Edge Security Acceleration:API security overview

Last Updated:Oct 30, 2025

API security helps manage and protect APIs for your websites by leveraging sampled user access logs and built-in machine learning models. The system automatically scans associated APIs to detect potential threats and provides a management portal for monitoring and analysis.

Note

To enable the API security feature, contact your account manager.

Key features

Feature

Overview

API discovery

With machine learning and session identifiers, ESA automatically discovers the APIs for your website. You can evaluate and manage discovered APIs in API Security.

API management

ESA monitors your managed APIs to help you understand their performance and security status. The feature also offers rate limiting suggestions to protect your APIs from excessive traffic, enhancing overall security.

Schema validation

After you upload an API schema (such as an OpenAPI specification), the system automatically maps it to your managed APIs. It then validates incoming requests against this schema and applies your configured security policy to any non-compliant traffic.

API rules

Create API token validation rules by configuring JSON Web Token (JWT) validation policies and applying them to your managed APIs. ESA then validates incoming requests against these tokens to secure your business APIs.

Settings

API security settings enable centralized management of Session Identifiers, Schema Validation Settings, and Token Configurations.
