Best API Security Software

Compare the Top API Security Software as of April 2025

What is 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 API Security software currently available using the table below. This list is updated regularly.

    Quantum Armor

    Silent Breach

    Your attack surface is the sum of every attack vector that can be used to breach your perimeter defenses. In other words, it is the total quantity of information you are exposing to the outside world. Typically, the larger the attack surface, the more opportunities hackers will have to find a weak link which they can then exploit to breach your network. Professional hackers typically follow the cyber kill chain when attacking a target, and surveying the target's attack surface is normally the very first step in this process; what is known as advanced reconnaissance. Reducing the attack surface can minimize risk further down the cyber kill chain, preventing attacks before they even occur by eliminating potential attack vectors as early as possible. The cyber kill chain is a method of categorizing and tracking the various stages of a cyberattack from the early reconnaissance stages to the exfiltration of data.

    Spherical Defense is an API security solution that uses deep unsupervised learning to protect your APIs. Spherical Defense Express is deployed on AWS, takes just a minute to download and will be protecting your assets within two hours at the cost of $1 per hour. Once you have deployed your Spherical instance, it will immediately start listening for API traffic. It will stay in this mode for only as long as there is insufficient data to train the first security model. After receiving roughly 16,000 requests, it will move to the next stage. After sufficient data has been received, the system moves into training mode. This mode will result in a trained security model after roughly 6 hours, which will then be mounted for evaluation. As new data is received, the Spherical instance will train more models to account for natural changes in your API traffic over time. Once the first security model has been trained, it is mounted for evaluation.
