Compare the Top On-Premises API Security Software as of April 2025

What is On-Premises API Security Software?

API security software is designed to protect APIs from security threats such as unauthorized access, data breaches, and denial-of-service attacks. These tools monitor, authenticate, and secure the connections between APIs and the systems they interact with, ensuring that only authorized users and systems can access the data or services offered by the API. Features typically include encryption, rate limiting, authentication (such as OAuth, JWT), API traffic monitoring, threat detection, and automated security testing. API security software is crucial for businesses that rely on APIs to connect with third-party services, mobile apps, or microservices, as it helps mitigate risks and maintain data integrity. Compare and read user reviews of the best On-Premises API Security software currently available using the table below. This list is updated regularly.
