Prevent Accidental Sending & Sharing

Have you ever accidentally sent important documents like proposals or quotes to the wrong business partner?

About 30% of corporate information leaks are caused by human errors such as mistaken sending.

List of Externally Shared Files

Quickly check who is sharing files externally and for what purpose.
Immediate Sharing Stop

While direct email attachments cannot be recalled after mistaken sending, Cloud Linker allows instant stopping of sharing by disabling shared document URLs.
Automatic Malware Scan

PDFs uploaded to Cloud Linker are instantly and automatically scanned for malware. Only files deemed safe through malware scanning can be shared externally, ensuring safe document exchange for both parties.

Manage All Externally Shared Documents Here

Recipients can safely receive documents even without a SIGQ Cloud Linker account.

You can centrally manage documents to be shared.

Easy to use with no complex settings required, it's a reliable partner that significantly improves daily work efficiency while securely protecting important data - something you can try with peace of mind.
