Web Application and Services

Uncover and eliminate critical vulnerabilities in your web applications before attackers do.

Web applications and APIs are key attack vectors for adversaries, providing access to sensitive data and core systems. SilentGrid’s Web Application and Services Penetration Testing identifies vulnerabilities that evade automated scans by simulating real-world attack scenarios.

Our hands-on, research-driven approach ensures modern web architectures remain secure against emerging threats.

What Sets Us Apart

Realistic Threat Simulation

We replicate the techniques used by real-world attackers, providing insight into how well your applications withstand targeted attacks. This approach ensures vulnerabilities are identified in the same way they would be exploited.

Tailored for Complex Environments

Each engagement is customised to align with your application’s architecture, frameworks, and business logic. This ensures assessments are both comprehensive and relevant, addressing risks specific to your technology stack.

Advanced Manual Testing

Deep manual testing combined with automation identifies hard-to-spot vulnerabilities that generic testing tools often overlook. We focus on uncovering complex flaws such as business logic errors, chained exploits, and misconfigurations that can’t be detected through automation alone.

Technical Innovation

SilentGrid continuously enhances its testing capabilities through active research and custom tool development. Our team investigates emerging web attack techniques and develops bespoke tools to identify complex vulnerability chains across modern web applications and APIs.

This forward-looking approach ensures we stay ahead of evolving attack vectors, offering clients cutting-edge security insights that extend beyond standard testing methodologies.

Methodology

SilentGrid’s penetration testing methodology reflects the latest adversarial techniques and best practices, ensuring comprehensive application coverage. Our approach aligns with established industry frameworks such as OWASP and ASVS (Application Security Verification Standard), ensuring that assessments address the most critical vulnerabilities and adhere to recognised security standards.

  1. Reconnaissance and Threat Modelling

    • Mapping application components and services.
    • Identifying potential attack vectors.
  2. Automated and Manual Testing

    • Running automated scans to detect standard vulnerabilities.
    • Performing manual deep-dive analysis to uncover complex flaws.
  3. Exploitation and Validation

    • Safely exploiting vulnerabilities to demonstrate real-world impacts.
  4. Reporting and Remediation

    • Delivering technical reports with clear remediation paths and development-friendly recommendations.

Deliverables

Our reporting is crafted to drive immediate remediation while providing long-term value for executives and technical teams alike.

You will receive:

  • Comprehensive Vulnerability Report – Detailed technical insights into risks.
  • Proof of Concept (PoC) – Demonstrations showcasing vulnerability exploitation.
  • Remediation Roadmap – Prioritised, actionable fixes.
  • Executive Summary – High-level overview tailored for leadership.
  • Post-Engagement Consultation – Guidance to assist development teams during remediation.

Code-Assisted Penetration Testing

SilentGrid takes penetration testing further with optional code-assisted assessments, combining traditional black-box testing with insights gained from source code analysis. This hybrid approach enhances vulnerability detection by uncovering issues that would be difficult or impossible to identify through black-box methods alone.

Why Code-Assisted Testing?

  • Deeper Analysis: Access to source code allows our experts to identify vulnerabilities in that are often invisible to standard black-box testing techniques.
  • Improved Coverage: Code-assisted testing ensures thorough evaluation of security-sensitive areas.
  • Customised Insights: We provide recommendations tailored to your application’s unique architecture and codebase, helping you strengthen security from the ground up.

Continuous Security Partnership

SilentGrid offers ongoing penetration testing programs designed to evolve alongside your applications.

Through regular testing cycles (e.g., every 6 or 12 months), we:

  • Retest Prior Vulnerabilities – Confirm fixes and identify regressions.
  • Integrate New Techniques – Apply the latest attack methods and tools.
  • Adapt to Changes – Expand scope to test new features and updates.
  • Provide Proactive Mitigation – Refine our approach to stay ahead of shifting threats.

This iterative process aligns security with your development pipeline, preventing vulnerabilities from reaching production.
