CSA CISOaaS cybersecurity services 2026

The Cyber Security Agency of Singapore (CSA) uses CISO as-a-Service (CISOaaS) to help organisations strengthen cybersecurity through onboarded consultants. For organisations starting their cybersecurity journey, consultants can perform a cyber-health check against CSA’s Cyber Essentials and/or Cyber Trust measures, develop a tailored Cybersecurity Health Plan, help close identified hygiene gaps, and prepare the organisation for at least Cyber Essentials certification. CSA describes this as support for the “people” and “process” pillars; IMDA’s SMEs Go Digital addresses the technology pillar through pre-approved solutions (CSA, updated 31 August 2026).

Services, funding and application route

Eligible small and medium-sized enterprises (SMEs) may receive up to 70% co-funding when they sign up with CSA-onboarded CISOaaS consultants for the Cyber Essentials or Cyber Trust health-plan services. The application route is IMDA’s SMEs Go Digital platform, where eligible organisations identify a consultant and package; organisations without funding eligibility may approach a listed consultant directly. CSA also describes CISOaaS services for vulnerability assessment and penetration testing (VAPT), for which eligible SMEs may receive up to 70% co-funding. The published percentage is a maximum support level, not a guarantee that every applicant or every cost will receive that amount (CSA, CISOaaS service page).

Sector-specific and service boundaries

CSA’s page separately describes CISOaaS support for entities covered by the Health Information Act (HIA) cybersecurity and data-security essentials, and DPOaaS for social service agencies under the National Council of Social Service (NCSS) to address Personal Data Protection Act obligations and MSF Data Security Instructions. Incident-response CISOaaS is intended for organisations that have experienced a cybersecurity incident, but the page states that funding support is currently unavailable for that service. CSA does not endorse a particular provider or guarantee the quality of a provider’s work; the programme is a support and consultancy route, not a cybersecurity certification awarded automatically by CSA (CSA, CISOaaS service page).

Service pathways and sector-specific scope

CSA describes cybersecurity support through three practical pillars: CISOaaS health plans address the people and process pillars, while IMDA's SMEs Go Digital supports the technology pillar through pre-approved solutions. The pathways are related but not interchangeable. An organisation may use CISOaaS to assess its readiness against Cyber Essentials or Cyber Trust measures and then separately procure technology or appoint a certification body; a consultant's health-plan work does not itself award either CSA mark (CSA, page updated 11 September 2026).

The HIA route is for entities required to meet the Health Information Act Cybersecurity and Data Security Essentials. The DPOaaS route is different: it is intended for social service agencies under NCSS to address Personal Data Protection Act data-protection-officer obligations and MSF Data Security Instructions, and can be added to a CISOaaS Cyber Essentials engagement. VAPT is another distinct service: vulnerability assessment identifies and ranks weaknesses, while penetration testing is an authorised attempt to identify exploitable vulnerabilities. These scopes should not be merged into one universal CISOaaS package or applied to every organisation in Singapore (CSA, page updated 11 September 2026).

Incident response, providers and funding limits

CISOaaS incident response is intended for organisations that have already encountered a cybersecurity incident and is a post-incident service that complements the preventive Cyber Essentials pathway. CSA states that funding support is currently unavailable for incident response, even though eligible SMEs may receive up to 70% co-funding for specified health-plan and VAPT services. Organisations that do not qualify for funding may still approach a listed consultant directly, and cybersecurity providers can apply to be onboarded through CSA. “Onboarded” does not mean CSA endorses or guarantees a provider’s work; organisations remain responsible for selecting services and assessing their own risks (CSA, page updated 11 September 2026).
