Web Security

Web Application Security Testing

Threat-model-driven testing for production web applications and critical user flows

We map your trust boundaries, prioritize abuse paths around revenue and identity workflows, and validate exploitation manually so engineering teams can fix what matters first.

Engagement Duration

5-10 business days

Primary Outcome

A high-confidence vulnerability set with reproducible proof, business impact context, and concrete remediation steps your team can ship.

How This Engagement Works

Methodology + Threat Model

Human-led

We define scope, trust boundaries, and likely attacker goals for your exact environment.

AI Lead Generation

AI-assisted

Automation surfaces anomalous behavior, edge cases, and high-value paths worth manual attention.

Exploit Validation

Human-led

Every reported finding is manually reproduced and impact-tested before inclusion.

Remediation + Retest

Collaborative

We deliver developer-ready fixes and perform a free retest after your patch window.

Where AI Usually Finds Interesting Leads

01

Unusual state transitions in checkout, approval, or account recovery workflows

02

Hidden parameter combinations that unlock unauthorized actions

03

Privilege drift between API and frontend authorization checks

04

Session handling edge cases during role switching and concurrent usage

Core Exploitation Surface

We test baseline web attack classes and then pressure-test implementation details where real compromise usually appears.

Injection paths across web, API, and async job boundaries

Stored, reflected, and DOM XSS in high-value UI flows

Authentication/session weaknesses including takeover scenarios

Authorization bypass and vertical/horizontal privilege escalation

Business Logic and Abuse-Path Testing

This phase is intentionally creative: we model how motivated attackers chain low-friction flaws into meaningful business impact.

Workflow bypass in entitlement, approval, and pricing logic

State confusion and race conditions in multi-step transactions

Data integrity abuse with cross-account side effects

Multi-step chain attacks that begin from low-privileged users

Reporting and Retest

Severity-Ranked Findings

Each issue includes severity, exploitability notes, and expected impact if left unresolved.

Reproduction Playbook

Clear, stepwise reproduction instructions that developers and QA can execute reliably.

Practical Remediation Guidance

Fix recommendations focused on implementation reality, not generic best-practice lists.

Free Retest Confirmation

After patches are deployed, we retest and confirm closure status for reported findings.
