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

We Bring you the Security
API Security FAQs
We use service mesh sidecars and eBPF to inspect actual API behavior, detect anomalies, and identify shadow/zombie/orphan APIs. Plus, we deliver access policy enforcement and multi-vector visibility (process, file, network, API) that WAFs can’t provide. WAFs guard the front door—AccuKnox secures every conversation inside your house.
Policies are enforced through runtime instrumentation that intercepts API calls, validates schemas, applies rate limiting, and blocks threats in real-time. Deploy enterprise-grade API security in hours, not months, with zero refactoring.

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.
