Find Your Security Weaknesses Before Attackers Do
Professional penetration testing services for London businesses. CREST-approved methodology, comprehensive reporting, and actionable remediation guidance.
Why Penetration Testing Matters
Vulnerability scanners find known issues. Penetration testing reveals how attackers could chain vulnerabilities together to breach your systems. It's the difference between a checklist and a real-world attack simulation.
Prove Your Security
Demonstrate to clients, investors, and regulators that your security isn't just theoretical.
Find Hidden Risks
Discover vulnerabilities that automated scanners miss—business logic flaws, misconfigurations, and attack chains.
Meet Compliance
Required for Cyber Essentials Plus, ISO 27001, PCI DSS, and client security assessments.
Comprehensive Security Testing Services
We test every layer of your technology stack to identify vulnerabilities before attackers exploit them.

Our Testing Methodology
We follow CREST and OWASP guidelines to ensure thorough, professional testing that mimics real-world attack scenarios.
1. Planning & Reconnaissance
Define scope, gather intelligence, map attack surface
- Scope definition and rules of engagement
- Asset discovery and enumeration
- OSINT gathering
- Technology fingerprinting
Choose Your Testing Approach
Black Box Testing
We test with zero knowledge of your systems, simulating an external attacker.
White Box Testing
Full access to source code, architecture docs, and credentials for comprehensive analysis.
Grey Box Testing
Partial knowledge—typically user-level access to simulate a compromised account.
