Runtime Application Security Testing
— API Runtime Security Testing
Manual validation and exploit-focused Runtime Application Security Testing. We help API Runtime Security Testing-based companies proactively secure their digital assets before attackers strike.
Free Scoping CallAPI Runtime Security Testing delivery and security model
Runtime testing for REST, GraphQL, and internal APIs across authorization, data leakage, rate limiting, and failure handling.
Focus areas
- Endpoint discovery and off-contract behavior
- Authorization bypass and object-level access
- Rate limits and resource consumption
- Error messages, logs, and data leakage
Delivery notes
- Every finding includes request and response evidence
- Abuse scenarios are tied to product workflows
- Remediation is assigned to gateway, service, or code layers
Decision matrix
API Runtime Security Testing is not just a service label; it states how each control is validated and which evidence is expected at closure.
| Control | Decision question | Validation | Expected evidence |
|---|---|---|---|
| Endpoint discovery and off-contract behavior | Does Endpoint discovery and off-contract behavior create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Runtime Application Security Testing. | Every finding includes request and response evidence |
| Authorization bypass and object-level access | Does Authorization bypass and object-level access create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Runtime Application Security Testing. | Abuse scenarios are tied to product workflows |
| Rate limits and resource consumption | Does Rate limits and resource consumption create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Runtime Application Security Testing. | Remediation is assigned to gateway, service, or code layers |
| Error messages, logs, and data leakage | Does Error messages, logs, and data leakage create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Runtime Application Security Testing. | Every finding includes request and response evidence |
What if Endpoint discovery and off-contract behavior fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Authorization bypass and object-level access fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.
What if Rate limits and resource consumption fails?
Eresus maps this area to real user-flow or delivery-pipeline impact, so the finding is not left as a generic technical label.

Frequently Asked Questions
What decision does API Runtime Security Testing clarify?
API Runtime Security Testing clarifies exploitability, affected workflows, and release impact for Runtime Application Security Testing with evidence rather than scanner noise.
What evidence is included in API Runtime Security Testing?
Every finding includes request and response evidence Also, Abuse scenarios are tied to product workflows. Retest criteria and ownership notes are included for closure.
How is this different from an automated scanner report?
Automated findings are not forwarded as-is; false positives are removed, abuse paths are proven, and remediation priority is explained.
