Application Security Testing
— Data Flow and Taint Analysis
Manual validation and exploit-focused Application Security Testing. We help Data Flow and Taint Analysis-based companies proactively secure their digital assets before attackers strike.
Free Scoping CallData Flow and Taint Analysis delivery and security model
Deep code analysis that follows user-controlled input from sources into databases, file systems, command execution, templates, and external service calls.
Focus areas
- Input sources and trust boundaries
- SQL, command, template, and file sinks
- Missing validation and encoding steps
- Cross-layer data-flow breaks
Delivery notes
- Every finding shows the source-to-sink path
- False positives are filtered by realistic execution paths
- Remediation points to validation and encoding locations
Decision matrix
Data Flow and Taint Analysis 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 |
|---|---|---|---|
| Input sources and trust boundaries | Does Input sources and trust boundaries create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Every finding shows the source-to-sink path |
| SQL, command, template, and file sinks | Does SQL, command, template, and file sinks create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | False positives are filtered by realistic execution paths |
| Missing validation and encoding steps | Does Missing validation and encoding steps create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Remediation points to validation and encoding locations |
| Cross-layer data-flow breaks | Does Cross-layer data-flow breaks create real risk? | Validated against the relevant code, request, configuration, or runtime behavior in Application Security Testing. | Every finding shows the source-to-sink path |
What if Input sources and trust boundaries 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 Data Flow and Taint Analysis clarify?
Data Flow and Taint Analysis clarifies exploitability, affected workflows, and release impact for Application Security Testing with evidence rather than scanner noise.
What evidence is included in Data Flow and Taint Analysis?
Every finding shows the source-to-sink path Also, False positives are filtered by realistic execution paths. 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.
