APIs are fundamental to the digital economy, serving as the bridge to modernize legacy apps, and the cornerstone of modern digital experiences. While APIs are subject to the same attacks that target web apps—namely exploits and abuse that lead to data breaches, account takeover, and downtime—API-based architectures introduce unforeseen risk from an ever-expanding plethora of third-party integrations and AI ecosystems.
F5 solutions secure APIs from code through testing into runtime across a burgeoning hybrid and multicloud digital fabric—reducing risk and complexity while improving operational efficiencies.

F5 solutions provide universal visibility, actionable insights, and highly-trained machine learning that continuously discovers and automatically defends critical business logic behind APIs.
F5 security employs a positive security model based on API schema learning, automated risk scoring, and ML-based protections.
F5 aligns API security to digital strategy and streamlines operations to accelerate app modernization from development to deployment and maintenance.
Learn about API security strategiesModernization is a business imperative. There is no other option. To succeed, you must streamline operations and align security to business strategy—differentiating from your competitors, meeting compliance requirements, and maintaining a resilient secure posture.
F5 API security reduces risk and complexity while improving operational efficiencies, so you maintain visibility and control across your entire digital ecosystem.
Learn how to address API security red flagsAddress modern application security challenges with dynamic API discovery, automated policy enforcement, and universal control across all apps and APIs powered by deep insights and machine learning.
Integrate your solution providers and tools to create an API‑driven security fabric.

Leaving any API unprotected is unwise. Every API request, regardless of its source, needs to be authenticated, authorized, and validated to reduce the risks of compromise.
