12 Hours or Else: Hong Kong’s Cybersecurity Explained

Hong Kong has officially enacted a new cybersecurity law aimed at securing critical infrastructure, a move that brings its regulatory framework closer to mainland China’s. The Protection of Critical Infrastructures (Computer Systems) Bill, passed on March 19, 2025, requires key industries—such as banking, energy, healthcare, and telecommunications—to strengthen their cybersecurity defenses, conduct regular risk assessments, and promptly report security incidents.

The law introduces several key requirements:

• Designation of Critical Infrastructure Operators (CIOs): Companies in critical sectors must register as CIOs and comply with cybersecurity directives.
• Mandatory Cybersecurity Measures: Organizations must implement security protocols, including network monitoring, encryption, and multi-layered defenses.
• Incident Reporting Obligations: Cyber incidents must be reported to the Cybersecurity Affairs Office (CAO) within 12 hours of detection.
• Compliance Audits: Annual risk assessments and audits are required, with periodic reports submitted to regulators.
• Penalties for Non-Compliance: Companies failing to comply face fines up to HK$5 million ($640,000) and potential criminal liability for executives in severe cases.

While the law is intended to protect essential services, its implications for businesses and foreign investors are being closely examined. How does this compare to established privacy laws like the European Union’s General Data Protection Regulation (GDPR), Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA), and Brazil’s Lei Geral de Proteção de Dados (LGPD)?

A Cybersecurity Law, Not a Privacy Law

Unlike GDPR, PIPEDA, and LGPD, which focus on protecting personal data and consumer rights, Hong Kong’s new law is centered on securing critical infrastructure from cyber threats. It mandates cybersecurity audits and incident reporting within 12 hours, with penalties reaching HK$5 million ($640,000) for non-compliance.

This places it in line with China’s Cybersecurity Law (2016) rather than the more consumer-focused privacy laws seen in Europe and the Americas. While GDPR, PIPEDA, and LGPD impose data protection requirements on businesses handling personal information, Hong Kong’s law is more concerned with national security and cyber resilience.

Concerns and Implications

One of the key concerns about the law is its potential impact on foreign investment. Some analysts warn that increased compliance costs and strict reporting deadlines may deter businesses from operating in Hong Kong, particularly given recent shifts in its regulatory landscape.

Additionally, while officials have stressed that the law does not target personal or commercial data, critics argue that its broad scope and alignment with China’s cybersecurity policies could create uncertainty for businesses handling sensitive information.

“Companies need clarity on what’s expected of them,” said George Chen, co-chair of digital practice at The Asia Group. “Cybersecurity is crucial, but regulatory stability is just as important for economic growth.”

Final Word

Hong Kong’s cybersecurity law represents a shift toward stronger national security controls over digital infrastructure rather than consumer privacy protections. While it brings the region’s regulatory framework closer to China’s, it differs sharply from GDPR, PIPEDA, and LGPD, which prioritize personal data rights.

For businesses operating in Hong Kong, compliance will now involve both cybersecurity regulations and existing data privacy laws—a complex balancing act in an evolving digital landscape.
