It will grow to $6.07 billion in 2030 at a compound annual growth rate (CAGR) of 26.1%. The growth in the forecast period can be attributed to zero trust architecture adoption growth, expansion of microservices architecture, increasing api traffic volumes, rising compliance automation demand, growth in enterprise cybersecurity investments. Major trends in the forecast period include automated vulnerability detection tools, continuous security testing integration, DevSecOps pipeline adoption, cloud native API security expansion, real time threat monitoring.

The increasing frequency of cyberattacks is expected to drive the growth of the application programming interface (API) security testing tools market. Cyberattacks refer to deliberate attempts to damage, disrupt, or gain unauthorized access to digital systems, networks, or data. This rise in attacks is driven by greater digitalization, which creates more targets and opportunities for cybercriminals to exploit vulnerabilities. API security testing tools are essential in addressing these threats by identifying weaknesses and misconfigurations in APIs. They safeguard sensitive data by preventing unauthorized access, ensuring secure communication between applications, and strengthening overall cybersecurity measures. For instance, in July 2024, Check Point Software Technologies Ltd., an Israeli cybersecurity company, reported that corporate network cyberattacks had increased by 30% in the second quarter of 2024 compared to the same period in 2023, with a 25% rise from the first quarter of 2024. As a result, the growing incidence of cyberattacks is driving the demand for API security testing tools.

Major companies in the application programming interface (API) security testing tools market are concentrating on technological advancements, such as AI-driven API testing engines, to deliver more intelligent, scalable, and precise detection of runtime API vulnerabilities in modern, AI-enabled applications. AI-driven API testing engines are systems that utilize generative AI and machine-learning models to automatically identify, test, and simulate attack scenarios on APIs, with a particular focus on complex business logic risks like broken object-level authorization. For example, in April 2025, Snyk Inc., a US-based developer security platform, introduced Snyk API & Web, a next-generation dynamic application security testing (DAST) solution developed after integrating Probely’s technology. This solution features an AI-driven API testing engine that combines generative AI with traditional AI/ML models to map extensive API surfaces and automate the scanning of critical vulnerabilities. By incorporating this AI-driven engine into its DAST offering, Snyk enables developers and application security (AppSec) teams to proactively and accurately detect and remediate API vulnerabilities in complex system architectures.

In November 2024, Snyk Ltd., a US-based cybersecurity company, acquired Probely, a Portugal-based firm focused on API security testing tools, for an undisclosed sum. The acquisition is intended to strengthen Snyk’s developer-first security platform by incorporating advanced Dynamic Application Security Testing (DAST) and API security testing capabilities. This integration will provide comprehensive, automated, and seamless application security, facilitating trusted AI adoption while balancing rapid innovation with robust security measures.

Application programming interface (API) security testing tools are specialized software solutions designed to assess the security posture of APIs by detecting vulnerabilities, configuration issues, and potential threats. Their purpose is to protect APIs from attacks such as data breaches, injection vulnerabilities, and unauthorized access, helping to secure sensitive information and ensure safe communication between software systems.

The primary types of API security testing tools include static application security testing (SAST), dynamic application security testing (DAST), interactive application security testing (IAST), and runtime application self-protection (RASP). SAST is a white-box testing technique that examines an application’s source code or binaries for security flaws without executing the program. These tools can be deployed in both cloud and on-premises environments and are suitable for organizations of all sizes, including small and medium enterprises as well as large enterprises. They are used across various industries such as banking, financial services, and insurance (BFSI); healthcare; information technology and telecommunications; retail; government; and others.
