End-to-End API Protection

Discover APIs Wherever They Run

Discover and catalog your APIs across any environment, including containers, VMs, and hybrid deployments. Automatically detect APIs regardless of configuration or type, eliminating blind spots and providing complete coverage across your infrastructure.

Support Any API Protocol

Natively support a wide range of protocols including RESTful, HTTP, HTTPS, GraphQL, SOAP, and more. Automate the creation of a comprehensive API catalog that spans every protocol, capturing both legacy and modern standards. This protocol-agnostic approach ensures consistent monitoring, documentation, and security enforcement across your entire API landscape.

Dynamically Catalog API Schemas

Continuously analyze requests and responses to automatically generate and update API schemas in real time. Get an accurate and always up-to-date view of your APIs, complete with rich context around resources, endpoints, and data flows. By maintaining a living schema, you can better understand how APIs evolve, detect drift, and ensure consistency across services.

Classify Sensitive Data in Motion

Identify and classify sensitive data such as PII, PHI, and PCI as it traverses your APIs. Track data lineage with precision, providing clear visibility into how sensitive information is collected, transmitted, and stored. Ensure stronger compliance with regulatory standards while reducing the risk of accidental exposure or misuse of sensitive data within API traffic.

Detect & Stop API Threats

Continuously monitor API traffic to detect and block threats at Layer 7. Leverage activity analysis to identify anomalies, misuse, and malicious patterns in real time. Integrate with automation workflows to streamline response and remediation, ensuring threats are neutralized before they impact your applications or data. This proactive approach protects APIs from both known and emerging attack vectors.

Test APIs with DAST for Vulnerabilities

Proactively test APIs in runtime with Dynamic Application Security Testing (DAST) to uncover vulnerabilities as they appear in real traffic. Observe live requests, parameters, authentication flows, and responses to identify issues such as broken authentication, authorization failures, and sensitive data exposure. Focus on addressing the most critical risks, reducing exposure windows, and maintaining a strong API security posture without slowing down development.

Upwind’s testing for API vulnerabilities has been instrumental in our API security practice. We’ve been able to proactively identify exposed endpoints and data flows, providing us with increased visibility in to our API landscape. Upwind’s runtime-centric approach to securing APIs has helped us prioritize real risks and reduce our attack surface without slowing down development.

Upwind’s ability to provide detailed API insights shined the light on areas where we could proactively reduce our attack surface, that previously we had no visibility into. Doing so not only allowed us to harden our security, but to also act with increased precision and speed to reduce potential risks.
