Scoping & Target Specification

We engage with you to set the scope of the penetration test. Once the scope is locked in, you specify the target URLs, technology stack, scan frequency and optionally add authentication details to kick off vulnerability scanning.

Select the targeted attacks (in-depth webapp scanning, port scanning, sudomain enum, etc) from the list and click on Launch Attack.

Application Vulnerability Scanning

The vulnerability scanning process can be triggered immediately with the “Scan Now” button or scheduled for non-business hours. We use a multiple tool approach - both open source and commercial - to cover maximum attack surface area and minimise false positives. The results are delivered in real-time as each tool is completed. Optionally, you can configure, pick and choose the tools you want to run against the target.

CREST-Certified Manual Penetration Testing

Our expert penetration testing team hold 30+ years of penetration testing experience and hold industry-recognised certifications, covering CREST CRT, CPSA, CISSP, OSCP, OSCE and CEH.

We identify and exploit application-related vulnerabilities from a hacker's perspective using Black and Gray box testing. By intercepting and manipulating parameters, hidden fields, HTTP requests, and API endpoints, we review all application functionality to uncover weaknesses in the design and implementation of security controls. Each entry and exit point of the application is thoroughly analysed to detect legacy and inherent platform vulnerabilities. Our methodology follows leading industry security standards  OWASP and OSSTMM.

Reporting & Agentic AI Vulnerability Validation

We provide three tailored, actionable reports designed for developers, management, and customer stakeholders—each including clear remediation guidance and developer-ready code fixes to accelerate resolution.

Our industry-first Agentic AI vulnerability validation engine verifies findings and retests vulnerabilities  in real time once remediation is deployed, ensuring fixes are effective and reducing repeat security gaps.

Frequently Asked Questions (FAQs)

What is the difference between Web Application Penetration Testing and Vulnerability Scanning?
Plus Icon

A vulnerability scanning or assessment is fully automated, triggering multiple security tools against the target. The results are fully dependent on the tool output and can contain false positives. The penetration test is executed by our certified security consultants in a controlled environment. This simulates real-world attacks to exploit vulnerabilities, offering in-depth testing of all features, including the validation and elimination of false positives.

What types of vulnerabilities are typically tested in web application penetration testing?
Plus Icon

Common vulnerabilities tested include injections, scripting attacks, business logic vulnerabilities, authentication and access control checks, IDOR, error handling, security misconfigurations and many more as defined by the standards such as OWASP Top 10 and OWASP ASVS.

Our team identifies and exploits each application-related vulnerability from a hacker’s perspective. We review application functionality by interception and manipulation of parameters, hidden fields, HTTP requests and API calls to identify and exploit weaknesses in both the design and implementation of security controls. Entry and exit points of the application are closely analysed to discover legacy software and inherent platform vulnerabilities.

How long does a web application penetration test typically take?
Plus Icon

The duration varies depending on the application's size and complexity, with a standard test typically ranging from one day to two weeks. Larger or highly complex applications may require additional time.

What access will you need to perform the testing?
Plus Icon

Testing can be conducted with black-box, grey-box, or white-box approaches. Depending on the chosen mode, access requirements may include application credentials, API keys, or detailed architectural documentation.

Can I get started with just vulnerability scanning and purchase penetration test when I need it?
Plus Icon

Absolutely. The platform allows you to run vulnerability scans before and after the penetration test is completed. Pen Testing is more than a one-off activity.

Is API Penetration Testing included in the Web Application Penetration Test?
Plus Icon

Yes, API pen testingis included in the web application penetration testing as applicationfunctionalities are commonly served over API endpoints. Regular API penetration testing is essential tosafeguard sensitive data and maintain compliance with industry standards.

What are the Benefits of Web Application Penetration Testing?
Plus Icon

Web application penetration testing provides numerous benefits, including the identification of vulnerabilities before they can be exploited by attackers. It enhances application security by offering a detailed analysis of potential risks, helping organizations prioritize remediation efforts. Additionally, this testing fosters compliance with industry standards and regulations, ensuring that web applications remain secure against evolving threats. By regularly conducting web application penetration testing, companies can safeguard their assets and maintain customer trust.
