Information security — Security is infrastructure, not an afterthought

Overview

Ransomware and phishing grow daily. Without security fundamentals, a single incident can paralyse an SME.

Ransomware, phishing, insider threats. Risk grows every day. GNS builds complete information security for Hong Kong SMEs on the ISO/IEC 27001 standard, covering risk assessment to incident response.

We have designed security for government departments and public bodies, and apply the same standard to SMEs. Security is not a luxury, it is part of the foundation.

Best fit: Suitable for Hong Kong SMEs needing ISO 27001 alignment, insurer-mandated security certification, or post-incident remediation.

FAQ

  • We are an SME, do we really need all this?

    Depends on industry and data sensitivity. We can start with an assessment, identify the key risks, then propose phased improvements to fit your budget.

  • How do we know if we have been breached?

    We use log analysis, endpoint detection and vulnerability scans to spot indicators of compromise. If you suspect a breach, contact us for emergency response.

  • Our staff keep falling for phishing emails. Can you help?

    Yes. We run phishing simulations, send mock phishing emails regularly and train staff who click, building awareness over time.

  • Can SMEs afford ISO 27001 certification?

    Formal ISO 27001 certification is costly, but not every SME needs the formal certificate. We can first help you build a security management system aligned with the ISO 27001 framework, implemented incrementally, and decide later whether to pursue formal certification.
