Sound familiar?

You’ve had this afternoon before.

Tender day

“Submission closes at 5pm. The package is 380 MB. The portal takes 25.”

→Give it the limit, hand it the folder, get an upload-ready package with the spreadsheet logic intact.

The bounced email

“Your message couldn’t be delivered. Attachment exceeds 20 MB.”

→Shrink it to attachable and just send the file. No link, no login, no third party holding a copy.

The redaction

“Take the account number out before this goes to the other side.”

→The characters leave the file, then the saved output is reopened and searched to prove it.

Next How the security holds up Offline by architecture, verified redaction, and a statement written for vendor assessments.
