Microsoft 365 deployment and configuration

We run enterprise Microsoft 365 deployments from license provisioning through go-live. Our architects handle every layer of the deployment — not just installation.

• Tenant configuration and baseline security hardening.
• Microsoft 365 Apps for Enterprise deployment via Intune or Configuration Manager.
• Exchange Online setup, hybrid configurations, and DNS cutover.
• Teams deployment, governance framework, and call quality optimization.
• SharePoint Online and OneDrive configuration, permissions structure, and information architecture.
• Microsoft Entra ID (formerly Azure AD), Conditional Access, and MFA rollout.

Cloud migration services

We migrate from on-premises Exchange, SharePoint, Google Workspace, and legacy file shares to Microsoft 365. Migration scope drives timeline.

• Exchange to Exchange Online migration (cutover, staged, hybrid).
• SharePoint on-premises to SharePoint Online with content restructuring.
• Google Workspace to Microsoft 365 migration (email, Drive, Calendar, Contacts).
• File share to OneDrive and SharePoint migration with metadata mapping.
• Microsoft 365 tenant-to-tenant migration for M&A and divestitures.

Governance and compliance

Governance prevents sprawl. Compliance keeps regulated data under control. We build both into the foundation — not as afterthoughts.

• Microsoft Purview sensitivity labels and auto-labeling policies.
• Data Loss Prevention (DLP) for email, SharePoint, Teams, and Copilot.
• Retention policies and records management aligned with your regulatory schedule.
• eDiscovery, legal hold, and content search configuration.
• Teams governance: creation policies, naming conventions, lifecycle management, guest access controls.
• Information Barriers for regulated industries where communication restrictions apply.

Security and threat protection

Microsoft 365 security requires active configuration — it is not on by default. We harden every tenant we deploy.

• Microsoft Defender for Office 365 Plan 2: Safe Attachments, Safe Links, anti-phishing.
• Microsoft Defender for Endpoint: device onboarding, Attack Surface Reduction rules.
• Entra ID Conditional Access with Zero Trust policy design.
• Privileged Identity Management (PIM) for just-in-time admin access.
• Microsoft Sentinel integration for cross-platform security monitoring.
• Insider Risk Management and Communication Compliance for regulated industries.
