Viscosity for Windows

Simple, Secure VPN Access with Viscosity

Viscosity is a Windows client for OpenVPN that makes creating encrypted internet connections straightforward. It uses SSL-based VPN tunnels to protect traffic and is suited for both personal and business use. The app is designed so users can connect securely without needing deep networking expertise.

Core advantages

• Clean, approachable interface that lowers the learning curve for new users.
• Support for managing many VPN profiles at once, so switching between networks is simple.
• Tools to bring in connection settings from other servers, which speeds up migration.
• Appearance controls and configurable idle-time disconnects to tailor the app to your workflow.
• Freely available to download and try, making it easy to evaluate before committing.

Setup and migration made easier

Importing existing configurations is one of Viscosity’s conveniences. If you’re moving from another VPN client or provisioning multiple endpoints, you can bring in server profiles and certificates to reduce manual setup. This is especially useful for administrators rolling out access across a team.

Personalization and session control

Viscosity includes options to customize how it looks and behaves. You can adjust visual elements to match preferences and enable an automatic disconnect after a set period of inactivity to help limit exposure when a session is left open.

Who benefits most

• Individuals who want a straightforward way to secure their internet traffic.
• Small businesses and IT teams that need to manage a handful or many VPN profiles.
• Users who prefer an intuitive client that doesn’t require deep command-line knowledge.
