Web Application & API Pentesting
Whether it’s weak authentication, insecure APIs, or business logic flaws, we emulate real-world attacks to identify security gaps and provide clear recommendations to protect your digital assets.
Our Methodology
Enumeration and Mapping
Enumeration and Mapping
Enumeration and Mapping
Our testing begins with a comprehensive reconnaissance phase, where we gather information about the application or API, such as endpoints, technologies in use, and user flows. This helps us understand how the application operates and identify potential attack surfaces.
Authentication
Enumeration and Mapping
Enumeration and Mapping
Next, we focus on authentication and session management. We test for vulnerabilities like weak passwords, improper session handling, and insecure multi-factor authentication implementations. The goal is to ensure your system enforces robust controls to protect user accounts and sensitive data.
Authorisation
Enumeration and Mapping
Input Validation
Authorisation controls are rigorously tested to verify that users can only access what they’re allowed to. For APIs, this includes verifying role-based access controls (RBAC), scope validation, and token security to prevent unauthorised access to sensitive data or functions.
Input Validation
Input Validation
Input Validation
In the input validation and data handling phase, we simulate attacks such as SQL injection, cross-site scripting (XSS), and API injection to assess how the application or API processes user input. Our testing also evaluates how securely data is transmitted and stored, including encryption and tokenisation methods.
Business Logic
Input Validation
Business Logic
Our assessment delves into business logic flaws, where we identify ways an attacker might exploit application workflows to bypass intended functionality or gain unauthorised access. We also test for vulnerabilities such as rate limiting issues, excessive data exposure, and improper access controls.
Reporting
Input Validation
Business Logic
During the assessment, all findings are shared in real-time through our reporting portal, giving you immediate visibility into potential risks. Once the engagement is complete, a comprehensive PDF report can be downloaded, detailing vulnerabilities, evidence, and practical remediation steps.

A penetration test, also known as a pentest, is a simulated cyber attack on a computer system to identify vulnerabilities and weaknesses. Securebytes provide pentesting services to help businesses strengthen their security.
A penetration test is a snapshot in time assessment, providing a momentary evaluation of the security posture of a system or network. As technology and security landscapes evolve, new vulnerabilities may emerge, making it important to conduct periodic assessments to maintain a robust security stance. For most companies we typically recommend a penetration assessment is conducted annually or after any major changes to applications or systems. However, for some companies that are rapidly deploying new services or changes this could be as often as quarterly.
The duration of the test is based on the scope. The Securebytes® team work with clients to understand their penetration testing requirements and understand their risks to determine the most appropriate scope.
Some common types of cyber threats include malware, ransomware, phishing attacks and Denial-of-Service (DoS) attacks. These threats can cause significant damage to your digital assets and compromise your business operations.
