APPLICATION SECURITY

Web & API Security Audits

Identify and understand security issues in your web application, API, or authentication flows before they become operational problems.

What I assess

Engagement scope can include authenticated and unauthenticated application routes, API endpoints, session management, access controls, OAuth-related flows, security headers, and infrastructure-facing application configurations. Testing is performed only with authorization and within agreed boundaries.

How the engagement works

We agree on scope, systems, access, constraints, and reporting requirements. I document reproducible findings, explain the business and technical impact, and prioritize remediation. A follow-up review can validate fixes when included in the project scope.

What you receive

The intended deliverable is a concise, actionable report: affected component, reproduction steps, evidence, severity with a stated scoring basis, recommended fix, and validation guidance. Results depend on what is actually observed; an audit never guarantees a system is free of vulnerabilities.

Frequently asked questions

What is included in a web or API security assessment?

A scoped review may cover authentication, authorization, sessions, OAuth flows, API behavior, input handling, security headers and relevant application configuration.

Do you perform security testing without authorization?

No. Testing is performed only against targets, accounts and environments that the system owner has explicitly authorized within an agreed scope.

What do I receive after the assessment?

You receive an actionable report with affected components, reproducible evidence, impact, severity context, recommended fixes and validation guidance.
