Methodology
Seven steps from discovery to remediation
Discovery Call
30-min conversation to understand your application, tech stack, business logic, and security concerns.
Scoping & Planning
We define the exact scope: which endpoints, components, dependencies, and configurations will be audited. You get a fixed quote.
Automated Scanning
SAST (Semgrep), SCA (Snyk, npm audit), CSP Evaluator, and custom scripts run against your codebase to catch low-hanging fruit.
Manual Code Review
Line-by-line examination of high-risk areas: authentication flows, data handling, third-party integrations, and privilege boundaries.
Report Generation
Findings ranked by CVSS severity with proof-of-concept examples and actionable remediation steps. Delivered as PDF + interactive dashboard.
Debrief Call
We walk through every finding together: the vulnerability, why it matters, and exactly how to fix it. No jargon, no surprises.
Remediation Support
Post-delivery email support to answer questions, review fixes, and ensure every vulnerability is properly resolved.
