Why anonymise your data?
Anonymisation is an essential step in protecting privacy, limiting the risk of data leakage and complying with regulations such as the RGPD. By eliminating any possibility of personal identification, you secure your data while retaining its value for analysis, development or research. It's also a strategic lever for sharing, testing or exploiting your databases with complete peace of mind, without compromising confidentiality or compliance.

A driver of growth
|
Avant NymData Sensitive data brake |
Après NymData Growth lever |
| Sensitive data cannot be shared -> legal risks and GDPR | Anonymised data circulates freely between teams, subsidiaries and partners, without risk. |
| Statistical analysis is limited -> fear of exploiting customer data | Les données sont exploitables pour créer des tableaux de bord et piloter la performance |
| AI/ML projects are being held back -> impossible to use real data safely | Models can be trained on realistic and secure data. |
| Legal constraints block any possibility of internationalisation. | Compliance is built in, enabling the company to expand into new markets. |
| Much of the data remains unused. | Data is becoming a strategic resource for innovation and growth. |
