How to Choose the Best API Security Platform
Choosing the correct API security platform is critical for protecting an organization's data and ensuring safe digital interactions.
Complete API Discovery and Inventory
An API security platform should automatically detect and update a list of all APIs, including shadow and undocumented ones. This ensures that no API endpoints go undetected, reducing weak spots in the organization's security posture. It should also allow to continuously identify new or old APIs in changing contexts.
Vulnerability Detection and Testing
Effective API security tools should perform detailed vulnerability checks that cover the OWASP API Top 10 vulnerabilities and more. They must identify problems like invalid authentication, data exposure, and injection attacks. Platforms should use AI and machine learning to identify both known and zero-day vulnerabilities.
Easy Integration
The best API security tools should integrate easily into existing development, with DevOps, CI/CD Pipelines, and deployment workflows. This allows continuous security testing that doesn't interrupt release cycles. Integrating with CI/CD pipelines allows automated scanning while building, testing, and deploying applications.
Risk Prioritization and Alerts
An API security platform must prioritize vulnerabilities based on their exploitable nature and business implications. It removes noise and reduces false positives, allowing security engineers to prioritize and address high-risk scenarios first. It should also send real-time alerts to quickly inform security and development teams about critical issues. Prioritizing insights helps speed up and improve remediation efforts.
Scalability and Support for Modern Architectures
Choose an API security platform that can scale with the growing and changing architecture of an organization. It should support the latest API standards, including REST, GraphQL, and gRPC. It should also accommodate microservices and serverless architecture. The API security platform must support cloud-based and SaaS-based platforms to improve flexibility and manageability.
Final Thoughts
Qualys is a popular platform used for managing vulnerabilities and provides many tools for finding assets, ensuring compliance, and scanning for security issues.
