Four-Phase Project Process

Close collaboration throughout the engagement

1. Scoping & Planning

A collaborative phase to define clear objectives, rules of engagement, and success criteria for the project.

2. Execution & Analysis

Hands-on execution combining advanced tools with deep manual analysis.

3. Reporting & Remediation

Delivery of a comprehensive report with prioritized findings and clear, step-by-step remediation guidance designed for immediate action.

4. Retesting & Verification

All implemented fixes are retested to confirm their effectiveness and verify security improvements.
