External Infrastructure

Your external infrastructure forms the frontline of your organisation’s security perimeter, protecting critical assets from unauthorised access. While penetration testing focuses on identifying vulnerabilities within targeted external systems, true perimeter resilience requires a broader, continuous approach.

SilentGrid’s External Infrastructure Penetration Testing simulates real-world attack scenarios to assess the security of internet-facing systems, identifying misconfigurations, unpatched services, and potential entry points for adversaries.

For organisations seeking a more comprehensive evaluation of their attack surface, our Perimeter Assessment extends beyond traditional penetration testing, uncovering and cataloguing all internet-exposed assets across your environment.

What Sets Us Apart

Real-World Attack Simulation

We assess your external infrastructure the way real attackers would – identifying exploitable misconfigurations, outdated services, and exposed entry points. This ensures vulnerabilities are detected and validated under conditions that mirror actual threats.

Focused Penetration Testing or Holistic Perimeter Analysis

While external penetration testing targets specific systems or environments, our Perimeter Assessment delivers a holistic analysis of your entire internet-facing footprint. This service identifies forgotten or misconfigured assets that could inadvertently expose your organisation to risk.

By pairing External Infrastructure Testing with a Perimeter Assessment, you gain full visibility into your external attack surface – not just critical systems, but development environments, staging servers, and shadow IT resources.

Advanced Manual Testing

We combine deep manual testing with automated scans to uncover hidden vulnerabilities that traditional tools often miss. This ensures that chained exploits, overlooked misconfigurations, and complex security flaws are identified and remediated.

Technical Innovation

SilentGrid leverages custom tooling and continuous research to stay ahead of emerging attack vectors targeting external environments. Our focus on innovation ensures clients benefit from cutting-edge assessments that evolve alongside adversary techniques.

Methodology

SilentGrid’s external penetration testing adheres to established frameworks such as OWASP, CIS Benchmarks, and NIST 800-53, ensuring assessments align with industry best practices and security standards.

1. Reconnaissance and Asset Mapping

   • Enumerating exposed systems, DNS records, and cloud resources.
   • Identifying misconfigurations, open ports, and forgotten systems.

2. Vulnerability Discovery and Exploitation

   • Running automated scans and manual tests to uncover exploitable vulnerabilities.
   • Validating and safely exploiting findings to demonstrate impact.

3. Privilege Escalation and Lateral Movement

   • Assessing pathways from compromised external systems to internal environments.
   • Identifying risks associated with exposed credentials, misconfigurations, and open services.

4. Reporting and Remediation

   • Providing comprehensive, actionable reports designed to prioritise high-risk issues and outline remediation steps.

Deliverables

SilentGrid’s reporting provides actionable intelligence for technical teams while offering high-level insights for executive leadership.

You will receive:

• Comprehensive Vulnerability Report – A detailed overview of all identified vulnerabilities, including severity and impact.
• Proof of Concept (PoC) – Demonstrations validating critical vulnerabilities.
• Remediation Roadmap – Clear and prioritised recommendations for remediation.
• Executive Summary – A concise overview highlighting risks and the business impact of findings.
• Consultation and Retesting – Post-engagement guidance and retesting to validate the effectiveness of remediation efforts.

Continuous Security Partnership

For organisations seeking ongoing protection, SilentGrid offers continuous external infrastructure assessments.

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

• Retest Prior Vulnerabilities – Validate remediation efforts and identify regressions.
• Assess New Systems – Ensure newly deployed infrastructure is free from vulnerabilities.
• Integrate Emerging Techniques – Apply the latest attack methods to stay ahead of evolving threats.

For broader, long-term security, our Perimeter Assessment provides an adaptive approach to defending against external threats by uncovering unknown or misconfigured systems before attackers do.
