As organizations accelerate their digital transformation journeys with SAP S/4HANA, the question of how to architect
Governance, Risk, and Compliance (GRC) becomes critical. Should you go with the Embedded GRC model or stick with the Hub (Standalone) model?
Here’s a strategic breakdown to help IT Directors and SAP GRC leaders make informed decisions.
What Are the Models?
- Model
- Embedded
- Hub
- Description
GRC is installed as an add-on within the S/4HANA system itself
GRC runs on a separate server and connects to ECC or S/4HANA via RFCs
Benefits of the Embedded Model
- Lower TCO: No separate infrastructure, reducing hardware, licensing, and maintenance costs
- Real-Time Integration: Access data and risk analysis are native to the ERP system no replication needed
- Unified UX: Users access GRC features directly within S/4HANA, streamlining workflows
- Future-Proofing: SAP’s roadmap favors embedded GRC as part of its S/4HANA strategy
Considerations Before You Embed
- Downtime Dependency: GRC availability is tied to the ERP system’s uptime
- Performance Load: If multiple systems feed into one embedded GRC, it may impact ERP performance
- Audit Strategy: Historical data from standalone systems may need archiving or export for compliance
When Is Hub Still Relevant?
- Multi-System Landscapes: If you manage multiple SAP systems (ECC + S/4HANA), a hub model may offer centralized control
- Phased Migrations: For companies still transitioning from ECC, hub GRC allows continuity
- Heavy Customization: Some legacy GRC setups may be easier to maintain in a standalone environment
Flexibility and Foresight
Workflow Customization: Approvals and workflows are highly configurable, with support for complex, multi-level templates beyond the default (standard) settings.
Extending On-Premise Controls: Existing GRC AC customers can extend to support cloud applications seamlessly. For cloud-first organizations, IAG Standard offers a purely cloud-centric approach.
Rulesets & Risk Levels: IAG aligns closely with GRC AC in classifying risks (Critical, High, Medium, Low) and types (SoD, Critical action, Critical permission) enabling familiar, granular controls.
Migration Notes
SAP recommends a Lift-and-Shift approach for moving from Hub to Embedded GRC:
- Manual configuration replication
- SLT (SAP Landscape Transformation) for real-time data migration
- Keep legacy GRC alive for audit purposes
Common Misconceptions About SAP GRC Models
- “Embedded GRC is just a technical deployment choice.”
Reality: It’s a strategic architecture decision. Embedded GRC impacts system performance, upgrade cycles, compliance workflows, and long-term scalability. It’s not just about where the software sits—it’s about how your business manages risk.
- “Hub model is outdated and should be avoided.”
Reality: While SAP is nudging customers toward Embedded GRC for S/4HANA, the Hub model still makes sense for multi-system landscapes, phased migrations, or organizations with heavy customization. It’s not obsolete—it’s situational.
- “Embedded GRC means automatic cost savings.”
Reality: While Embedded GRC reduces infrastructure costs, it may increase complexity in performance tuning, downtime planning, and cross-system access management. Cost savings depend on your landscape and usage patterns.
- “You can migrate GRC configurations 1:1 from Hub to Embedded.”
Reality: Migration is not plug-and-play. It often requires manual reconfiguration, data mapping, and testing. Some legacy setups may not be compatible with Embedded architecture without redesign.
- “Embedded GRC is only for S/4HANA.”
Reality: Technically true, but
misleading. Customers on ECC may still benefit from Hub GRC until they transition. SAP GRC Embedded is designed for S/4HANA, but Hub remains
valid for ECC and hybrid environments.
- “Performance is always better with Embedded GRC.”
Reality: Not necessarily. If multiple systems feed into one Embedded GRC instance, it can strain the ERP system. Hub models can offload processing and isolate risk analysis from core business operations.
Strategic Takeaway
Choosing between Embedded and Hub isn’t just a technical checkbox—it’s a business-aligned decision. The right model
depends on:
- Your system landscape (ECC, S/4HANA, hybrid)
- Compliance needs
- Performance expectations
- Migration timelines
Our Recommendation
If you’re running SAP S/4HANA or planning to migrate soon, Embedded GRC is the strategic choice. It aligns with SAP’s future direction, simplifies architecture, and enhances compliance agility. However, every business is unique. Our team specializes in helping companies assess their GRC landscape and design the right-fit architecture —whether Embedded or Hybrid.
