Illustration of AES-256 encryption in transit

Encryption in transit (AES-256 + TLS 1.3)

Why: Your data travels over the Internet and can be intercepted on public networks (WiFi, hotspots). How: FileVert automatically encrypts all your files with AES-256 (banking standard) during transfer and uses TLS 1.3 for connections. No action required: it's enabled by default on all your transfers.

  • Automatic AES-256 encryption (banking standard)
  • Secure TLS 1.3 connections
  • Automatic activation, no configuration required
  • Protection against interception on public networks

Frequently asked security questions

Everything about secure file transfer

During upload, check the "Password protection" option. Create a strong password (FileVert automatically verifies strength). Then share the link AND password separately (via SMS, phone call, or secure messaging) for maximum security.
During upload, enable the "Direct deletion" option (auto_remove). The file will be automatically deleted after the first successful download, with no possibility of re-download. Ideal for ultra-confidential documents.
During upload, enable "Private transfer" (for_team), select authorized team members by email, then create the transfer. Only selected members will be able to download files, even with the link.
Create a Pro Hub from your dashboard, enable "Private mode" (single_reception_mode) during creation. Share the Hub link with your clients. All deposited files will be automatically private and accessible only by you.
Yes! FileVert automatically encrypts all your files with AES-256 (banking standard) during transfer and uses TLS 1.3 for connections. No action required: it's enabled by default on all your transfers.
The anti-phishing badge system automatically displays the sender's expertise level on each download link. Badges are awarded based on training and usage (Lvl. 1-2: Identified account, Lvl. 3-5: Active Pro, Lvl. 6+: Expert, Max: Ambassador).
Antivirus scanning is automatic and transparent. All files are analyzed with ClamAV (signature detection) before being made downloadable. If a virus is detected, the file is blocked and the recipient is warned. No action required on your part.
Custom links (public DNS per client) create predictable paths and increase the risk of targeted attacks. FileVert uses the filevert.fr domain with secure encoding to ensure there is no specific path to target a particular client, strengthening overall security.
