SAP Role Redesign & Security Migration for S/4HANA
Mitigate between 10% and 25% in inflated FUE cloud licence fees, eliminate £M+ audit penalties, and maintain strict compliance with NIS2 and UK governance frameworks with Tango Technologies’ Cortex Suite.
Optimise your Migration with CortexSAP S/4HANA Role Migration: The High-Stakes 2026 Landscape
As enterprises navigate the final stretch toward the 2027 SAP ECC end-of-mainstream-maintenance deadline, an effective SAP S/4HANA role migration has transitioned from a technical roadmap item to a board-level financial and governance priority. Treating security, access controls, and role design as a simple “lift and shift” exercise is one of the most expensive missteps an enterprise can make.
In modern RISE with SAP and S/4HANA Cloud environments, authorisation concepts directly dictate cloud subscription tiering, software licence consumption, and cyber exposure. Carrying forward legacy ECC role debt leads to catastrophic cost inflation and severe regulatory non-compliance.
Simultaneously, regulatory bodies across the UK and EU are enforcing unprecedented compliance mandates. From NIS2 and DORA to localised corporate governance reforms, senior executives are now personally accountable for digital operational resilience and access controls.
At Tango Technologies, we empower CFOs, CISOs, and CIOs to execute a seamless SAP S/4HANA role migration, transforming security from a cost-centre delay into a strategic, ROI-generating asset that protects enterprise value.
The True Cost of Migration Failure
Without automated role redesign and continuous governance, legacy ECC vulnerabilities compound during SAP S/4HANA role migration.
Financial & Commercial Exposure
-
10%–25% Inflated FUE Licence Costs: Unoptimised legacy roles grant overly broad authorisations, automatically categorising basic users as high-cost “Advanced Users” under SAP’s Full User Equivalent (FUE) model.
-
£500k–£3.5M Audit True-Up Penalties: Failure to manage indirect usage and digital access liabilities during SAP S/4HANA role migration frequently triggers massive, unbudgeted software licence true-up bills.
-
£20,000/Day Hypercare Delays: Role-related access blocks during cutover stall business operations, extending costly system integrator burn rates.
GRC & Audit Liabilities
-
80%+ Toxic SoD Inheritance: Over 80% of legacy ECC role concepts contain critical Segregation of Duties (SoD) violations that break financial control frameworks when mapped to S/4HANA.
-
6–9 Month Audit Remediation Cycles: Manual role remediation post-go-live consumes thousands of internal hours, delaying external audit sign-offs and investor reporting.
-
Material Weakness Disclosures: Uncontrolled access permissions lead to formal external audit qualifiers and public compliance failures.
Legislative & Statutory Mandates
-
Up to £17.5M or 4% Global Turnover Fines: Strict compliance frameworks (NIS2, DORA, UK GDPR) mandate strict access control enforcement and breach prevention.
-
Personal Director Liability: Corporate governance updates enforce strict personal accountability for board members regarding internal controls and cyber resilience.
-
Supply Chain Disqualification: Failure to demonstrate Zero Trust access controls limits your ability to bid on high-value public sector and enterprise contracts.
Cybersecurity & Operational Threats
-
£3.4M+ Average Data Breach Cost: Over-privileged user accounts are the primary vector for lateral attacker movement and insider data exfiltration.
-
Unmonitored Privileged Access: Unrestricted “Firefighter” usage during migration cutovers leaves system backdoors open to unrecorded configuration changes.
-
Clean Core Degradation: Custom legacy authorisation objects bypass SAP standard Fiori apps, creating operational instability in cloud environments.
Introducing the Cortex Suite
The modular security, governance, and commercial optimisation engine built specifically for modern SAP S/4HANA role migration and RISE with SAP landscapes.
Analyses granular user activity and authorisations to map precisely to SAP’s FUE (Full User Equivalent) model, preventing subscription overspending and eliminating Digital Access liabilities.
- ✓ FUE classification reduction
- ✓ Indirect usage audit protection
Provides clear visual risk analytics for Segregation of Duties (SoD), enabling compliance officers to pinpoint, simulate, and remediate access conflicts before go-live.
- ✓ Visual SoD conflict mapping
- ✓ Automated access certifications
Automates the migration from legacy ECC transaction codes to S/4HANA Fiori catalogues, building streamlined, least-privilege role concepts aligned with Clean Core principles.
- ✓ Automated Fiori catalogue mapping
- ✓ Least-privilege role builds
Captures migration execution intelligence and leverages AI analytics to predict security bottlenecks, suggest auto-remediations, and keep projects on schedule.
- ✓ Predictive migration analytics
- ✓ AI-driven role remediations
Monitors SAP landscapes in real time to detect active cyber threats, unauthorised system changes, and suspicious user behaviour across cloud and on-premise instances.
- ✓ Real-time threat detection
- ✓ Behavioural anomaly alerts
Powers emergency privileged access (Firefighter), identity lifecycle requests, and rigorous audit trails during migration cutover, hypercare, and routine operations.
- ✓ Integrated Firefighter access
- ✓ Time-bound emergency audit logs
Unifies data across all Cortex modules into single-pane executive dashboards, delivering complete operational visibility for management and external auditors.
- ✓ Unified executive dashboards
- ✓ Cross-module audit reporting
Combining operational precision, commercial licence protection, and continuous GRC compliance into one cohesive ecosystem for S/4HANA.
