Web Application
Penetration Testing

Manual-led, in-depth security testing of web applications, REST APIs, and GraphQL endpoints — finding the vulnerabilities your scanner cannot.

OWASP Top 10 API Security Authentication Testing Business Logic IDOR SSRF Injection
Overview

Levantis Cyber conducts advanced web penetration testing designed to emulate real-world adversaries targeting modern application stacks. Our approach goes significantly beyond automated scanning — combining deep manual testing, business logic analysis, and adversary-driven techniques to uncover vulnerabilities that matter.

We test against the OWASP Top 10 as a baseline, but our engagements consistently go further — identifying multi-step attack chains, privilege escalation paths, and subtle logic flaws that require genuine attacker thinking to discover. Every application is different, and we treat it that way.

Our operators use the same tools and mindset as real attackers. We don't tick boxes — we find impact.

Testing Methodology
01

Reconnaissance & Surface Mapping

Passive and active enumeration of all application endpoints, parameters, authentication mechanisms, and third-party integrations. We build a comprehensive attack surface map — including undocumented routes discovered through directory brute-forcing, JS analysis, and API schema inspection — before any active testing begins.

02

Authentication & Session Testing

Analysis of login mechanisms, MFA implementations, password reset flows, session token entropy, fixation, and cookie security attributes. We test for account enumeration, lockout bypass, credential stuffing resilience, and OAuth/OIDC implementation weaknesses across all authentication surfaces.

03

Authorisation & Access Control

Horizontal and vertical privilege escalation testing across all application roles. We probe for IDOR vulnerabilities, mass assignment flaws, and insecure direct object references throughout every functional area — including administrative interfaces and multi-tenant boundaries where applicable.

04

Injection & Input Validation

Testing for SQL, NoSQL, LDAP, XPath, OS command, and template injection vulnerabilities across all user-controlled inputs. SSRF, XXE, and file upload abuse are tested thoroughly, along with client-side injection vectors including XSS, DOM clobbering, and prototype pollution.

05

Business Logic Analysis

Manual review of application workflows to identify flaws unique to your application — price manipulation, workflow bypass, race conditions, multi-step process abuse, and feature interactions that create unintended attack paths. These are the vulnerabilities automated tools will never find.

06

API & Integration Security

REST and GraphQL endpoint enumeration, mass assignment, excessive data exposure, and authentication token analysis. We test all documented and undocumented API routes discovered during mapping, including mobile backend APIs, webhook endpoints, and third-party integration surfaces.

07

Reporting & Remediation Support

A detailed technical report with every finding risk-rated using CVSS, full reproduction steps, and proof-of-concept evidence. An executive summary suitable for board consumption. Developer-ready remediation guidance. A debrief call with your team, and a retest of critical and high findings once remediated — included as standard.

What Makes Levantis Different

We focus on impact, not noise. Our operators are experienced application security professionals who approach each engagement as an attacker — not as an auditor working through a checklist. We communicate clearly throughout the engagement and will raise critical findings immediately rather than waiting for the final report.

Every report is written by the operator who conducted the testing — not reformatted by a delivery team. You get direct access to the person who found the issues, and we stay available post-delivery to answer questions and support your remediation effort.

// Vulnerability Classes
