Most Microsoft 365 environments generate more security signals than any team can manually review. Conditional Access logs, sign-in risk events, Defender alerts, device compliance changes, and SharePoint audit trails all exist — but they live in separate consoles, with no unified view of what happened across which user, on which device, at what time. The platform covered in this service solves this by acting as the centralization layer: collecting signals from across your environment, correlating them into incidents, and surfacing only the detections that actually warrant investigation.
IT Partner delivers this as a structured implementation engagement — not a feature toggle. The difference between a SIEM deployment that works and one that sits idle is the quality of connector configuration, analytics rule selection, and alert tuning done in the first six weeks. That is what this service covers.
What Is Microsoft Sentinel?
Microsoft Sentinel is a cloud-native SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) platform hosted in Azure. It ingests log data from Microsoft 365, Entra ID, the Defender product family, and Azure workloads, then applies analytics rules and machine learning to identify threats that individual product alerts miss. For Canadian organizations, the workspace can be provisioned in the Canada Central or Canada East Azure regions, keeping log data within national borders to satisfy privacy legislation (the Personal Information Protection and Electronic Documents Act, PIPEDA, and the forthcoming Bill C-27).
For the full implementation sequence — including where this platform fits relative to identity and endpoint controls — see the Microsoft 365 Zero Trust Roadmap.
What's Included in the Deployment Service
Every engagement is scoped to your environment. The standard delivery includes:
- Workspace setup and data retention — Log Analytics workspace provisioned in a Canadian Azure region, with retention policies aligned to your regulatory and operational requirements
- Microsoft 365 and Entra ID connectors — Office 365 audit logs, Entra ID sign-in and audit logs, Entra ID Protection risk detections
- Defender connector suite — Defender for Endpoint, Defender for Identity, Defender for Office 365, Defender for Cloud Apps — incident and alert forwarding configured
- Analytics rules and detection content — built-in rule templates enabled and tuned; Fusion ML-based detection enabled and validated for multi-stage attack correlation
- Workbooks and dashboards — operational monitoring views for identity, endpoints, and data access activity
- Automation playbooks (Logic Apps) — initial response automation for high-priority scenarios: account lockout, impossible-travel sign-in, MFA fatigue patterns
- Alert tuning — 4-to-6-week cycle — false positive reduction on high-severity rules; target: below 5% false positive rate on critical detections before handoff
- Operational handoff package — response playbook templates for the top five alert types your environment generates; connector and rule inventory for ongoing administration
For environments with on-premises Active Directory, MDI sensor deployment and the on-premises AD connector are included as a standard scope item. Complex multi-forest or non-Microsoft log-source integrations are scoped separately.
Managed SIEM vs. In-House: Is It Right for Your Team?
The decision comes down to one question: does your team have the capacity to monitor, triage, and respond to security alerts as an ongoing operational responsibility?
For organizations with a dedicated security operations function — even a small one — IT Partner delivers the platform as an internal capability your team owns. The implementation and tuning are handled by our engineers; your team takes over day-to-day monitoring at handoff.
For organizations without an internal SOC function, the managed SIEM Canada model extends the engagement: IT Partner monitors alerts, triages incidents on your behalf, and provides regular reporting. Both paths are available; scope and pricing differ accordingly.
SIEM Pricing in Canada: E5 vs. Add-On
Microsoft Sentinel is not included in Microsoft 365 E5. This is the most common licensing misunderstanding IT Partner encounters during scoping calls. E5 includes Microsoft Defender XDR — a related but distinct product. The SIEM platform is an Azure consumption service billed independently through your Azure subscription, based on daily data ingestion volume measured in GB per day.
E5 vs. Standalone Add-On
- Microsoft 365 E5 organizations — the platform is added as an Azure service. E5 provides fully licensed Defender XDR data sources, which means high-value signals are already available at no additional connector cost, and effective SIEM spend is lower.
- Microsoft 365 E3 organizations — the platform can be deployed, but connector scope is narrower. IT Partner will assess which data sources are available under your current tier and identify the most cost-effective path before scoping begins.
Cost Planning
For a standard connector scope covering Microsoft 365, Entra ID, and the Defender suite, typical monthly platform costs run between CAD 1,200 and CAD 1,800 per 1,000 seats, including the underlying Log Analytics workspace. Actual spend depends on daily ingestion volume, which varies significantly by connector selection and log verbosity settings. IT Partner provides a fixed-scope implementation quote after a free 30-minute scoping call where ingestion volume is estimated against your connector plan.
Budget planning should begin before the deployment engagement starts — not during it. If you are building a broader Zero Trust implementation plan, the 12-Month Zero Trust Roadmap covers the licensing decision timeline in detail.
