Offensive Security

Web Application Penetration Testing

Assess web applications and APIs for vulnerabilities in access control, data handling and business logic.

Service Overview

A focused technical assessment with clear outcomes

Web application penetration testing evaluates how an application behaves when its security assumptions are challenged. NetPhantom examines the application and relevant APIs within an agreed scope to identify vulnerabilities that could expose data, bypass authorization or enable unintended application behavior.

Every engagement begins with an agreed scope, written authorization and clear rules for testing. The exact activities depend on the systems, objectives and constraints established with the client before work begins.

Areas of Focus

What we assess

Testing is tailored to the engagement. Relevant areas can include the following.

Authentication and session controlsIncluded where relevant to the agreed scope, environment and engagement objectives.
Authorization and access controlIncluded where relevant to the agreed scope, environment and engagement objectives.
Input handling and server side behaviorIncluded where relevant to the agreed scope, environment and engagement objectives.
Sensitive data exposureIncluded where relevant to the agreed scope, environment and engagement objectives.
Application and API business logicIncluded where relevant to the agreed scope, environment and engagement objectives.
Client side security and security configurationIncluded where relevant to the agreed scope, environment and engagement objectives.
TESTING METHODOLOGY

Web application penetration testing methodology

Application testing examines the way users, roles, data and application functions interact, with controlled validation of weaknesses that could create practical risk.

01
Application scope

Confirm applications, environments, test accounts, user roles, exclusions and rules of engagement.

02
Application mapping

Map functionality, endpoints, workflows, data flows and trust boundaries relevant to the assessment.

03
Control testing

Evaluate authentication, authorization, session handling, input processing and other relevant security controls.

04
Abuse case testing

Test business logic and realistic misuse scenarios that automated scanning may not identify.

05
Controlled validation

Validate findings and practical impact without creating unnecessary disruption or exposure.

06
Reporting and retest

Provide evidence, severity context and remediation guidance, then validate selected fixes when appropriate.

Reporting and Deliverables

Clear findings your team can act on

Reporting is designed for both technical teams and business decision makers. Findings are supported by context and organized so remediation can be prioritized.

Executive and technical report
Validated application findings
Evidence and reproduction context
Business impact and severity
Remediation guidance
Retesting options after fixes
Remediation and Validation

From finding to corrective action

NetPhantom does not treat delivery of the report as the end of the conversation. Findings are explained, questions are addressed and remediation priorities are clarified. Where appropriate, retesting can be used to confirm that corrective actions have addressed the validated issue.
