Web Application Security

Web Application
Penetration Testing

Manual, in-depth security testing of web applications and APIs. We go beyond automated scanners to find the vulnerabilities that matter β€” business logic flaws, chained exploits, and authentication bypasses that put your users and data at risk.

What we test

Our testers go far beyond running Burp Suite against a scope list. We invest time understanding your application's business context to find vulnerabilities that automated tools miss entirely.

Injection (SQLi, NoSQLi, SSTI, LDAP)
XSS (Reflected, Stored, DOM)
Broken Access Control / IDOR
Authentication Bypass
Session Management Flaws
JWT / OAuth Misconfigurations
Server-Side Request Forgery
XXE Injection
File Upload Vulnerabilities
Business Logic Flaws
Race Conditions
Mass Assignment
Security Misconfigurations
Insecure Deserialization
GraphQL / REST API Security
MANUAL TESTING FIRST
Every finding is manually confirmed and exploited. We don't forward scanner output as a report β€” we demonstrate real, business-contextualized impact with working proof-of-concept exploits.
🎯

Business Logic Testing

We spend time learning how your application is supposed to work, then look for ways to abuse it β€” price manipulation, privilege escalation, multi-step workflow bypasses.

πŸ”—

Vulnerability Chaining

Individual low-severity issues often chain into critical impact. We demonstrate realistic attack scenarios that show true business risk.

🌐

API & Microservices

REST, GraphQL, WebSocket, and gRPC endpoints are fully tested, including hidden endpoints discovered during recon.

Choose your testing approach

BLACK BOX

Zero Knowledge

Our testers receive no prior information about the application. We simulate a real external attacker with no inside knowledge β€” starting from open-source reconnaissance.

Ideal for: External threat simulation, compliance requirements
GRAY BOX

Partial Knowledge

Testers receive credentials, API documentation, or basic architecture context. This maximises coverage efficiency and models insider or post-breach scenarios.

Ideal for: Most web app assessments β€” best depth vs. time ratio
WHITE BOX

Full Knowledge

Full access to source code, architecture diagrams, and internal docs. The most thorough approach β€” catches vulnerabilities invisible from the outside.

Ideal for: Pre-launch audits, high-assurance applications, financial platforms

How we test

01

Scoping & Kick-off

Define targets, testing windows, out-of-scope areas, and communication channels. We set up a secure shared workspace for findings and updates.

Rules of EngagementIP Whitelisting
02

Reconnaissance & Mapping

Enumerate endpoints, parameters, technologies, and authentication mechanisms. We map the full attack surface before touching anything.

CrawlingJS AnalysisAPI Discovery
03

Vulnerability Identification

Assisted scanning plus deep manual analysis of all attack surface areas. We focus human effort where automation is blind.

Burp Suite ProManual Testing
04

Exploitation & PoC Development

Each vulnerability is exploited to demonstrate real-world impact. We write clean, reproducible proof-of-concept code.

Reporting & Debrief

Executive summary + full technical report with CVSS scores, PoC screenshots, and step-by-step remediation guidance. Live debrief call included.

06

Verification Re-Test

After your team remediates, we re-test all findings at no additional cost and issue a remediation verification letter.
