  • AI API security and integration assessment

Process

Four-Phase Project Delivery

How we run every engagement, from scoping to retesting

Scoping & Planning

We define objectives, rules of engagement, and success criteria together.

Execution & Analysis

Testing that combines our own tooling with manual analysis.

Reporting & Remediation

Detailed report with prioritized findings and step-by-step remediation guidance your team can act on.

Retesting & Verification

We retest your fixes to confirm they work and verify the security improvements.
