What it does

Singapore's framework for protecting critical information infrastructure (CII). CII owners must meet codes of practice, run audits and risk assessments, and report prescribed cybersecurity incidents to the Commissioner of Cybersecurity. Providers of licensable services (penetration testing and managed SOC) need a licence. The 2024 amendments extend oversight to foundational digital infrastructure providers, entities of special cybersecurity interest, systems of temporary cybersecurity concern, and CII located overseas, and add civil penalties.

Who it applies to
Owners of designated CII, licensed cybersecurity service providers, and since 2025 foundational digital infrastructure providers (such as cloud and data centre operators), entities of special cybersecurity interest and owners of systems of temporary cybersecurity concern.
Penalties
For some offences, fines up to the greater of SGD 200,000 or 10% of the person's annual turnover in Singapore, plus up to SGD 5,000 a day for continuing offences. The Commissioner may seek a court-ordered civil penalty instead of prosecution (section 37A).
