Different tools for different problems. CoreView governs your M365 tenant operations. GraphWarden secures your Graph API data layer. Together, they provide complete governance.
CoreView and GraphWarden solve fundamentally different problems. CoreView is an M365 administration platform - it manages licenses, automates user lifecycle, enforces governance policies, and provides compliance reporting. GraphWarden is a Graph API security proxy - it filters API responses, manages secrets, and enforces data minimization at the API level.
There is no overlap. CoreView controls what administrators and policies do. GraphWarden controls what applications can see. They complement each other naturally.
CoreView is the leading M365 management platform, trusted by organizations managing over 25 million licenses. It provides a unified console for everything related to M365 tenant administration.
License management - Optimize spending, reclaim unused licenses, and track allocation across the tenant.
User lifecycle automation - Onboarding, offboarding, role changes, and group management with automated workflows.
Governance policies - Enforce configuration standards, detect drift, and maintain compliance across Teams, SharePoint, and Exchange.
Compliance reporting - Pre-built and custom reports for auditors, security teams, and management.
Delegated administration - Give helpdesk and regional admins scoped access without granting full Global Admin.
GraphWarden is a security proxy that sits between applications and Microsoft Graph API. It controls what data flows through the API - per application, per endpoint, per property.
Response filtering - Strip properties, scope by AAD group, and block unauthorized methods on every Graph API call.
Data transforms - 9 transform types (mask, hash, redact, initials, etc.) applied before data reaches the consuming application.
Zero-knowledge secrets - Applications never see real Graph credentials. Secrets live in Azure Key Vault, accessed only by the proxy.
Per-call audit trail - Every API request logged with caller identity, endpoint, matched rule, objects returned vs. filtered.
YAML policy language - Infrastructure-as-code for Graph API governance. Version-controlled, human-readable, auditable.
Different domains, different strengths. Here is how they break down across five key dimensions.
M365 administration and operations. License optimization, user lifecycle, governance policies, compliance reporting.
Graph API data security. Response filtering, property-level access control, data transforms, credential isolation.
Licenses, users, groups, Teams settings, SharePoint configurations, Exchange policies. The administrative layer of M365.
Which properties and objects each application can access through Graph API. The data layer of M365.
Admin console with workflows, automation rules, and reporting dashboards. Operators define policies and actions through the UI.
Transparent HTTP proxy with YAML-based rules. Applications point to GraphWarden instead of graph.microsoft.com. No code changes required.
Governance policies, configuration drift detection, and compliance reporting. Ensures the tenant stays within defined operational boundaries.
Per-call audit trail and data minimization enforcement. Proves exactly what data each application accessed and what was filtered out.
Not applicable. CoreView manages tenant configuration, not application credentials.
Zero-knowledge credential architecture via Azure Key Vault. Applications authenticate with proxy credentials. Real Graph secrets are never exposed.
CoreView governs the tenant. GraphWarden secures the API. Combined, they cover the full M365 governance stack.

No overlap in scope
API Data Security
CoreView ensures your M365 tenant is configured correctly, licenses are optimized, and admin operations follow governance policies. GraphWarden ensures that every application accessing data through Graph API only sees what it is authorized to see - with sensitive properties filtered, transformed, or blocked before they reach the application.
Both products support hybrid deployment. CoreView partners can deploy GraphWarden on existing on-premise or hybrid infrastructure alongside CoreView - giving organizations a complete M365 governance stack that respects data sovereignty requirements.
GraphWarden is available through the CoreView partner ecosystem. If you already work with a CoreView partner, they can add GraphWarden to your M365 governance stack - giving you both tenant administration and API data security through a single relationship.
This partnership reflects the natural fit between the two products: CoreView partners who manage M365 tenants for their customers can now also offer Graph API security as part of a complete governance solution.
Complete your M365 governance stack. CoreView for tenant operations, GraphWarden for API data security. Available through the CoreView partner channel.
