growth of the application programming interfaces (APIs) security testing tools market.

Major companies operating in the application programming interfaces (APIs) security testing tools market are concentrating on the development of advanced solutions, such as deterministic API security policy enforcement, to provide consistent, automated, and tamper-resistant protection against API vulnerabilities and cyber threats. Deterministic API security policy enforcement refers to the implementation of predefined, rule-based API security controls that generate consistent allow or block decisions for identical requests. For instance, in June 2026, 42Crunch, a US-based API and AI security platform, partnered with GitHub Copilot, a US-based software development platform, to launch the 42Crunch API Security Testing Plugin for GitHub Copilot. The solution provides real-time detection, testing, remediation, and validation of API security vulnerabilities directly within AI-powered development environments. It evaluates OpenAPI specifications, detects OWASP API Security Top 10 risks, delivers AI-assisted remediation recommendations, and applies organizational security policies, enabling enterprises to securely expand agentic DevSecOps workflows and accelerate secure API development.

In November 2024, Snyk Ltd., a US-based cybersecurity company, acquired Probely for an undisclosed amount. Through this acquisition, Snyk Ltd. aims to enhance its developer-first security platform by integrating advanced DAST and API security testing capabilities, providing comprehensive, automated, and seamless application security solutions that enable secure AI adoption while balancing rapid innovation with strong security practices. Probely is a Portugal-based API security testing platform that provides application programming interface security testing tools.
