A proof of concept tests security and operational expectations in your own application, rather than simply demonstrating a product. Write the success criteria before testing begins.
Evaluation approach
Include at least one interference scenario, a legitimate-device matrix, performance measurements and outage behavior in the same assessment.
Application example
Ask the vendor to demonstrate that the protected operation did not occur on the server, rather than showing only an alert screen.
Limits and considerations
Success in one scenario cannot be generalized across the entire protection surface. The final report must state the tested scope.
From a trial to a purchasing decision
Writing acceptance criteria before the PoC prevents the best demonstration from defining the overall result. Include normal-device flows, service outages and rollback alongside critical attack scenarios. Assess each product using the same files and data conditions.
Distinguish documented features, observed behavior and unverified claims in the final report. A vendor's promise to fix an issue is not a substitute for the current result. Record the owner, target date and purchasing impact of every unresolved finding.
Technical assessment
An example acceptance table for your application
Define success before starting a PoC. A supplier demonstration and the effect on your own workflow are separate evidence.
| Area | Exercise | Evidence to retain |
|---|---|---|
| Normal use | Sign-in, sensitive action and logout | Task completion and user impact |
| Integrity | Controlled package changes in an authorized environment | Detection, enforcement and server outcome |
| Dependency failure | Verification-service outage | Safe restrictions and retries |
| Performance | Equivalent protected and baseline builds | Timing distributions by device and scenario |
| Operations | False-positive review and rollback | Sufficient context for support |
Record hashes, versions, settings and devices so later SDK releases remain comparable. An unperformed test is not a pass; state why it was outside coverage.
The decision can separate met requirements, known limitations and work required before production. Scores can support that structure but must not hide a critical gap behind low cost or quick integration.
Checks and decisions
- Write acceptance criteria in advance
- Collect reproducible evidence
- Measure rollback time
