WEB APPLICATION PENETRATION TESTING
Test Your Web Application From an Attacker's Perspective
G-2 provides controlled web application penetration testing for web systems, SaaS platforms, e-commerce, portals, APIs, and integrations. We investigate security weaknesses, validate realistic exploitation paths, document findings, and can support remediation through the G-2 development team.
Vulnerability Scanning
VS
Penetration Testing
Vulnerability scan can flag a potential weakness.
A penetration test adds human investigation and controlled attempts to determine whether and how a weakness could actually be exploited.
The goal is to understand what is vulnerable, why it matters, and what should be fixed first.
Preparing for a security review
a customer, auditor, internal security programme, or applicable compliance scope requires testing evidence.
Launching a new product or major release
significant functionality, APIs, or integrations are going live.
Handling sensitive data
the system processes customer, payment, financial, or business-sensitive information.
Responding to a security concern
you need to validate a suspected weakness and understand its impac
Meeting a customer or partner requirement
security testing is required before signing or onboarding
Application & Business Logic Testing
Assess application behaviour, workflows, input handling, and relevant security controls.
Authentication & Access Control Testing
Assess authentication, sessions, permissions, roles, and privilege boundaries.
API & Integration Testing
Test agreed APIs, endpoints, and integration points within scope.
Vulnerability & Exploitation Testing
Investigate weaknesses and validate realistic exploitation within scope.
Security Remediation
Support development fixes and review them where included in scope.
What We Test
Customer portals
Corporate web systems
SaaS platforms
E-commerce
Admin panels
CRM/ERP systems
APIs
Integrations
Internal web applications
From Scoping to Remediation
-
1 — Scope
define targets, objectives, access, and boundaries.
-
2 — Test
investigate the application and validate realistic attack paths.
-
3 — Find & Fix
document findings and remediate identified weaknesses.
-
4 — Review / Retest
verify relevant fixes where this is included in the agreed scope.
What You Get
Prioritised security findings
Technical evidence and proof of concept
CVSS-based severity scoring, where used
Business impact explained clearly
Recommended remediation steps
Development support and fix verification where included in scope
Why G-2
Security Testing Backed by Software Engineering
A penetration test tells you where a system is vulnerable. The next challenge is fixing it.
G-2 combines security testing with in-house software development, so identified weaknesses can move directly from finding to remediation within the same organisation.
Test. Find. Fix.
What Does Web Application Penetration Testing Cost?
Cost depends on system size and complexity, number of targets, testing approach, access provided, and required depth of testing.
What is web application penetration testing?
A controlled security assessment in which specialists investigate a web-based system from an attacker's perspective and validate security weaknesses.
What is the difference between a vulnerability scan and penetration testing?
Scanning primarily identifies potential weaknesses automatically. Penetration testing adds human investigation and controlled exploitation to validate what can actually be abused.
What methodology do you follow?
The methodology depends on the scope and objective. OWASP guidance can be used where appropriate; exact frameworks and scoring methods are agreed during scoping.
What systems can you test?
Web applications, SaaS, e-commerce, customer portals, admin panels, CRM/ERP systems, APIs, integrations, and internal web systems.
Do I need penetration testing for SOC 2 or ISO 27001?
It may form part of security evidence required by a customer, auditor, or applicable compliance programme. Requirements depend on the framework and scope.
Can G-2 fix vulnerabilities found during testing?
Yes. G-2's development team can work on remediation.
Can penetration testing affect my system?
Testing is authorised and scoped in advance; operational risk depends on the system and techniques used.
How long does a test take?
The timeline depends on scope, targets, access, approach, and assessment depth.
How much does it cost?
The quote depends on the same scope factors. Tell us what needs to be tested and we will define the assessment scope.
