// Scope
What We Cover in Your Web Application
Authentication & Session Security
Authorization & Access Control
We test role based permissions, privilege boundaries, object level access, IDOR, and other weaknesses that could allow unauthorized access.
Input Validation & Injection
We evaluate application inputs for vulnerabilities such as SQL injection, XSS, command injection, path traversal, and other injection based attacks.
Business Logic & Workflow Security
We test critical workflows and business processes for logic flaws, transaction manipulation, abuse cases, and unintended application behavior.
API & Endpoint Security
We assess exposed endpoints, API authentication, authorization, data exposure, parameter manipulation, and interactions between the application and its APIs.
Data Protection & Cryptography
We evaluate how sensitive information is stored, processed, transmitted, and protected through encryption and cryptographic mechanisms.
// Methodology
Our Manual First Web Application Testing Methodology
- 01
Application Discovery & Mapping
We map application functions, workflows, inputs, authentication paths, integrations, and sensitive data flows before testing.
- 02
Automated Baseline Testing
We use targeted automated testing to establish a baseline and efficiently identify common application vulnerabilities.
- 03
Manual Security Testing
Certified testers manually assess authentication, sessions, authorization, input validation, business logic, and application specific attack paths.
- 04
Exploitation & Impact Analysis
Confirmed vulnerabilities are safely validated to determine what data, functions, or systems an attacker could realistically access.
- 05
Reporting & Retesting
We document reproducible findings with business impact and remediation guidance, followed by retesting when fixes are implemented.

// What we deliver
Actionable Web Security Insights
A web application penetration test is only as useful as the report it hands back. Every engagement ends with a document built for your developers and your leadership alike, and one that holds up when an auditor starts asking questions.
- Executive Summary
A plain language overview for leadership, covering overall risk and business impact.
- Technical Findings
Detailed results, each with proof of exploitation, affected components, and severity.
- Risk Ranking
Every vulnerability ranked by real world exploitability, not just a raw CVSS score.
- Remediation Guidance
Specific, actionable fixes mapped to your actual stack, not boilerplate.
Why Choose Web Application Testing?
Protect Applications Against Real World Attacks
Pluto Security conducts in depth web application security testing focused on identifying and validating weaknesses that automated tools may overlook. We assess authentication, authorization, session security, input validation, business logic, APIs, data protection, and application specific attack scenarios. By combining manual testing with contextual analysis, we help organizations understand exploitability, potential impact, and the most important steps for remediation.
Manual Application Testing
Our testers manually assess authentication, authorisation, business logic, sessions, inputs, APIs, and sensitive functionality.
Business Logic Assessment
Specialists investigate application workflows for weaknesses attackers could exploit to manipulate intended business processes.
OWASP Aligned Testing
Testing incorporates recognised application security practices to identify common and complex web application vulnerabilities.
Actionable Security Reporting
Detailed findings provide evidence, impact context, and remediation guidance for strengthening application security controls.
How We Run a Web Application Penetration Test
- We test your app as both an outsider and an authenticated user abusing real access.
- We map roles, workflows, and high value functions before we touch a single input.
- We chain small, low-severity gaps into the real attack paths a scan would never connect.
- We validate every finding by hand and capture proof of concept for each exploitable issue.
- We rank results by real world exploitability, then walk your developers through the fixes.

Why Web Application Testing Matters for Your Business
Web application penetration testing helps identify vulnerabilities in your web applications before attackers can exploit them. By assessing authentication, authorization, business logic, and other security weaknesses, our web application security testing helps reduce risk, protect sensitive data, and strengthen your overall application security.
Identify Application Vulnerabilities
Discover weaknesses attackers could exploit through public facing or authenticated application functionality.
Protect Customer Information
Reduce application weaknesses that could expose sensitive customer or organizational data.
Test Authentication Controls
Identify weaknesses allowing attackers to bypass or abuse application authentication mechanisms.
Validate Authorisation
Determine whether users can improperly access functionality or information beyond their permissions.
Detect Business Logic Flaws
Uncover application behaviours attackers could manipulate for unauthorised financial or operational outcomes.
Reduce Web Attack Risk
Address vulnerabilities that could enable compromise, data theft, or application disruption.
Support Compliance Objectives
Provide security testing evidence supporting applicable regulatory and industry requirements.
Improve Application Resilience
Strengthen applications against evolving attack techniques through validated security improvements.
