Vendor Due Diligence

Vendor due diligence with a full audit trail.

Vendor onboarding means collecting security questionnaires, compliance certificates, financial statements, and legal documents from external parties. The usual process — email back-and-forth with attachments — is slow, untraceable, and risky. FileLink gives each vendor a secure upload link with OTP verification. They upload through a portal, files arrive encrypted, and you maintain an audit trail that satisfies ISO 27001 and SOC 2 auditors. When diligence closes, you revoke access. Every submission is accounted for.

The problem today

Vendor documents collected via email — no access control or audit trail

Cannot prove when documents were received or who submitted them

Files sit in shared inboxes accessible to anyone with inbox access

No way to revoke access to submitted documents after diligence closes

How it works

STEP 1

Create a receive link

Generate an OTP-verified upload request. The sender gets a link — no account, no app.

STEP 2

Sender verifies identity

The sender enters a one-time password sent to their email before they can upload.

STEP 3

File arrives encrypted

Files are encrypted in transit and at rest. They land in your secure workspace, not an inbox.

STEP 4

You review in the viewer

Open files in the streamed viewer — never downloaded. Full audit trail for every submission.

What you get with FileLink

Per-vendor OTP verification

Each vendor verifies identity before uploading. You know exactly who submitted each file.

Compliance-ready audit trail

Every submission logged with sender, IP, device, and timestamp. Satisfies auditor requirements.

Revocation after closure

Revoke access to all vendor documents the moment diligence closes. No lingering access.

Enforced deadlines

Set expiry on upload links. Vendors cannot submit after the deadline passes.
