It will grow from $1.5 billion in 2024 to $1.9 billion in 2025 at a compound annual growth rate (CAGR) of 26.6%. The growth during the historic period can be attributed to the rising demand for digital transformation, increased reliance on cloud-based services, the widespread adoption of microservices architecture, a stronger emphasis on improving customer experiences, and the growing significance of data-driven decision-making.

The application programming interface (API) security testing tools market size is expected to see exponential growth in the next few years. It will grow to $4.81 billion in 2029 at a compound annual growth rate (CAGR) of 26.2%. The growth expected in the forecast period is driven by the expanding use of Internet of Things (IoT) devices, a stronger focus on expanding partner ecosystems, increasing demand for application interoperability, heightened regulatory compliance and security needs, and the rising adoption of open banking and fintech solutions. Key trends during this period include the integration of cloud computing platforms, progress in microservices architecture, innovations in mobile and web applications, incorporation of real-time data analytics, and advancements in artificial intelligence and machine learning integration.

The rising frequency of cyberattacks is anticipated to drive the expansion of the application programming interface (API) security testing tools market. Cyberattacks involve intentional efforts to harm, interrupt, or gain unauthorized entry into digital systems, networks, or data. The surge in such attacks is fueled by increased digitalization, which creates more targets and opportunities for cybercriminals to exploit vulnerabilities. API security testing tools play a crucial role in combating these attacks by detecting weaknesses and misconfigurations in APIs. These tools protect sensitive information by blocking unauthorized access, ensuring secure communication between applications, and enhancing overall cybersecurity measures. For example, Check Point Software Technologies Ltd., an Israeli cybersecurity firm, reported in July 2024 that corporate network cyberattacks had risen by 30% in the second quarter of 2024 compared to the same period in 2023, with a 25% increase from the first quarter of 2024. Consequently, the growing number of cyberattacks is fueling the demand for API security testing tools.

Leading companies in the API security testing tools market are focusing on innovations such as custom scan discovery to improve the detection of API vulnerabilities and bolster cybersecurity defenses. Custom scan discovery is a feature that enables security tools to automatically locate, map, and assess all existing and newly added APIs within an environment, facilitating targeted and thorough vulnerability assessments. For instance, in September 2022, StackHawk Inc., a software company based in the US, introduced Deeper API Security Test Coverage. This solution allows developers to conduct deeper, faster, and more comprehensive security testing across the entire API layer, addressing vulnerabilities often missed by traditional tools. It incorporates custom scan discovery and seamlessly integrates with developer workflows, using realistic test data and custom scripts to identify issues such as broken authorization and exposure of sensitive data. This technology helps organizations confidently launch secure APIs by automating extensive testing early and throughout the software development lifecycle, effectively minimizing security risks.

In November 2024, Snyk Ltd., a cybersecurity company headquartered in the US, acquired Probely, a Portugal-based firm specializing in API security testing tools, for an undisclosed amount. This acquisition aims to enhance Snyk’s developer-first security platform by adding advanced Dynamic Application Security Testing (DAST) and API security testing capabilities. The integration will offer comprehensive, automated, and seamless application security, supporting trusted AI adoption while balancing rapid innovation with strong security measures.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.

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.
