API security focuses on protecting APIs from malicious attacks, misuse, or unauthorized access, ensuring data confidentiality, integrity, and availability. With the proliferation of cloud-native applications, microservices, mobile apps, and IoT, APIs have become a central attack surface. The demand for API security solutions is growing rapidly as businesses accelerate digital transformation and cyber threats evolve in complexity.
The global application programming interface security market was valued at USD 523.4 million in 2023, growing at a CAGR of 31.2% from 2024 to 2033. The market is expected to reach USD 7909.9 million by 2033.
