Attack
Surface
Exposed
We simulate targeted attacks against your internet-facing infrastructure to uncover exploitable vulnerabilities — before malicious actors find them first.
What We Test
Your Internet-Facing Attack Surface
Every public-facing asset is a potential entry point. We systematically identify and test each one to give you a clear picture of your real-world exposure.
Perimeter Firewalls & VPNs
Testing firewall rulesets, VPN concentrators, and network edge devices for misconfigurations and known vulnerabilities.
Public-Facing Web Servers
Enumerating and testing all externally accessible web services, including staging environments and forgotten test instances.
DNS & Subdomain Discovery
Comprehensive DNS reconnaissance to identify shadow IT, dangling records, and subdomain takeover opportunities.
Email & Mail Servers
Assessing mail server security, SPF/DKIM/DMARC configuration, and resilience against spoofing and relay attacks.
Cloud-Exposed Services
Identifying publicly accessible cloud resources including storage buckets, databases, and serverless endpoints.
Remote Access Services
Testing RDP, SSH, and other remote access gateways for weak authentication, brute-force resilience, and protocol vulnerabilities.
Why It Matters
Benefits of External Testing
Understanding your external exposure is the first step to reducing risk. Here is what you gain.
See What Attackers See
We show you exactly which assets are visible from the internet and which ones are vulnerable, giving you the attacker's perspective before they get it.
Prioritised, Actionable Findings
Every vulnerability is risk-rated with clear remediation steps. No generic scanner output; real findings ranked by business impact.
Reduce Your Attack Surface
We help you identify and remove unnecessary exposures: unused services, forgotten subdomains, overly permissive configurations.
Meet Compliance Requirements
External penetration testing satisfies requirements under Cyber Essentials Plus, ISO 27001, PCI DSS, and GDPR security obligations.
Validate Your Defences
Confirm that your firewalls, WAFs, and monitoring tools actually detect and block real attack techniques, not just textbook scenarios.
Expert-Led, Not Automated
Our consultants manually test beyond what scanners find. We chain vulnerabilities together to demonstrate real-world impact.
Our Process
How It Works
A structured, transparent process from scoping through to remediation support.
Scoping
We define your external perimeter, agree rules of engagement, and set testing windows.
Reconnaissance
OSINT gathering, subdomain enumeration, service discovery, and technology fingerprinting.
Testing
Manual exploitation attempts against identified targets using attacker methodologies.
Reporting
Clear, prioritised report with executive summary, technical detail, and remediation guidance.
