The Zero Trust Guide to File Sharing: Why Cloud Links Are Dangerous
A simple cloud link can quietly expose data far beyond its intended audience.
In our digital-first world, file sharing’s convenience often sacrifices security. The core principle of Zero Trust is simple: Never trust, always verify. This approach ensures that shared cloud links, the keys to your data, adhere to strict security protocols to prevent unintentional data leakage and security breaches.
❌ Problem #1: “Anyone With the Link”
Cloud links don’t know who is accessing the file.
If the link leaks, so does your data.
No login. No identity. No trust.
❌ Problem #2: Default “Edit” Access
Many links are shared with edit permissions by default.
One wrong click =
• file deleted
• data altered
• ransomware risk
❌ Problem #3: Links Don’t Expire
That link you shared last year?
Still active.
Still accessible.
Still risky.
Former employees, vendors, or unknown recipients may still have access.
❌ Problem #4: Links Travel Faster Than You Think
Links get forwarded in:
WhatsApp
Email threads
Slack
Screenshots
You lose visibility instantly.
🛡️ Final Thought
Cloud links are not evil —
blind trust is.
If you wouldn’t hand a file to a stranger,
don’t share a link that acts like one.
