Find out causes and possible solutions. ## Datafence menu not visible I can’t find the Datafence menu. #### Cause Datafence is available only to pre‑approved accounts. #### Solution If you want to use Datafence, please contact [[Customer Support]](https://www.ncloud.com/support/question/service){target="_blank"}. We will review your request and grant access as appropriate. ## External data export How is external data export controlled? #### Cause Datafence blocks external communications to enable secure collaborative analytics. Export of public data is only possible through the in‑product export request feature, which requires review by a Datafence administrator. #### Solution As described above, you can export data only through the export request feature with administrator review and approval. You can request up to 10 files at a time, and each file must be no larger than 2 GB. ## Create additional Datafence environments I want to create more than one Datafence. #### Cause For stable operations, each account can create only one Datafence. #### Solution As noted above, you can create only one Datafence per account. If you need more, we recommend using the Organization service: 1. Create a new NAVER Cloud Platform account. 2. Create Datafence in the additional account. 3. Link it to your master account using the Organization service. ## Learning resources We offer various materials for you to explore.
