Cybersecurity Services for Financial Services
Threat Monitoring & Detection
Global ITN helps financial institutions monitor security events, identify suspicious activity and coordinate investigation and remediation. Monitoring coverage, alert response arrangements and service hours are defined according to the agreed support package and operating requirements.
Incident Response and Recovery
Global ITN supports financial institutions with structured incident handling, including initial assessment, containment coordination, technical investigation, remediation and recovery planning. Response times, responsibilities and recovery arrangements are defined in the agreed service scope.
MAS Notice 655 Cyber Hygiene
The MAS Notice on Cyber Hygiene (Notice 655 and its equivalents) sets baseline security requirements for regulated firms. We help you meet these fundamentals, from securing administrative accounts to timely patching and multi-factor authentication, so the essentials are firmly in place. Where firewall and network-security controls are required, Global ITN also supports FortiGate firewall deployment and security configuration.
Penetration Testing & Vulnerability Management
Global ITN helps financial institutions identify and address security weaknesses through vulnerability assessments, remediation planning and coordinated penetration testing where included in the agreed service scope. Specialist testing may be delivered through qualified security partners, with findings prioritised for remediation.
Identity & Privileged Access Security
Financial institutions depend on privileged access across Microsoft 365, cloud infrastructure, finance platforms, payment systems and business-critical applications. A compromised administrator account can expose sensitive client information, disrupt operations or provide an attacker with access to multiple systems at once.
Global ITN helps financial-services firms strengthen identity controls through multi-factor authentication, role-based access, privileged-account separation, conditional access policies and periodic access reviews. Administrative privileges can be restricted to authorised personnel and aligned with job responsibilities, while dormant, shared or unnecessary accounts can be identified and removed.
For firms operating in regulated environments, identity security is also about maintaining clear accountability. Access changes, administrator activity and privileged permissions should be traceable and capable of being reviewed when required. These controls can form part of a broader MAS TRM-aligned IT support and cybersecurity programme.
For organisations introducing AI-assisted processes, Global ITN can also help define security controls for AI-enabled workflows, including access boundaries, permissions, integrations and operational safeguards.
Endpoint & Microsoft 365 Security
Laptops, desktops, mobile devices and Microsoft 365 accounts are common entry points for phishing, credential theft, malware and unauthorised access. Financial-services teams also handle commercially sensitive documents, customer information and transaction-related communications, making endpoint and cloud-account protection particularly important.
Global ITN supports financial firms with endpoint security, device management, email protection, Microsoft Defender capabilities, MFA, security-policy configuration and monitoring of suspicious account activity. Controls can be applied consistently across corporate devices while helping reduce risks created by unmanaged endpoints, outdated software or weak authentication.
Microsoft 365 security can also include protection around Exchange Online, SharePoint, OneDrive and Teams, depending on the organisation’s environment. The objective is to create a practical security baseline that supports day-to-day operations without making legitimate access unnecessarily difficult for employees.
These capabilities complement broader financial services IT support in Singapore, where cybersecurity, infrastructure management and operational resilience need to work together.
Firewall, Network & Secure Connectivity
Financial institutions require secure and reliable connectivity between offices, cloud platforms, remote employees, third-party providers and business applications. Weak firewall rules, poorly segmented networks or unmanaged remote-access services can increase both cybersecurity exposure and the potential impact of an incident.
Global ITN helps financial-services organisations manage firewalls, VPN connectivity, secure remote access, network segmentation and security-policy configuration. Network controls can be designed to restrict unnecessary traffic, separate sensitive systems and provide clearer visibility into connections between users, infrastructure and external services.
For organisations with multiple locations or hybrid environments, secure connectivity also needs to support availability and operational continuity. Firewall configuration, monitoring and change management should therefore be considered alongside backup, incident response and infrastructure-support processes.
For organisations with more specialised requirements, these controls can be coordinated with managed IT services for banks and fintech firms or IT support for payment firms in Singapore.

Cybersecurity Evidence for MAS and Audit Review
Cybersecurity controls are more useful when an organisation can demonstrate that they are implemented, maintained and reviewed. During internal governance reviews, customer due-diligence exercises or regulatory and audit discussions, financial firms may need evidence showing how technology risks are being managed in practice.
Global ITN can help organisations maintain operational evidence such as access-review records, security-policy settings, endpoint status, firewall configurations, patching records, backup checks, monitoring outputs, incident records and remediation actions. The exact evidence required will depend on the organisation’s systems, risk profile and review scope.
The objective is not to provide regulatory certification, but to help establish a clearer and more auditable technology-control environment. Technical evidence can then support management discussions, internal assurance activities and external reviews.
Organisations reviewing their broader technology-risk controls can also consider MAS TRM compliance IT support and dedicated MAS TRM cybersecurity controls as part of the same improvement programme.
Where cybersecurity findings require broader technical changes across multiple controls, our MAS TRM remediation and implementation support service can help address the identified gaps and document the resulting changes.
Cybersecurity by Financial-Sector Type
Cybersecurity requirements vary across financial organisations because their operating models, systems, users and third-party dependencies are different.
Banks and fintech firms may require stronger protection around digital platforms, cloud environments, APIs, administrator access and high-volume customer-facing services. Security controls need to support rapid technology delivery while maintaining appropriate access, monitoring and resilience.
Payment firms often depend on transaction platforms, external APIs, payment gateways and continuous connectivity. Their cybersecurity approach should consider transaction availability, sensitive data, third-party connections, privileged access and incident response.
Fund managers and family offices may place greater emphasis on protecting investment information, executive communications, financial records, Microsoft 365 accounts and access to specialist portfolio or fund-administration platforms.
Family offices with lean internal teams can also use our secure family office IT support service for ongoing operational security and support.
Insurance firms may need to protect policyholder information, internal business applications, document repositories, endpoints and third-party integrations while maintaining reliable access for operational teams.
Rather than applying an identical security stack to every organisation, Global ITN helps financial-sector firms align cybersecurity controls with their actual technology environment, operational dependencies and risk profile