How IT Partner Deploys the Platform Step by Step
- Scoping call (Week 0) — Review current licensing, identify available data sources, estimate ingestion volume, confirm workspace region (Canada Central or Canada East for data residency compliance)
- Workspace provisioning (Week 1) — Azure Log Analytics workspace created, retention configured, the SIEM platform enabled, role-based access controls (RBAC) assigned
- Connector configuration (Weeks 1–2) — Microsoft 365 and Defender connectors activated; for hybrid environments, identity sensor deployment on all Domain Controllers and the on-premises AD connector configured
- Detection content and analytics rules (Weeks 2–3) — built-in rule templates reviewed and activated; Fusion detection enabled and validated; custom rules built for environment-specific scenarios identified in scoping
- Workbooks and automation (Weeks 3–4) — operational dashboards configured; Logic Apps playbooks built for top-priority automation scenarios; incident workflow validated
- Alert tuning cycle (Weeks 4–6) — active monitoring of the alert queue; false positive reduction; rule thresholds adjusted to operational targets
- Handoff and documentation (Week 6) — response playbook templates delivered; connector and rule inventory documented; operational briefing for your internal team
For environments with on-premises AD, complex multi-forest configurations, or custom threat detection requirements, the timeline may extend by two to three weeks — identified and scoped in Week 0.
Sentinel vs. Defender XDR: Which Does Your Organization Need?
They serve different functions and are not mutually exclusive.
Microsoft Defender XDR is the unified incident investigation interface across the Defender product family. It correlates alerts from endpoint, identity, email, and cloud app signals into a single queue, with Automatic Attack Disruption for active threat containment. Defender XDR is available at E3 level (partial) and E5 (full capability) — no separate Azure billing required.
The SIEM layer adds capabilities that Defender XDR does not provide on its own: long-term log retention, ML-based Fusion correlation for multi-stage attack scenarios, ingestion from non-Microsoft sources, custom analytics rules, and SOAR automation through Logic Apps. For most Canadian organizations with a security operations function, the recommended architecture is Defender XDR as the primary investigation interface with the SIEM platform as the centralized detection and retention layer behind it.
For organizations earlier in their security maturity journey, a Zero Trust Assessment will identify whether the SIEM investment is the right next step or whether XDR configuration should come first.
Most Canadian organizations that have Microsoft 365 already have some security controls in place. The problem is rarely total absence — it is inconsistent enforcement. A Zero Trust Assessment gives you an objective answer to one question: how effectively are your security controls actually enforced, not just enabled? This service is designed for Canadian businesses that want a structured review of their Microsoft 365 security posture before committing to broader changes.
IT Partner is a certified Microsoft Solutions Partner for Security — which means every Defender workload in this engagement is delivered by engineers with verified Microsoft expertise. Most Canadian organizations on Microsoft 365 E5 are carrying the cost of five security workloads while actively running one or two. Defender for Identity has never been connected to Active Directory. Defender for Cloud Apps holds no governed SaaS integrations. The unified incident queue in the Defender XDR portal sits empty — not because the environment is safe, but because no workload has been put into a production-ready state.
When an attack does land, the reconstruction is manual: the initial phishing lure in one dashboard, the account takeover it triggered in a second, the lateral movement your team missed in a third. Engaging a Microsoft Defender XDR consultant means that reconstruction never has to happen — each workload delivers clean signal, the correlation engine connects them automatically, and your team sees one incident instead of three queues of unrelated alerts. XDR setup in Canada runs 10–20 business days depending on the number of workloads in scope and the complexity of the existing environment.
Microsoft 365 does not protect sensitive data by default — SIN numbers, financial records, and client contracts move through email, SharePoint, and Teams with no inspection, no policy check, and no audit trail. IT Partner configures dlp microsoft purview policies that enforce data protection at the point of sharing, align controls with PIPEDA and Bill C-27, and work around legitimate business workflows rather than blocking them.

Stop guessing. Start saving with smarter Microsoft licensing. In 2026, Microsoft licensing has evolved into a complex ecosystem: NCE commitments, Intune‑based security, and migrations from traditional Volume Licensing. A single wrong choice can lock your business into thousands of dollars in unnecessary spend.
As your Microsoft IT Partner, we go beyond selling licenses — we architect your cloud to ensure every subscription delivers real value.
Zero Trust is not a product you deploy or a project you finish. It is a continuous improvement program built across six architectural pillars: identity, devices, applications, data, infrastructure, and network. This 12-month roadmap provides a practical, phase-by-phase sequence for Microsoft 365 environments in Canada: what to do each quarter, what licensing is required, and what "done" looks like before you move to the next phase.
