Buyer Decision Checklist

Cybersecurity buying in Singapore turns on PDPA, the CSA Cybersecurity Act, and sector mandates from MAS and MOH. Use this checklist before you shortlist.

How to evaluate a cybersecurity vendor in Singapore

  • Confirm scope, rules of engagement, and who owns remediation before you sign.
  • Treat ISO 27001 / SOC 2 Type II / CREST as a baseline — ask for the auditor name and audit date, not just a logo.
  • Separate 'managed' from 'monitored': ask exactly what the vendor does at 3am when an alert fires, and whose name is on the on-call roster.
  • Check which reports are board-, audit-, or regulator-ready (MAS TRM, HCSF, or IM8 as applicable to you).
  • Get a fixed-fee scope for the first 90 days with unit pricing for extra endpoints, log volume, or incident-response hours.

Verify for Block65

  • Confirm key details directly with the vendor — this listing isn't vendor-managed yet.
  • Ask for two recent Singapore client references you can speak with.
  • Ask for a written scope of services before comparing quotes.
  • Request evidence of relevant certifications and their current validity.

Questions to ask

  • What is included in scope and retest, and what is explicitly excluded?
  • Can you share two Singapore clients in my sector and size that I can speak to?
  • How do you meet PDPC's 72-hour breach-notification window contractually?
