Uncover & Neutralize Vulnerabilities in Your APIs with AccuKnox's API Discovery, Inventory, and Cataloging
Here’s Why You Need API Security
- Lack of comprehensive API visibility, leading to security blind spots.
- Shadow and zombie APIs expose organizations to hidden attack surfaces.
- Weak API access controls undermine Zero Trust principles and AI/ML security.
- Threats like injection attacks and OWASP Top 10 API vulnerabilities remain a significant risk.
AI-enhanced attacks top the list of the biggest percieved threats to API security today, followed by unauthorized access/breaches and insufficient data protection/encryption

API Discovery, Inventory & Cataloging – Zero Trust Way
Runtime API Security
- Uses service mesh sidecars or proxies to inspect secure traffic and detect anomalies.
- Exports API instrumentation data in OpenTelemetry format for seamless monitoring.
- Identifies access patterns with a discovery engine and provides a SaaS or on-prem control plane for management.
- Identifying sensitive data assets in API headers, responses
Static API Security
- Scans code repositories and analyzes API specs (OpenAPI, Swagger, WSDL) for security gaps.
- Extracts endpoint details, peer connections, and access requirements for better enforcement.
- Integrates into CI/CD pipelines to detect and mitigate risks before deployment.
API Security Testing
- Identify vulnerabilities including OWASP Top 10 for API.
- Detects and mitigates injection attacks, broken authentication, and other critical threats.
- Identifying Shadow, Zombie, and Orphan APIs

Enterprise Grade API Security Use Cases
API Discovery & Traffic Analysis
- Discover service-to-service communication, shadow/zombie APIs, and internal/external API access using platform abstractions (e.g., Kubernetes).
- Capture and inspect traffic metadata for empirical analysis and compliance.
API Performance & Monitoring
- Track API access metrics (latency, success rate)
- Protect against OWASP Web & API attacks using traffic signatures.
- Mapping API specifications to real env time traffic
DoS Attack & TLS Security
- Detect and mitigate DoS attacks early with eBPF XDP.
- Identify TLS/certificate misconfigurations and manage secure connections with tools like “k8tls.”
Authentication & Sensitive Data Protection
- Identify brute force authentication attempts and detect sensitive data exposure in API responses.
API Security Testing
- Identify vulnerabilities per OWASP Top 10 for API and common injection attacks.
- OpenAPI/Swagger-based scans for vulnerability detection.
- LLM assisted validation to detect secrets and unsecured endpoints.
Harden APIs with schema validation, authZ/OPA enforcement, rate limiting, and anomaly detection from runtime telemetry.

API Security Platform: Complete Guide
Guide Topics
APIs drive modern apps—but they also create new risks. Explore how AccuKnox helps you secure every API across your cloud-native environment with deep visibility, behaviour-based enforcement, and Zero Trust runtime protection.
What is API Security?
API Security is the practice of protecting APIs from misuse, abuse, and attacks—whether they’re public-facing, internal, or third-party integrated. As APIs become central to application architecture, attackers are increasingly targeting them to gain unauthorised access, exfiltrate data, or disrupt services.
AccuKnox helps you go beyond traditional scanning by securing APIs at runtime—monitoring behaviour, enforcing access controls, and detecting threats as they happen.
Why API Security Matters Now
APIs are growing faster than they’re being secured. Modern DevOps pipelines often expose:
- Shadow APIs that are undocumented and unmonitored
- Broken access controls or over-permissioned endpoints
- Insecure third-party integrations
- Lack of audit trails and runtime enforcement
These challenges lead to API data breaches, lateral movement, and compliance violations. AccuKnox brings clarity and protection by enforcing Zero Trust at the API layer—detecting misuse and controlling behaviour dynamically.
AccuKnox API Security: Key Capabilities
✅ API Discovery & Inventory
Continuously detect known, unknown, and shadow APIs across Kubernetes, containers, and microservices.
✅ Runtime API Monitoring
Analyse traffic behaviour, usage patterns, and anomalies—mapped to users, services, and namespaces.
✅ Access Control & Enforcement
Apply least-privilege policies to control which services or roles can access which APIs—and how.
✅ Zero Trust Runtime Protection
Block unauthorised API access and abnormal behaviour using KubeArmor and eBPF-based controls.
✅ Threat Detection & OWASP Coverage
Detect OWASP API Top 10 attacks like injection, broken authentication, and data exposure in real time.
