Akamai uses machine learning in its API Security product to automatically discover undocumented APIs across a customer's infrastructure and detect anomalous or malicious API traffic in real time. The product has been generally available and receives ongoing updates; a Q4 2024 update enhanced threat-blocking capabilities.

API Security uses machine learning-fueled detection to identify API vulnerabilities, shadow APIs (undocumented endpoints), and attacks including those listed in the OWASP API Top 10. It continuously monitors API behavior, learns normal usage patterns, and flags deviations such as unusual request rates, unexpected endpoint access, or suspicious payloads. In 2025, Akamai added API LLM Discovery to automatically discover and tag AI-related API endpoints, including those connected to LLMs and Model Context Protocol servers.
