MAS TRM Guide for Cybersecurity Vendors and Partners (2026)
Singapore's financial institutions buy security to satisfy two layers of MAS rules: short, legally binding Notices and the longer Technology Risk Management (TRM) Guidelines. This guide maps both to the product categories that vendors, distributors and partners actually sell — and flags what is changing.
Key facts
- Who: financial institutions regulated by MAS — banks, insurers, capital markets intermediaries, payment institutions and others.
- Binding layer: MAS Notices on Technology Risk Management and on Cyber Hygiene. Since 10 May 2024 these are issued per institution type under the Financial Services and Markets Act 2022 (FSM-N series). They replaced the older Notices 644 and 655 for banks.
- Hard numbers: report a relevant incident to MAS within 1 hour; root cause and impact report within 14 days; no more than 4 hours of unscheduled downtime per critical system in any 12 months; a recovery time objective (RTO) of no more than 4 hours per critical system.
- Cyber hygiene: six mandatory controls — secure admin accounts, risk-based patching, written security standards, network perimeter defence, malware protection and MFA.
- Guidance layer: the TRM Guidelines (January 2021), 13 substantive sections from governance to IT audit. Not statutory, but MAS assesses institutions against them in supervision.
- What's changing: a June 2026 consultation proposes eight new Notice requirements, including an IT asset inventory that covers cryptographic assets and an immutable or offline backup. These would take effect 12 months after the final Notices are published.
1. The binding layer: TRM Notice and Cyber Hygiene Notice
Notices are legally binding, and a breach can lead to regulatory action. A deal that helps an institution meet a Notice requirement is usually easier to fund than one that maps only to a guideline.
Technology Risk Management Notice
| Requirement | What it says | Typical product categories |
|---|---|---|
| Availability of critical systems | Unscheduled downtime of each critical system must not exceed 4 hours in total within any 12-month period. | High availability and DR, DDoS protection, observability and capacity monitoring |
| Recovery time objective | RTO of no more than 4 hours for each critical system, validated at least once every 12 months. | Backup and recovery, DR orchestration, resilience testing |
| Incident notification | Notify MAS as soon as possible and no later than 1 hour after discovering a relevant incident. | SIEM and detection, SOC/MDR, incident response retainers |
| Root cause analysis | Submit a root cause and impact analysis report within 14 days of discovery. | Forensics and IR services, log retention, case management |
| Customer information | Implement IT controls to protect customer information from unauthorised access or disclosure. | DLP, encryption and key management, database security, access governance |
Cyber Hygiene Notice
| Control | What it says | Typical product categories |
|---|---|---|
| Administrative accounts | Secure every administrative account on operating systems, databases, applications, security appliances and network devices against unauthorised access or use. | Privileged access management (PAM), privileged remote access, session recording |
| Security patches | Apply security patches within a timeframe matched to the risk; where no patch exists, put compensating controls in place. | Vulnerability management, patch management, virtual patching / IPS |
| Security standards | Maintain written security standards for every system and make systems conform, or mitigate the gap. | Configuration and hardening assessment, CSPM, compliance scanning |
| Network perimeter defence | Implement controls at the network perimeter to restrict all unauthorised traffic. | NGFW, WAF, secure web gateway, SASE |
| Malware protection | Implement malware protection on every system where available and feasible. | EPP/EDR, email security, server and container protection |
| Multi-factor authentication | MFA for all admin accounts on critical systems and for all accounts on systems that access customer information over the internet. | MFA and identity providers, PAM, phishing-resistant authenticators |
2. The guidance layer: TRM Guidelines (January 2021)
The Guidelines set out MAS's expectations in detail. Institutions are expected to observe them, and supervisors use them to test how mature an institution's controls are. The table maps each substantive section to the categories it usually pulls into a purchase.
