fixed critical vulnerabilities within 10 days of receiving our penetration test report, thanks to our clear guidance and expert support.

Why Choose a Penetration Testing Provider?

Partnering with a penetration testing provider is essential for identifying vulnerabilities before cyber attackers can exploit them. Penetration testing evaluates your internal cybersecurity response, supports ISO 27001 compliance, and strengthens your eligibility for cyber insurance. It also builds trust with clients and stakeholders while improving your overall security posture and awareness.

Recent Penetration Testing Reviews

“Cybergen’s report finally bridged board and engineering. Clear attack narrative, PoCs, and CVSS priorities turned a messy backlog into a two-week plan. Auditors accepted the ISO/NIST mapping immediately. Best testing value we’ve bought.” — CTO, SaaS

“We expected a PDF; we got an action plan. Each finding had evidence, business impact, and owners. Our team closed top risks in days and used the compliance mapping to satisfy insurers.” — Head of IT, manufacturing

“Thorough without slowing us down. The executive summary won budget, and developer-ready steps made fixes painless. We reduced phishing exposure and third-party risk within a month, with measurable progress for the board.” — COO, healthcare group

Frequently Asked Questions about Penetration Testing

  • What is penetration testing?

    Penetration testing (or ethical hacking) is a simulated cyberattack against your systems to identify and safely exploit vulnerabilities. It helps you understand real-world risks and how attackers could gain unauthorised access.

  • Why do I need a penetration test?

    Penetration testing reveals security gaps that automated tools may miss. It provides a realistic assessment of your defences and helps prioritise remediation based on actual exploitability.

  • What types of penetration tests do you offer?

    Cybergen offers external, internal, web application, wireless, and social engineering tests. We tailor each engagement to your infrastructure, goals, and compliance needs.

  • How often should I conduct a penetration test?

    We recommend at least annually or after significant changes as new applications, infrastructure upgrades, or regulatory requirements to ensure continuous security assurance.

  • What will I receive after the test?

    You’ll receive a detailed report outlining vulnerabilities, their severity, exploitation methods, and clear remediation guidance. We also provide a debrief session to walk you through our findings.

  • Is penetration testing safe for my systems?

    Yes. All tests are conducted in a controlled, authorised manner by experienced professionals. We follow strict methodologies to avoid disruption to your live environment.

  • What’s the difference between vulnerability scanning and penetration testing?

    Vulnerability scanning identifies known issues using automated tools. Penetration testing goes further simulating real attacks to exploit vulnerabilities and assess their actual risk.

  • Can penetration testing help with compliance?

    Yes. Penetration testing supports compliance with standards like ISO 27001, PCI DSS, and GDPR by demonstrating proactive risk management and technical security testing.
