The Top 5 API Security Providers To Consider in 2025

The Growing Importance of API Security

API security refers to the practices, tools, and strategies in place to protect Application Programming Interfaces. As APIs grow in importance, so does API security. Organizations need proactive security controls in place to ensure the data and services provided by APIs remain protected.

Misconfigured or poorly secured APIs provide an easy entry point for threat actors looking to breach your system and gain unauthorized access. The importance of API security is reflected by the Open Worldwide Application Security Project (OWASP) choosing to compile a list of the most impactful API vulnerabilities. The latest top 10 list of API vulnerabilities can be found here.

Falling victim to an API attack can lead to dire consequences, including:

• The exposure of sensitive data.
• Non-compliance with data privacy regulations.
• Disruptions to your business services.
• Significant Reputational damage.
• Financial losses from remediating the attack and loss of business.

API security is the only thing stopping this, and API security platforms are the best tool you have to help, so it is vital to know what to look for.

Top 5 API Security Providers

#1. Check Point

CloudGuard WAF from Check Point offers extensive real-time API security features, including AI-powered threat detection to protect against known and unknown threats.

Other security features include built-in DDoS prevention and the ability to create and enforce custom API security policies.

Pros:

• AI analysis improves API threat detection accuracy by analyzing user behavior and identifying activity that deviates from the norm.
• Behavior-based threat detection simplifies enforcement, removing the need for updates based on the latest signatures.
• Automated API discovery for a comprehensive understanding of your API landscape.
• Custom deployments and security policies tailored to the specific needs of your organization.

Cons:

• • With a wide range of deployment options, some users may find configuring the solution complicated.

• Using behavior-based threat detection introduces a small number of false positives.

#2. Imperva

Imperva’s API Security platform is part of the company’s broader suite of application security tools.
