OpenConnect GUI
OpenConnect GUI is an open-source SSL VPN client for Windows. It is compatible with Cisco AnyConnect and other SSL-VPN servers, providing a free alternative for secure and private connections.
It is especially useful when:
- You need to connect to Cisco AnyConnect-compatible VPNs
- You want an open-source client with a simple interface
- You use corporate or self-hosted VPN servers
- You need a fallback option when commercial VPN apps are blocked
Note: OpenConnect is a client only — you still need access to a VPN server.

FAQ
Is OpenConnect GUI compatible with Cisco AnyConnect?
Yes. It was designed as an open-source alternative to Cisco AnyConnect and works with most compatible VPN servers.
Does OpenConnect include a VPN service?
No. OpenConnect is only a client. You must already have access to a VPN server.
Is OpenConnect secure?
Yes. It uses SSL/TLS protocols for secure tunneling. Always verify your server settings and certificates.
Where can I find installation instructions?
See our Installation & Usage Guide (with screenshots).
Does OpenConnect support two-factor authentication (2FA/MFA)?
Yes. Many corporate AnyConnect servers use MFA (for example, OTP or push notifications). OpenConnect GUI prompts for additional factors during login, just like the official Cisco client.
Is OpenConnect faster than OpenVPN?
Performance depends on the server and protocol. OpenConnect is often comparable or faster than OpenVPN because it uses TLS/DTLS with UDP transport. For maximum speed and simplicity, WireGuard is usually faster, but not always supported in corporate environments.
Why choose OpenConnect over Cisco AnyConnect?
OpenConnect is open-source, free, and lightweight. Cisco AnyConnect is proprietary and sometimes restricted by licenses. Many admins prefer OpenConnect because it is auditable and not tied to a vendor ecosystem.
