S/4HANA Migration: Security Roadmap
Your current SAP system is a dependable, hard-working vehicle that has kept your business moving. Moving to S/4HANA and SAP RISE is the natural evolution to a cleaner, safer, and far more efficient future. Follow this 12-step S/4HANA migration security roadmap along the highway to navigate the journey, avoid pricing potholes, and keep your landscape in peak condition.
The Evolution to a Cleaner, Safer SAP Fleet
Why building an S/4HANA migration security roadmap helps you take a dependable SAP estate from okay to better, better still, and continually striving for the best.
Think of your current SAP system like a trusty, reliable family estate car. It has served your business faithfully for years, carrying your orders, finances, and supply chain across thousands of miles. It runs reasonably well, gets your team where they need to go, and does a dependable job. But automotive technology moves on, and SAP is evolving rapidly. Moving to S/4HANA and SAP RISE is the natural next step. It is like stepping into a modern, whisper-quiet vehicle that is cleaner, safer, and far more efficient to run.
Respecting Where You Are While Striving for the Best
This journey is not about saying your current setup is bad. It is about taking an engine that has been okay and making it better, better still, and constantly striving for the absolute best. A practical S/4HANA migration security roadmap ensures you do not bring along old, unnecessary clutter in the boot that slows you down or triggers expensive cloud tolls.
To fund exciting future projects, businesses need to manage their daily running costs carefully. Every pound saved on unnecessary licences or bloated computing fees is fuel you can pour straight back into growing the business. At the same time, your S/4HANA migration security roadmap must tackle dual protection: you must protect your vehicle from within against those already inside by stopping accidental errors or internal fraud, while defending from within against outside threats trying to get in through unmonitored digital connections.
Natural Permission Drift
Over ten or fifteen years of business growth, staff pick up extra keys whenever they change desks or cover for someone on holiday. Over time, extra items gather in the boot. Cleaning these out before migrating keeps your new cloud vehicle agile, fast, and economical.
FUE Pricing Alignment
Under SAP RISE, licensing is object-based. If a user holds a single stray transaction code to approve purchase orders, SAP automatically bills them at the top-tier Advanced rate (1.0 FUE) instead of the Core rate (0.2 FUE). Aligning access to real tasks ensures you pay the correct toll.
Segregation of Duties Balance
You would not want both the driver and passenger having separate brake pedals fighting for control. When someone holds access to create a supplier and pay them, it creates unintended risk. Balancing these roles protects staff and gives external auditors total peace of mind.
Digital Access Transparency
When external web shops, warehouse scanners, or automated bots connect to your SAP engine in the background, SAP counts this as Digital Access. Proper trip monitoring ensures you track document counts accurately, avoiding unexpected surprise invoices down the road.
The 12-Step S/4HANA Migration Security Roadmap
The definitive S/4HANA migration security roadmap to make your estate clean, migrate it clean, and keep it clean for the open road ahead.
Look Under the Bonnet
Before setting off on any long journey, you need an honest view of how the engine runs. Capture and compress standard system execution logs to see what transactions your team genuinely uses every day.
Empty the Boot Clutter
Review your user directory for leavers, locked accounts, and dormant users who have not logged in for months. Safely reclaim their commercial licences so they return to your available pool.
Right-Size Your Road Tax
Evaluate real user behaviour through a 5-Gate behavioural waterfall. Prove mathematically which users only need low-cost Core or Self-Service tiers, dropping them to their lowest legitimate tier.
Check the Digital Towbar
When outside web shops, warehouse barcode scanners, and automated bots plug into your system, SAP charges for every record they create. Cortex ECHO tracks all 9 licensable document categories (Sales Orders, Invoices, Purchase Orders, Service and Maintenance, Manufacturing Orders, Quality Management, Time Sheets, Financial Documents, and Material Documents) and filters out duplicate background records so you are never billed twice.
Modernise the Transmission
Older ECC transaction codes change when you move to S/4HANA. Automatically map outdated screens into modern Fiori web apps, catalogues, spaces, and pages without manual translation headaches.
Build Clean, Lean Roles
Group staff doing similar jobs into clean, position-based roles based on actual execution logs. Build roles that grant only what users need to do their jobs, avoiding future role bloat.
Uncouple the Dual Pedals
Before deploying roles, run pre-emptive Segregation of Duties checks. Balance conflicting combinations like creating a vendor and paying them, ensuring roles are clean by design.
Test Drive in the Background
Traditional role testing can disrupt busy business teams. Run background shadow testing using live tracing to validate new security profiles while employees continue their daily work as normal.
Lock in Your Running Costs
Before signing your final RISE agreement, model your exact break-even price. Compare legacy spend against mathematical FUE weights to negotiate a contract matching true operational needs.
Enforce Smart Key Access
Automate user joiners, movers, and leavers through a governed four-eyes Decision Hub. Automatically expire temporary roles so dead permissions never linger in user accounts.
Emergency Pitstop Controls
When production issues strike, grant time-boxed Firefighter access that automatically cuts off when the clock runs down. Simultaneously monitor audit logs for suspicious activity.
The Master Dashcam & Sat-Nav
Unify licensing, security, and risk data across Production, QA, and Development into a single master cockpit. Maintain a permanent, tamper-proof audit ledger of every single change.
The CORTEX Suite by Tango Technologies

What You Could Unlock: Real Cost Savings and Peace of Mind
Whether you run a mid-sized team of 500 staff or a global enterprise of 7,000, cleaning your system before you sign your cloud agreement saves real money and protects your brand.
Mid-Market Operation (500 SAP Users)
When you have 500 staff using SAP, permission clutter builds up quickly over the years. People change jobs, cover for colleagues, or leave the company without their keys being taken back. Cortex cleans up the estate so you only pay for what people actually do.
- Secure: Strips away dead accounts and removes dangerous master keys so ex-employees or casual users cannot access sensitive business data.
- Compliant: Uncouples risky permission combinations so no single person can create a supplier and pay the invoice themselves.
- Efficient: Drops 32 Full Usage Equivalent (FUE) licences down to lower cost tiers because staff only carry out standard everyday tasks.
- Automated: Replaces messy manual spreadsheets with smart software checks that keep accounts tidy automatically.
- Audit Ready: Every single permission change is stamped into a clean digital ledger, giving auditors complete proof and giving you brand safety.
Global Enterprise (7,000 SAP Users)
Running 7,000 users across multiple factories and global offices usually means ten or fifteen years of accumulated permission bloat. Cortex analyses actual day-to-day usage to stop massive cloud over-spending and protect your company name.
- Secure: Defends against internal fraud and stops external digital threats before they can reach your core financial systems.
- Compliant: Cleans up hundreds of toxic access combinations across linked international systems without halting busy production lines.
- Efficient: Saves £1.45M across your multi-year cloud contract by proving mathematically that thousands of users only need standard operational tiers.
- Automated: Runs automated joiner, mover, and leaver routines with time-bound emergency access that cuts off on schedule.
- Audit Ready: Boardroom clarity and bulletproof audit records that keep your company name off the front pages and protect brand safety.
