Manual Testing Where It Matters

Burp + brain, not just Burp

Why Most Web App Tests Miss the Real Bugs

Modern web apps are no longer about classic SQL injection. The vulnerabilities that take down companies in 2026 are IDORs in tenant-isolation logic, JWT and OAuth misconfigurations, race conditions in checkout flows, server-side request forgery into cloud metadata, and chained authorization bypasses. None of those are found by a DAST tool — they require an operator who understands your application as well as your engineers do.

What We Test For

Coverage that matches the OWASP Top 10 and goes well beyond

Authentication & Session

Credential stuffing, password reset abuse, MFA bypass, SSO/SAML/OIDC flaws, JWT and OAuth misconfigurations, session fixation, and persistent-cookie attacks.

Authorization (IDOR / BOLA)

Broken object-level authorization, tenant-isolation bypasses, horizontal and vertical privilege escalation, function-level access control, and admin-route exposure.

Injection & Deserialization

SQL, NoSQL, LDAP, OS command, template (SSTI), and XXE injection. Unsafe deserialization in Java, .NET, Python, Ruby, and Node.js.

Client-Side & XSS

Reflected, stored, and DOM-based XSS; CSP bypasses; postMessage abuse; clickjacking; prototype pollution; and modern SPA-framework sinks (React, Vue, Angular).

SSRF & Server-Side

Server-side request forgery, blind SSRF into cloud metadata (IMDSv1/v2), open redirect chaining, request smuggling, and HTTP/2 desync attacks.

Business Logic Abuse

Race conditions in checkout and refund flows, coupon/promo abuse, workflow skipping, mass-assignment, file-upload abuse, and idempotency-key replay.

Our Methodology

OWASP-aligned, source-assisted, and reproducible

1

Scoping & Threat Modeling

Application walkthrough with your engineers, role/tenant matrix, and a STRIDE-based threat model of the surfaces most worth attacking.

2

Mapping & Discovery

Spidering, content discovery, parameter mining, JS-bundle analysis, and full request/response cataloging. We learn your app before we attack it.

3

Automated Foundation

Authenticated DAST + dependency scanning gives us a baseline. We never report scanner output as findings — it's just the floor.

4

Manual Exploitation

Where the real value is. Auth, IDOR, business-logic, and chained vulnerability discovery by senior operators. Every finding gets a working PoC.

5

Reporting

Executive summary + CVSS-scored technical findings + recommended code-level fixes. We write reports your engineers can hand to a sprint planner without translation.

6

Re-Test & Sign-Off

Free re-test of every fixed finding within 90 days. We sign off remediation in writing — useful for compliance and for your customers' security questionnaires.

Web application security testing

Senior Operators, Not Tool Operators

OSCP, OSWE, GWAPT, and Burp Suite Certified Practitioner. Every consultant has shipped production web applications, so we understand the engineering tradeoffs behind the vulnerabilities we find.

Compliance-Ready Deliverables

Reports formatted for PCI DSS 6.4.7, SOC 2 CC7.1, HIPAA 164.308(a)(8), and customer-facing security questionnaires. One test, many compliance check-marks.

Free Re-Testing

90-day remediation re-test is included with every engagement. You don't pay twice to prove the fix worked.

Tight With AppSec & DevSecOps

Findings are delivered as actionable backlog items — we cross-link to our API testing, secure code review, and CI/CD hardening practices when issues touch upstream.

Web App Pentest FAQ

Most engagements run 2–3 weeks: 1 week of mapping and automated coverage, 1–2 weeks of manual exploitation, plus a week of reporting. Large multi-tenant SaaS platforms or apps with extensive admin consoles can run 4–6 weeks.

Yes. Our reports are accepted by QSAs for PCI DSS 11.4 (penetration testing of public-facing web applications) and by SOC 2 auditors for CC7.1 controls. We also align to HIPAA 164.308(a)(8), ISO 27001 A.14.2.8, and other frameworks.

No, but source-assisted testing (grey-box) is faster and finds deeper bugs. We can do pure black-box for unauthenticated external testing, or source-assisted for an authenticated multi-role assessment of the same app.

We strongly prefer a staging environment that mirrors production. When production is the only option, we coordinate testing windows, exclude destructive payloads, and avoid sustained-load activities — but real exploitation of business-logic flaws is necessarily harder to make 100% safe.

Typical engagements range from $18,000–$45,000 depending on application size, number of roles, authentication complexity, and whether we test the supporting APIs. Get a fixed quote after a free 20-minute scoping call.
