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

- 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.”

FAQs
Our solution is critical for maintaining compliance. We actively support frameworks including PCI-DSS v4.0, GDPR, and ISO 27001. We also have DORA on our 2026 roadmap.
Yes. We support all deployment models, including SaaS, On-prem, Hybrid, and fully air-gapped environments. Crucially, you get the exact same UI and feature set across all models.
We do both, and the choice depends on your needs. Our agentless scanning provides powerful detection. For real-time blocking, we use our Gateway Integration (e.g., with F5, Kong, Nginx) to stop attacks before they reach your application.
Our solution primarily supports REST APIs. We also discover and inventory APIs by integrating with API gateways, controllers, and service mesh sidecars (like Envoy).
When we discover a “Zombie API” (a deprecated version still in use) or another finding, we log it in the central catalog. From there, administrators can manage the finding’s status, change its severity, and create a ticket directly in an integrated system like Jira or ServiceNow.
We use two primary methods: Gateway Integration and Agentless Scanning. We find this approach provides comprehensive discovery without the high overhead and false positives associated with traditional traffic analysis.
Yes. Our platform supports integration with OIDC providers and other authentication and authorization standards to secure your API ecosystem.
We support over 80 integrations right out of the box. This includes major SIEMs like Splunk, Elastic, QRadar, and Sentinel, as well as ticketing systems like Jira, ServiceNow, and FreshService.

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.
