Email attachments were never built for confidential work. Here is how to send sensitive documents securely, with encryption, access control and an audit trail, and the simplest way to do it.
Email was never built to move confidential documents safely. Standard attachments are not protected once they land, you lose all control after you hit send, and a 25 MB cap pushes people onto risky consumer tools. The secure way is to share a branded, encrypted link with expiry, password and an audit trail, so the file stays protected and you can prove who accessed it. Alkmist Share Space does exactly this: AES-256 encrypted links on your own domain, up to 5 GB, EU-hosted and ISO 27001 certified.
Four reasons sensitive documents should not travel as email attachments.
Standard email encrypts the connection, not the file at rest in every inbox it touches. Once a document is sent, you cannot expire it, revoke it, or control who it is forwarded to.
IBM's 2025 Cost of a Data Breach report puts phishing as the single most common entry point for breaches, and the global average breach now costs 4.44 million dollars. In the Benelux it is 6.24 million.
Gmail caps attachments at 25 MB and Outlook at around 20 MB, so people fall back to consumer tools or personal drives, scattering sensitive files outside any control.
Email gives you no audit trail. For regulated work you cannot prove who accessed a document, when, or whether it was downloaded.
A simple checklist that holds up to regulated, client-facing work.
Use a tool that encrypts documents at rest and in transit, like AES-256, so the file is protected the moment it leaves your hands.
Set link expiry, password protection and read receipts, so access ends when it should and you can see what happened.
Log who created, viewed, downloaded or revoked each file, and export it for auditors in one click.
A link on your own domain, in your own branding, reassures clients far more than a random consumer URL, and reduces risky hesitation.
Everything on the checklist, in one branded, compliant flow.
With Alkmist Share Space you send a file as a branded, AES-256 encrypted link instead of an attachment. Recipients get a clean download page on your domain, not a generic consumer tool.
Set link expiration (7 days, 30 days or indefinite), add optional password protection for extra-sensitive files, and get read receipts when a document is opened.
Send entire workpaper archives in one go, with no 25 MB email cap and no falling back to personal drives.
Every action is logged with timestamps and IPs, and you can export a compliance-ready report for auditors or regulators. EU-hosted, ISO 27001 certified, GDPR-aligned, never used to train AI.