| Section | Focus | Typical product categories |
|---|---|---|
| 3. Technology Risk Governance and Oversight | Board and senior management accountability, roles | GRC platforms, board reporting |
| 4. Technology Risk Management Framework | Risk identification, assessment, register | GRC and IT risk management, asset inventory |
| 5. IT Project Management and Security-by-Design | Security built into projects | Threat modelling, architecture review services |
| 6. Software Application Development and Management | Secure SDLC, testing, open-source use | SAST/DAST, software composition analysis, API security |
| 7. IT Service Management | Change, configuration, incident and problem management | ITSM, configuration management |
| 8. IT Resilience | Availability, recoverability, DR testing | Backup and DR, DDoS protection, resilience testing |
| 9. Access Control | Least privilege, privileged access, remote access, access reviews | IAM and IGA, PAM, MFA, ZTNA |
| 10. Cryptography | Algorithms, key management | KMS/HSM, PKI and certificate lifecycle |
| 11. Data and Infrastructure Security | Data protection, network and endpoint security, virtualisation and cloud | DLP, segmentation, endpoint, cloud security |
| 12. Cyber Security Operations | Threat intelligence, monitoring, incident response | SIEM, SOC/MDR, threat intelligence, SOAR |
| 13. Cyber Security Assessment | Vulnerability assessment, penetration testing, adversarial simulation | VA/PT services, red teaming, breach and attack simulation |
| 14. Online Financial Services | Securing customer-facing channels, customer authentication, fraud | Fraud detection, customer MFA, bot management, WAF |
| 15. IT Audit | Independent audit of technology risk controls | Audit logging, evidence collection, compliance reporting |
3. What is changing in 2026–2027
Proposed amendments to the TRM Notices (consultation June 2026)
On 10 June 2026 MAS consulted on amendments to its TRM Notices; the consultation closed on 31 July 2026. The proposals add eight areas. Revised Notices would take effect 12 months after the final versions are published.
| Proposed area | What it adds | Where demand may move |
|---|---|---|
| IT asset management | A complete, current inventory of IT assets, including cryptographic assets and open-source and third-party components | Asset discovery / CAASM, SBOM and SCA, cryptographic inventory |
| IT risk assessment and monitoring | Regular assessments covering supply-chain and AI-related risks, a risk register and key risk indicators | GRC, third-party risk, AI governance |
| Capacity planning | Enough capacity for critical systems, including traffic surges | Observability, capacity management |
| Change management | Prevent unauthorised changes; test changes to critical systems before production | ITSM, configuration drift and change control |
| Continuous monitoring | Continuous system and security monitoring of critical systems, with defined alert thresholds | SIEM, observability, MDR |
| Immutable or offline backup | Backup of data crucial to relevant business services that cannot be altered or is kept offline | Immutable backup, cyber recovery vaults |
| Incident management | A framework with roles, evidence preservation, communications and senior management notification | IR platforms and retainers, forensics |
| Unscheduled downtime | Partial or intermittent disruption explicitly counts toward the 4-hour limit | Resilience, DDoS protection, monitoring |
Third-party risk management guidelines (consultation March 2026)
MAS consulted in March 2026 on Guidelines on Third-Party Risk Management, which would supersede the Guidelines on Outsourcing. As of this review, MAS's third-party risk management page still lists the proposals as a consultation, and the current outsourcing rules (including MAS Notice 658 for banks) remain in force. For vendors, this means more due-diligence questions about security controls, subcontractors and exit plans.
4. Using MAS TRM in a sales conversation
- Anchor on Notices first. "This closes a Cyber Hygiene Notice gap" funds faster than "this aligns with the Guidelines".
- Ask about the last MAS inspection and internal audit findings. Findings come with deadlines and owners, often the Head of Technology Risk and the CISO.
- Bring evidence, not features. Institutions need audit trails, reports and test results they can show supervisors and auditors.
- Expect vendor due diligence. Outsourcing and third-party risk rules mean questionnaires on your own controls, data location and subcontractors. Prepare these before the shortlist.
- Watch the amendment timeline. Once the final Notices are published, the 12-month clock starts. Asset inventory, cryptographic inventory and immutable backup are new budget lines.
