External Infrastructure Penetration Testing
Simulate real world adversary attacks against your public facing infrastructure, cloud environments, and network perimeters to identify exploitable vulnerabilities before threat actors do.
Overview
Your external attack surface is the first line of defence against cyber threats. Every internet facing asset, from web servers and mail gateways to VPN endpoints and cloud services, represents a potential entry point for adversaries. Our external infrastructure penetration testing replicates the tactics, techniques, and procedures used by sophisticated threat actors to systematically identify and exploit weaknesses in your perimeter defences.
We combine automated reconnaissance with deep manual analysis to uncover vulnerabilities that scanners miss, including complex attack chains, misconfigured cloud services, and exposed administrative interfaces. Our assessments are aligned with the MITRE ATT&CK framework to ensure comprehensive coverage of real world adversary behaviours.
Our Assessment Methodology
Attack Surface Discovery
- Enumerate all internet facing assets including subdomains, IP ranges, and cloud resources
- Identify exposed services, open ports, and running software versions
Vulnerability Assessment
- Scan for known CVEs across all discovered services and applications
- Test SSL and TLS configurations for weak ciphers and protocol vulnerabilities
Exploitation and Pivoting
- Attempt exploitation of identified vulnerabilities to validate real world risk
- Test for credential based attacks including brute force and credential stuffing
Impact Analysis and Reporting
- Document the full attack chain from initial access to potential impact
- Quantify business risk for each exploitable vulnerability
Attack Surface Discovery
- Enumerate all internet facing assets including subdomains, IP ranges, and cloud resources
- Identify exposed services, open ports, and running software versions
- Discover shadow IT assets and forgotten infrastructure components
- Map DNS configurations, mail servers, and certificate transparency logs
Vulnerability Assessment
- Scan for known CVEs across all discovered services and applications
- Test SSL and TLS configurations for weak ciphers and protocol vulnerabilities
- Evaluate firewall rules, network segmentation, and access control lists
- Assess cloud service configurations for public exposure and misconfigurations
Exploitation and Pivoting
- Attempt exploitation of identified vulnerabilities to validate real world risk
- Test for credential based attacks including brute force and credential stuffing
- Evaluate VPN and remote access gateway security controls
- Assess the potential for lateral movement from compromised external assets
Impact Analysis and Reporting
- Document the full attack chain from initial access to potential impact
- Quantify business risk for each exploitable vulnerability
- Provide prioritised remediation recommendations with implementation guidance
- Deliver findings mapped to MITRE ATT&CK tactics and techniques
