API Security
APIs are the backbone of modern systems, connecting applications, services, and data across platforms. Vulnerabilities in APIs can lead to unauthorized access, data breaches, and serious security risks. At Crystalline, we specialize in providing comprehensive API Security Assessments to identify potential security flaws, ensuring that your APIs remain secure, resilient, and compliant with industry regulations. Our expert team uses industry-leading tools and manual testing techniques to evaluate the security of your APIs and provide actionable recommendations to mitigate risk.
"Secure Your APIs Against Vulnerabilities and Attacks"

Why API Security is Critical?

Our API Security Process
Initial Scoping
We begin by discussing the scope of your APIs and the business functions they support. This helps us understand the critical areas that need to be assessed, such as user authentication, data access, and third-party integrations.
Vulnerability Scanning
We conduct automated vulnerability scans on your APIs to detect common flaws, such as Broken authentication or weak session management, Input validation vulnerabilities (e.g., SQL injection, XSS), Insufficient rate-limiting and DoS attacks and Sensitive data exposure in responses.
Access Control
We thoroughly test the strength of your API’s authentication (e.g., OAuth, API keys) and authorization controls, ensuring that unauthorized users cannot gain access to restricted resources.
Reporting
We provide a comprehensive report detailing our findings, including vulnerabilities, their severity, and the potential business impact. Each vulnerability is followed by actionable recommendations for remediation.
Information gathering
Our team gathers publicly available information about your APIs and the systems they interact with. We identify endpoints, API routes, methods, data formats, and other critical components to map out potential attack surfaces.
Manual Testing
Our experts manually test the APIs, simulating real-world attacks. This includes testing for vulnerabilities such as business logic flaws or improper API design. We attempt to exploit these weaknesses to assess their potential impact.
Error Handling
We assess how your API handles invalid requests, errors, and failed authentications, ensuring that error messages do not expose sensitive system information that could be used by attackers.
Retesting
Once vulnerabilities are fixed, we conduct retesting to ensure that the fixes are effective and no new issues have been introduced. We also ensure that your APIs meet security best practices.
