Network Penetration Testing Services in Hong Kong

Cyber threats are evolving faster than ever. If vulnerabilities exist within your systems, attackers will find them—unless you identify and address them first.

At EIRE Systems in Hong Kong, we deliver specialized penetration testing services, providing organizations with the critical insights they need to stay ahead of cyber risks. Our certified cybersecurity professionals simulate real-world attacks to uncover vulnerabilities, evaluate your risk exposure, and offer clear, actionable recommendations to protect your network, applications, and internal systems.

Since establishing EIRE Systems in Hong Kong in 2004, we’ve supported regional and multinational corporations (MNCs) in diverse industries, including finance, healthcare, technology, legal, and manufacturing. Whether your organization is working to meet Hong Kong’s regulatory requirements—such as the Hong Kong Monetary Authority (HKMA), the Securities and Futures Commission (SFC), and the Personal Data (Privacy) Ordinance (PDPO)—or proactively enhance your cybersecurity posture, EIRE Systems is your trusted local partner.

Hong Kong businesses require precise identification of cyber vulnerabilities to maintain operational integrity. EIRE Systems performs penetration testing that replicates real-world attack scenarios, exposing weaknesses within your IT infrastructure. This service enables you to address these vulnerabilities directly, reinforcing your security posture and supporting continuous business operations.

External Network Penetration Testing

Public-facing systems represent critical entry points for cyber threats. EIRE Systems conducts external network security testing to assess these systems, including websites, cloud services, and VPNs, for potential vulnerabilities. This testing identifies specific weaknesses, enabling you to strengthen your perimeter defenses and reduce the risk of unauthorized access. We assess for:

• Open ports and unsecured services
• Firewall configuration errors
• Authentication issues
• Unpatched software flaws
• DNS configuration errors

Through realistic attack simulations, we help you address these findings directly and reinforce your security posture.

Internal Network Penetration Testing

Internal vulnerabilities present significant risks to business operations. EIRE Systems conducts internal network testing to evaluate potential attack pathways within your systems. This assessment identifies weaknesses that could be exploited by unauthorized users or advanced malware. We analyze:

• Access control and privilege escalation risks
• Directory service and identity management gaps
• Endpoint security weaknesses
• Network segmentation errors
• Data exposure and encryption flaws

This in-depth internal review reveals critical issues that traditional security tools may miss.

Wireless Network Penetration Testing

Wireless networks are essential for business operations in Hong Kong, particularly for businesses maintaining remote offices, retail locations, or customer-accessible Wi-Fi. EIRE Systems provides wireless network security assessments to identify vulnerabilities within your Wi-Fi infrastructure. Our wireless testing includes:

• Wi-Fi encryption strength (WPA2/WPA3 evaluation)
• Unauthorized access points and device detection
• Authentication protocol integrity
• Potential man-in-the-middle attack vectors

Addressing these findings strengthens your wireless network security, reducing unauthorized access and data compromise risks.

We follow a structured, proven methodology to assess, test, and report vulnerabilities. Our approach ensures comprehensive security coverage and practical remediation guidance.

Comprehensive Vulnerability Assessment for a Secure Foundation

We begin by thoroughly assessing your IT environment—from network infrastructure to cloud services and endpoints. Using a combination of automated scans and manual verification, we create a detailed picture of your current security landscape, laying the foundation for effective testing.

Focused Security Analysis Tailored to Your Business

Following the assessment, we design and execute targeted penetration tests aligned with your business model, risk profile, and regulatory requirements from the Hong Kong Monetary Authority, the Securities and Futures Commission, and the Personal Data (Privacy) Ordinance. Our Hong Kong-based experts cover:

• External and internal network testing
• Web application and API testing
• Optional social engineering and phishing simulations

Controlled Exploitation to Simulate Real Cyber Threats

To assess the real-world resilience of your defenses, our experts safely exploit identified vulnerabilities in a controlled environment, simulating tactics used by advanced threat actors. This reveals the true impact of potential breaches, from data exfiltration to system compromise.

Actionable Reporting with Practical Remediation Strategies

Mitigate risks and ensure compliance with our actionable security reporting and remediation. Our final report provides a comprehensive vulnerability analysis, offering in-depth descriptions of potential threats. We deliver data-driven risk prioritization, focusing remediation efforts on the highest-impact vulnerabilities, and provide practical, implementable remediation strategies for swift resolution. Our recommendations adhere to Hong Kong regulatory frameworks, strengthening your compliance posture. We bridge the gap between technical details and strategic decisions with accessible insights for all levels

Ongoing Security Monitoring and Expert Advisory

Cybersecurity isn’t a one-time effort—it’s an ongoing commitment. At EIRE Systems, we provide continuous vulnerability management and real-time security monitoring to help Hong Kong businesses maintain a resilient security posture. Our dedicated experts work closely with your team to offer practical advice and proactive guidance, ensuring you stay ahead of emerging threats and compliance demands.
