What Is Synthesia AI?
Synthesia AI is a leading synthetic media generation platform that creates professional videos with AI avatars from text scripts. Users can generate training videos, marketing content, and educational materials in 120+ languages without cameras, actors, or studios. In 2025, it has become essential for corporate communications, e-learning, and global content localization.
However, creating these videos involves uploading scripts, proprietary business information, and sometimes custom avatars to cloud servers—making network-level security critical.

Why You Need a VPN for Synthesia AI
Protecting confidential scripts
Your video scripts may contain proprietary training materials, internal policies, or unreleased product information. On public Wi-Fi, this data is vulnerable to interception.
Securing custom avatar uploads
When you upload personal video to create a custom AI avatar, you're sharing biometric data. VPN encryption prevents this sensitive media from being intercepted.
Bypassing network restrictions
Many corporate networks block AI video platforms. A VPN masks your traffic as standard HTTPS, restoring access to Synthesia.
Eliminating ISP throttling
Internet providers often slow down video-heavy services. A VPN removes these artificial speed limitations for faster avatar rendering and video generation.
Accessing regional voice avatars
Some AI voices and avatars are restricted by region. Important: bypassing these may violate ToS.
Target Audience: Who Needs VPN for Synthesia
1. Corporate trainers and HR teams
Problem: Creating internal training videos with sensitive company information on public networks.
Solution: VPN encrypts all scripts and generated videos.
2. Marketing agencies
Problem: Producing client campaigns containing confidential brand strategies.
Solution: VPN protects proprietary marketing concepts.
3. Educational institutions
Problem: Developing e-learning content in university networks that block AI tools.
