Send confidential files.
Know exactly who opened them.
FileLink is identity-verified file sharing for the moments a normal email attachment is too risky — NDAs, board packs, investor updates, HR records, and vendor due diligence. Every recipient verifies with a one-time password before they see anything. Every view, print, and download attempt is logged — and if it ever leaks, dynamic watermarking traces it back.
The problem with “just email it.”
Once an attachment leaves your outbox, it can be forwarded, copied, and stored forever by anyone it reaches. You can't take it back, you don't know where it ended up, and if it surfaces somewhere it shouldn't, there's no way to trace how it got there. For confidential documents, that's not a workflow gap — it's exposure with no way to undo it.
Identity-verified, revocable, traceable.
Identity-verified access
One-time password verification before a file ever loads.
NDA gating
Require a signed NDA or disclaimer before access, with a timestamped acceptance log.
Dynamic watermarking
Every page is watermarked with the viewer’s identity — a leak traces back to who had it.
FolderLinks for external sharing
Share a whole folder with the same access rules applied throughout, to anyone outside your team.
TeamDrives for your own team
A persistent, secure internal shared drive for your team’s own working files — separate from what you share externally.
Instant revocation, date/time-bound access
Cut off access the moment it’s no longer needed, or set it to expire automatically.
A secure viewer, not a download
Files stream in the browser. Download and print are off by default.
Engagement analytics
See who opened a document, when, and how long they spent on each page.
Full audit trail
Every access, print attempt, and download logged and exportable.
Works everywhere
Paste a FileLink into WhatsApp, Telegram, Slack, or anywhere else your team already communicates — the file itself never leaves FileLink’s control. See how →
Six non-negotiables.
No AI
No model ever reads, summarizes, indexes, or trains on your files.
No Third-Party Risk
No embedded plugins, no third-party storage layers, no silent data-sharing agreements.
No Software, No Installs
Sender and recipient both work entirely in the browser.
End-to-End Encrypted
Encrypted in transit and at rest, decryptable only by verified parties.
No Trace on the Device
Streamed to a secure viewer, never copied to disk.
Full Control, Anytime
Revoke instantly or schedule expiry, even after it’s been viewed.
Five steps. Total control.
Upload
Single file or full folder with subfolders. Encrypted the moment it leaves your browser.
Set the rules
OTP required, NDA gate, dynamic watermark, download blocked, expiry timer — you decide.
Share the link
Send via email, WhatsApp, or SMS. No recipient account, no app, no install.
Track everything
Real-time open alerts plus per-page dwell analytics. Know exactly who engaged and how.
Revoke anytime
Instant or scheduled. Access ends immediately — even after the file has been viewed.
Receiving confidential files is just as risky as sending them.
Every other tool focuses on sending. But inbound files — vendor documents, KYC packets, legal case files — carry the same risk. FileLink lets you generate OTP-verified upload links so files arrive encrypted and tracked.
See Secure ReceivingCreate a receive link
Generate an OTP-verified upload request. The sender gets a link — no account, no app.
Sender verifies identity
The sender enters a one-time password sent to their email before they can upload.
File arrives encrypted
Files are encrypted in transit and at rest. They land in your secure workspace, not an inbox.
You review in the viewer
Open files in the streamed viewer — never downloaded. Full audit trail for every submission.
Everything you need to share files securely
OTP Recipient Authentication
Anyone opening a FileLink link verifies their identity with a one-time password before the file loads. You know exactly who opened it and when.
NDA Gating
Require a custom NDA or disclaimer to be read and accepted before access is granted. Every acceptance is timestamped and logged with IP.
Dynamic Watermarking
Every page a recipient views is watermarked with their identity. If a document ends up somewhere it shouldn’t, the leak traces back to exactly who had access.
FolderLinks — External Folder Sharing
Share an entire folder structure with people outside your team as a single link, with OTP, NDA gating, watermarking, and permissions applied throughout.
TeamDrives — Internal Team Workspace
A persistent, secure shared drive for your own team members to store and access working files internally, distinct from what you share externally.
Instant or Scheduled Revocation
Cut off access instantly, or set a link to expire on a specific date and time. Even after someone has opened the file, you can pull it back.
Granular Access Controls
Per-recipient, per-link: view only, download allowed or blocked, print allowed or blocked, resharing allowed or blocked.
Secure File Viewer
Files render in the browser. Nothing written to the recipient’s device by default — zero device footprint, no trace, no leftover.
Engagement Analytics
See who opened a document, when, and how long they spent on each page — follow-up based on data, not guesswork.
Instant Email Alerts
Get notified the moment a file is opened. Know when to follow up — and when to worry.
Real-Time Audit Trail
Every access, verification, view, print, or download attempt logged with timestamp, IP, device, and location — exportable for compliance.
Share Anywhere
FileLink isn’t tied to email. Paste the link into WhatsApp, Telegram, Slack, Teams, or SMS — every recipient still goes through OTP verification, NDA gating, and the secure viewer, no matter which app carried the link.
Trusted by people who can’t afford a leak
“We used to email board packs as password-protected PDFs. Two directors lost the password and one forwarded it to a personal account by mistake. With FileLink, we know exactly who opened it, when, and from where. Nobody has a copy on their laptop.”
Rajat Khanna
CFO, mid-sized manufacturing company
“Our due diligence room used to take a week to set up and cost thousands per deal. For vendor onboarding, FileLink is enough. OTP verification, audit trail, and we revoke access the moment diligence closes. The vendors don't need to install anything.”
Priya Nair
Head of Procurement, enterprise SaaS company
“I share pitch decks to investors regularly. Before, I had no idea if they actually read it or just said they did. Now I see page-level dwell time. One investor spent 22 minutes on the financials slide. That's the person I called first.”
Vikram Rao
Founder, early-stage B2B startup
“As a law firm, chain of custody matters. Every NDA we send through FileLink has the recipient's email watermarked on every page. If something leaks, we know exactly whose copy it was. The access logs are detailed enough for litigation.”
Shreya Gupta
Partner, boutique corporate law firm
“Collecting KYC documents from new hires used to mean back-and-forth email attachments. Now we send one secure upload link. The candidate verifies with OTP, uploads their documents, and everything lands in our workspace encrypted. No more lost ID copies.”
Amit Sharma
HR Director, growing tech company
“I was skeptical about another file-sharing tool. But the no-AI thing sold me. We handle client financials — the last thing I need is some model indexing them for "smart features." FileLink just shares the file securely and gets out of the way.”

Controller, regional accounting firm
