Inline Enforcement
Not just detection. Not just alerting. GraphWarden sits in the data path and actively controls what data flows through the API. Unauthorized data is filtered before it reaches the application - not flagged after the fact.
How GraphWarden Compares
GraphWarden occupies a unique position: the only purpose-built security proxy for Microsoft Graph API. Here is how we compare to adjacent solutions.
Most solutions in this space address parts of the problem. API gateways handle routing but lack Graph-specific filtering. Data governance platforms classify data at rest but do not control data in transit. SSPM tools audit posture but do not enforce inline. Admin platforms manage tenant operations but not API data access. Developer tooling helps teams validate permissions before shipping, but stops at the developer's machine. GraphWarden is the only solution that provides inline Graph API response filtering with per-property, per-object granularity and zero-knowledge credential management — continuously, across production tenants.
Detailed Comparisons
Read our in-depth analysis of how GraphWarden compares to each solution.
API Gateway
Azure API Management
General-purpose API gateway. Lacks Graph-specific filtering, object scoping, and zero-knowledge secrets. Designed for API publishing, not data security enforcement.
Read full comparison → Data GovernanceMicrosoft Purview
Governs data at rest. Complementary to GraphWarden which governs data in transit through Graph API. Different layers of the same security stack.
Read full comparison → SSPMAdaptive Shield
Audits SaaS security posture across 150+ apps. Detects misconfigurations and compliance issues but does not enforce inline API filtering.
Read full comparison → Data SecurityVaronis
Broad data security platform. Monitors and alerts on data access across files, SharePoint, and AD but does not filter API responses inline.
Read full comparison → M365 ManagementCoreView
M365 admin platform and GraphWarden distribution partner. Complementary, not competitive. CoreView manages operations; GraphWarden secures API data.
Read full comparison → Developer ToolingMicrosoft Dev Proxy
Open-source CLI from Microsoft that intercepts Graph API calls during development to detect excessive permissions and simulate errors. Operates shift-left on developer machines. Complementary to GraphWarden, which enforces at runtime across production tenants.

What Makes GraphWarden Different
Three capabilities that no other solution in this space provides.
Per-Object and Per-Property Granularity
Rules are evaluated against each individual object in the API response. If an app requests /users, only users matching the rule conditions appear. Within each object, only allowed properties are returned. Surgical precision at both the object and property level.
Zero-Knowledge Credential Architecture
Applications never see real Graph credentials. They authenticate with proxy credentials that GraphWarden controls and can revoke instantly. Real secrets live in Azure Key Vault, accessed only through Managed Identity. No credentials stored on disk, in code, or in config files.
