Web App Security Testing

01 · Why it matters

The web app threat landscape.

Web apps are the most common entry point for attackers. The data is brutal - and the consequences worse.

43% of breaches start at the web layer.

Intelligence gathering and attack surface mapping consistently identify the web tier as the first foothold. Every misconfigured route is a candidate entry point.

Top threats persist, even with awareness.

SQL injection, cross-site scripting, and CSRF still account for the majority of critical findings - because they live in business logic, not in dependency manifests.

Security equals trust.

Customers and regulators demand defensible apps. A clean attestation is the difference between renewing the contract and losing it - and between brand equity and a public incident.

02 · How it works

Five steps, scope to sign-off.

Comprehensive web application security testing following industry standards and best practices.

01

OWASP Top 10 testing

Systematic testing against the most critical web application security risks identified by OWASP.

Day 1–2 · AI + senior-led

02

Business-logic flaw discovery

Deep analysis of application workflows to identify logic flaws that automated tools miss.

Day 2–4 · Humans only

03

API & integration security

Comprehensive testing of APIs, third-party integrations, and data exchange mechanisms.

Day 3–5 · Authenticated

04

Auth & session review

Thorough evaluation of authentication mechanisms, session management, and access controls.

Day 4–6 · Senior-led

05

Exploit sim & reporting

Real-world attack simulation with developer-ready reporting and remediation guidance.

Day 6–7 · Plus 90d retests

03 · Coverage

The checklist, in full.

Comprehensive coverage of web application security vulnerabilities and attack vectors - every category, every engagement.

01·INJECTION↗

Injection attacks

SQLi, NoSQLi, and template injection across every input boundary - query strings, headers, file uploads, JSON bodies.

SQLi · NoSQLi Template injection OWASP A03

02·AUTH↗

Auth flaws

Weak session management, broken multi-factor flows, password reset abuse, and credential-stuffing exposure.

Broken MFA Session mgmt OWASP A07

03·INPUT↗

Input validation

Cross-site scripting, CSRF, command injection - every place untrusted data crosses a trust boundary.

XSS CSRF Command injection

04·API↗

API & integrations

Token management, data exposure, BOLA, BFLA, and shadow endpoints across REST and GraphQL surfaces.

Token mgmt Data exposure API Top 10

05·BIZ-LOGIC↗

Business logic

Privilege escalation, workflow bypass, and ordering attacks that automated scanners cannot reach.

Priv escalation Bypass attempts Humans only

06·REPORT↗

Report & attestation

Developer-ready tickets, executive summary, and a compliance attestation letter - mapped to OWASP and SOC 2.

Dev-ready Attestation 90d retests
