MECS & Open MECS
Entitlement and Reporting is table stakes for the market data business. The Multi-source Entitlement Control Service (MECS) permissions all data sources and data types whether publishing or subscribing.
The Universal Entitlement Layer for Market Data
A single entitlement layer for all your market data—fully standardized, fully auditable, and fully under your control. Entitlement and Reporting is table stakes for the market data business. The Multi-source Entitlement Control Service (MECS) permissions all data sources and data types whether publishing or subscribing.
What is MECS
One Entitlement Layer for a Fragmented World:
Market data entitlement is one of the most complex and overlooked challenges in financial institutions. Each data provider operates with its own entitlement model, reporting logic, and control mechanisms—creating fragmentation, risk, and inefficiency.
MECS solves this by introducing a centralized entitlement control layer that spans all vendors, data types, and applications.
It ensures that every piece of data—whether streaming, historical, or contributed—is accessed only by the right user, in the right context, at the right time.
The Problem - Why Entitlement is Broken Today
- Each data provider has different entitlement systems and interfaces
- No central place to check or enforce permissions across vendors
- Limited visibility into who is using what data
- Inconsistent and insufficient reporting
- High operational burden and compliance risk
- This fragmented approach leads to higher costs, audit exposure, and vendor lock-in—ultimately slowing down innovation.
The Solution - Standardize, Control, and Enforce
MECS acts as a universal entitlement engine that:
- Permissions all data sources and data types, whether publishing or subscribing
- Provides a centralized lookup service for user-level access control
- Enforces entitlements across all connected applications
- Standardizes entitlement logic across vendors
- Enables consistent reporting and audit readiness
- With MECS, entitlement becomes a built-in capability—not a manual process.
Key Capabilities
Multi-Vendor Entitlement Control
Manage permissions across all data providers through a single interface.
On-Behalf Permissioning
Applications can check user entitlements dynamically—ensuring proper access at runtime.
Centralized Reporting
Provider-approved reports with full transparency into data usage and access.
End-to-End Visibility
Track who accessed what data, when, and how—across the entire organization.
OpenMECS Extension
Extend entitlement control to downstream or external systems not directly connected to the platform.
From Compliance Burden to Strategic Control
Cost OptimizationCost Optimization
Avoid paying for unused or misallocated data.
Audit & Compliance Confidence
Automated reporting and full audit trails reduce regulatory risk.
Operational Efficiency
Eliminate manual entitlement management and reconciliation.
Vendor Independence
Standardize entitlement across providers → easier switching and negotiation.
Scalability
Built for cloud and real-time environments with dynamic control.
The Control Layer of the ONE Platform
MECS is a core component of the ONE Platform, ensuring that all data flowing through the platform is fully entitled and controlled
It enables:
- Secure data distribution
- Consistent governance across all applications
- Integration with other components such as MuSICA, CalcNode, and FICONEX
- Without MECS, true vendor neutrality and data control are not possible.
