Common Questions
Frequently Asked Questions
How mature is Hong Kong’s cybersecurity readiness?
The Enterprise Cyber Security Readiness Index scored 52.8/100 in 2024 — classified as Basic maturity. While up 5.8 points from the prior year, this signals significant gaps in policy, technology, processes, and human awareness. Organizations should treat this as an urgent call to invest in professional cybersecurity partnerships.
What will the new critical-infrastructure law require?
While final details are still emerging, the law is expected to mandate security assessments, incident reporting to authorities, and compliance audits for designated critical infrastructure operators. Organizations in sectors like finance, energy, transport, and telecommunications should begin preparing now by engaging a cybersecurity partner with regulatory expertise.
How much do cybersecurity services cost in Hong Kong?
Managed SOC services typically range from HK$40,000–HK$120,000/month for mid-size organisations. Virtual CISO engagements cost HK$25,000–HK$80,000/month. One-time penetration tests range from HK$80,000–HK$400,000. Compare these against the average ASEAN breach cost of $4.34 million — professional cybersecurity is always a fraction of the risk.
Should I choose a global firm or a local boutique?
Global firms offer scale and 24/7 SOC coverage. Local boutiques like Atlant Security provide personalized, vendor-neutral advice with direct access to senior practitioners. Many organizations benefit from a hybrid approach: a boutique for strategic advisory and assessment, combined with a global MSSP for continuous monitoring.
Why is phishing such a critical threat in Hong Kong?
Phishing surged 108% in the most recent year, with HKCERT recording 7,811 cases and over 48,000 malicious URLs. Hong Kong’s position as an international financial hub makes it a prime target for credential harvesting, business email compromise, and CEO fraud. Any cybersecurity partner you select must demonstrate strong email security, user awareness training, and incident response capabilities for phishing-based attacks.
How does PDPO compare to GDPR?
Hong Kong’s Personal Data (Privacy) Ordinance (PDPO, Cap 486) predates GDPR and shares many principles — purpose limitation, data security, individual rights. However, it differs in enforcement mechanisms and does not have GDPR’s percentage-of-turnover fines. With proposed amendments and increasing enforcement activity, organizations should treat PDPO compliance as seriously as GDPR, especially if they handle cross-border data.
