- Description of customisation
- Users can customise the service by defining which business systems are integrated with Microsoft Teams and SharePoint, how data is surfaced, and how workflows and interactions are presented to users. Customisation is performed through configuration of connectors, embedded interfaces, permissions, and workflow logic within Microsoft 365 by authorised customer administrators and system owners.
Scaling
- Independence of resources
- Our service runs entirely within Microsoft’s cloud infrastructure, which is designed for multi-tenant scalability and high availability. Microsoft 365 and Power Platform services use elastic scaling and load balancing to ensure consistent performance regardless of demand. Each customer’s data and configuration remain isolated within their own tenant, so usage spikes from other organisations do not impact your environment. Microsoft’s global datacentres provide geo-redundancy and automated failover, and service-level agreements (SLAs) guarantee uptime and responsiveness. Continuous monitoring and proactive resource management further ensure that performance remains stable under varying workloads.
Analytics

Availability and resilience
- Guaranteed availability
- The service is delivered as a cloud‑hosted SaaS solution with Microsoft’s guaranteed availability of 99.9% for Microsoft 365 services, including SharePoint Online and Microsoft Teams. Microsoft ensures availability through redundancy, automated failover and proactive maintenance. Planned maintenance is scheduled with advance notice where possible. iThink 365 relies on Microsoft’s platform SLAs and does not provide a separate uptime guarantee.
- Approach to resilience
- The service is built on Microsoft 365 and Azure, which provide enterprise‑grade resilience through redundant architecture, geo‑paired regions and automated failover. Continuous monitoring and proactive maintenance minimise disruption. Tenant isolation ensures other organisations’ usage does not impact performance. Datacentre architecture and failover details are available from Microsoft on request.
- Outage reporting
- The service reports outages through multiple channels to ensure users are informed promptly. Public dashboard: Displays current service status, including any outages or planned maintenance, accessible via the web. Email alerts: Registered users receive notifications for service disruptions, maintenance windows, and incident resolutions. API: Available for integration with organisational monitoring tools, providing real‑time status updates programmatically. Incident reports include start and end times, affected components, and any mitigation steps taken. Users can monitor service health proactively and plan work around any disruptions. Post‑incident summaries are provided to support review, auditing, and compliance requirements.

Only authorised administrators can manage integration configurations, Microsoft 365 security settings, and governance controls across Teams and SharePoint. Privileged operations are logged and monitored through Microsoft 365 audit logs. Support channels require authenticated accounts, and iThink 365 access is granted only when needed for support and removed immediately after engagement. This ensures all management and support interactions remain secure, auditable, and compliant with organisational policies.

These cover access control, data protection, incident management, change management, and monitoring. Reporting structure: Security responsibilities are defined across organisational and technical teams. A designated Security Officer oversees compliance, reporting directly to senior management. All incidents are logged, escalated, and reviewed according to severity, with documented mitigation steps. Policy enforcement: Access is controlled using role-based permissions and multi-factor authentication. Users are required to follow security best practices, while administrative and operational activity is monitored through audit logs. Regular training ensures staff understand and adhere to policies. Security reviews, internal audits, and automated monitoring help maintain compliance. Incident response: Any suspected breaches trigger immediate investigation and reporting, following a formal escalation process. Lessons learned are applied to update policies, configurations, and controls. This structured approach ensures that the service maintains data confidentiality, integrity, and availability, while providing public sector organisations with clear visibility of security governance and adherence to recognised standards.

- Configuration and change management approach
- The service follows formal configuration and change management processes aligned with recognised standards (CSA CCM v4.0, SSAE-18/ISAE 3402). All components, including workflows, APIs, integrations, and infrastructure, are tracked through their lifecycle with version control and documented histories. Proposed changes are assessed for security and operational impact, tested in a controlled environment, and approved by authorised personnel. Audit logs and monitoring tools track all changes, ensuring compliance and transparency. This approach maintains service stability, security, and reliability, allowing updates, enhancements, and patches to be deployed safely while providing public sector organisations with a fully auditable and controlled change process.

Potential threats are assessed through automated scans, internal security reviews, and threat intelligence from Microsoft Security, CERT-UK, and other recognised sources. Risks are prioritised by severity and impact on workflows, data, and integrations. Security patches are tested in a controlled environment and deployed promptly, with critical vulnerabilities addressed as quickly as possible. Continuous monitoring and audit logs ensure emerging threats are identified and remediated, maintaining service security, operational continuity, and compliance for public sector organisations.
- Protective monitoring type
- Complies with a recognised standard, for example CSA CCM v4.0 or SSAE-18 / ISAE 3402
- Protective monitoring approach
- Identifying compromises: Continuous monitoring of workflows, APIs, system logs, and network activity detects anomalies, suspicious behaviour, or potential security breaches. Automated alerts and threat intelligence feeds from Microsoft Security and CERT-UK support rapid identification of risks. Responding to incidents: Once a potential compromise is detected, incidents are escalated according to severity. Investigation and containment measures are initiated immediately, including isolating affected components and applying mitigation steps. Response time: Critical incidents are addressed as quickly as possible, with formal incident reporting and post-incident review. Lessons learned inform updates to security controls and procedures.
- Incident management type
- Complies with a recognised standard, for example, CSA CCM v4.0 or ISO/IEC 27035:2011 or SSAE-18 / ISAE 3402
