Web Application Pentesting

OWASP Top 10, business logic, auth flows and access control — tested by humans.

Overview

We test your application the way a motivated attacker would — but with your authorization. Automated tooling supports discovery; every real finding comes from manual analysis.

We focus on issues scanners miss: multi-step business logic, race conditions, privilege escalation between roles, and flawed trust boundaries.

What makes this engagement different

Manual testing discipline automation can't reproduce

Attack simulation grounded in how the app is meant to be used

Perspective checks across users, roles and tenants

Only verified, exploitation-proven findings

Aligned with industry standards

Our web assessments are anchored in the industry's most rigorous frameworks, so findings map directly to what your auditors and clients expect. Methodology follows OWASP WSTG and the OWASP Top 10, with coverage references to SANS CWE Top 25 and NIST guidance.

How the testing works

How we break into your web application, in four disciplines

Balanced automated + manual review

Automation covers the well-known surface quickly; everything hard-to-*find* then goes to a human who pulls components apart and reasons about them.

Full-spectrum vulnerability discovery

Battle-tested methodology mapped to OWASP Top 10 and beyond — logic abuse, chained weaknesses, trust-boundary mistakes.

Code-aware analysis at source level

When source is available, a high-level review of the codebase spots bugs, insecure patterns and standard violations before they ship.

Adversary-grade tooling and research

Internal attack tooling and lessons from thousands of app engagements keep your assessment aligned with what active adversaries use today.

Everything you need for compliance

Reporting templates map findings to the controls and sections auditors care about, so a single engagement feeds SOC 2 Type II evidence, ISO 27001 risk treatment, HIPAA or PCI-DSS reviews without extra paperwork.

Deliverables

Everything you receive, beyond the findings list

Pentest report

Comprehensive, navigable and written to be read — main body, per-finding detail, and screenshots.

Fix recommendations

Actionable remediation steps per finding, sized to effort where possible.

Shared Slack channel

Real-time collaboration with your team for questions, scope changes and urgent findings.

Free fix retesting

We retest deployed fixes to confirm they hold — included, not invoiced.

Attestation letter

A formal letter stating the test and its outcome, ready for clients and auditors.

Technical walkthrough

A debrief session for your engineering team to walk through the findings and priorities.

What we test

Injection flaws (SQL, NoSQL, command, SSTI)

Broken authentication & session management

Broken access control / IDOR / privilege escalation

XSS, CSRF, SSRF, open redirects, file upload abuse

Multi-step business logic & pricing flow abuse

Misconfigurations, debug artifacts, sensitive data exposure

Rate limiting & anti-automation controls

Third-party and API integrations

Attack scenarios we model

Scenario 01

An attacker escalates from a customer account to another tenant's data.

Scenario 02

Chained vulnerabilities: SSRF reaching, then metadata leak, then takeover.

Scenario 03

Malicious user manipulates checkout logic to get negative prices.

Scenario 04

Session tokens leak onto subdomains or third-party scripts.

What a finding looks like

criticalCVSS 9.1

Broken access control: sub-account IDOR leaks invoices

The endpoint /api/invoices/{accountId} accepted any numeric accountId for logged-in users, returning other tenants' invoice PDFs. Automated enumeration harvested all invoices in under an hour.

Remediation

Enforce server-side ownership checks on accountId; add authorization tests to CI; audit sibling endpoints for the same pattern.

Staying ahead of the latest hacking techniques

Our testers continuously study emerging attacker techniques, so the tests include vulnerabilities that haven't yet landed in public frameworks.

  • Simulate the ingenuity of a real attacker
  • Leverage fresh attacker tactics and tooling
  • Test emerging threats, e.g. new critical CVEs
  • Focus on high-impact weaknesses
