What is the Safest Way to Send Large Video Files to Clients?

"Safest" is not one thing. Sending a 40 GB rushes folder for an unannounced product launch is a different problem from sending a wedding edit to a couple. So rather than crowning one winner, here is what actually goes wrong, and the checklist that prevents it.

The four ways deliveries leak

1. The link outlives the job. A share link with no expiry is still live years later, indexed in someone's inbox, forwardable by anyone who ever received it.
2. Over-broad permissions. "Anyone with the link can edit" on a folder that also contains the previous client's material.
3. Forwarding. Your client CCs a contractor, who CCs a friend. Nothing was hacked; the link simply travelled.
4. The wrong recipient. Autocomplete picks the similar address. This is the most common real world breach, by a mile.

Notice that none of these are broken encryption. They are retention and access problems, so that is where your effort belongs.

Why the usual options fall short

Email attachments. Capped at 25 MB on most providers, so irrelevant for video. Worse, attachments live forever in mail archives you do not control.

Consumer cloud drives. Excellent for collaboration, poor for delivery. Permissions are sticky, links default to permanent, and folder structures leak neighbouring clients.

Standard transfer services. Right shape — upload, link, expiry — but usually flat monthly pricing, often no expiry control on the free tier, and typically no password on the download itself.

Physical drives. Genuinely secure in transit if encrypted, genuinely awful if the courier loses it. Fine for 40 TB archives, absurd for a 6 GB cut.

The checklist that actually keeps a delivery safe

• Set an expiry before you send. Three to seven days. The single highest impact control there is.
• Password protect the package when the material is sensitive, and send the password over a different channel — WhatsApp, a phone call, anything that is not the same email thread.
• Send to named recipients, not a link pasted in a group chat.
• Check the address twice. Read it out loud. Autocomplete is where deliveries go wrong.
• Verify the download, then delete. A transfer that has been collected should not still exist.
• Never reuse one folder for multiple clients. One delivery, one container.
• Write your retention rule into your terms so clients are not surprised when the link dies.

How Shako implements that checklist

We designed Shako around the failure modes above rather than around storage size:

• Encrypted in transit and at rest, over HTTPS throughout.
• Malware scanned on upload, so you are not the vector.
• Random, unguessable links — nothing sequential, nothing enumerable.
• Short lived signed download URLs, so a copied URL does not become a permanent open door.
• Retention you choose, priced by the day, with credits returned when you clear early.
• Password protected ZIPs that stay compatible with the unzip tool already on your client's machine. We never store or email the password — it is shown to you once, to pass on however you like.
• Delete on demand, with a short grace window in case you delete the wrong thing.

We are deliberate about what we do not claim: Shako is not end to end encrypted, because we scan for malware and package files server side. Anyone promising both at once is selling you something. For most client work, encrypted transit and storage plus short retention plus a password is the right trade — and it is far stronger than an indefinite drive link, which is what it is usually replacing.

Matching the method to the material

The one habit that matters most

Shorter retention beats every other control. A file that no longer exists cannot be forwarded, indexed, subpoenaed or leaked. That is why our pricing charges by days kept and pays you back for clearing early — the safe habit and the cheap habit are the same habit.
