Protecting data in Excel: Data protection in Excel reimagined – without insecure password solutions!

Data protection in Excel reimagined: Don't rely on spreadsheet passwords anymore, as they are no longer a reliable form of protection. When it comes to sensitive data, you need more than just access restrictions. With IRI CellShield, you can take data protection in Microsoft Excel to a whole new level – effective, controllable and seamlessly integrated into your familiar working environment.

Protect sensitive data – without rendering it unusable!

Instead of simply locking information, you can mask critical content in a targeted and rule-based manner. Realistic but fictitious replacement values ensure that your spreadsheets can still be used for testing, analysis, development and data exchange – without revealing genuine personal or business-critical content.

Your advantages with CellShield:

1. Automatic detection and classification of sensitive data – even across tables
2. Flexible protection methods such as encryption, blacking out, pseudonymisation or hashing
3. Granular key management for maximum control and access exclusively by authorised users
4. Seamless integration into Excel – no system changes, no media breaks, no additional training required

More security. Same workflow.

All functions are available directly in Excel. Your workflow remains unchanged – but your sensitive data is technically secured, protected in compliance with regulations and controllable at all times.

If you wish, I can tailor the text even more closely to a specific target group (e.g. data protection officers, IT management, specialist departments or healthcare context).
