Zyxel SecuExtender SSL VPN Client [macOS and Windows] - Upgrade Options for EOL SecuExtender SSL VPN Client

We want to inform you that the SecuExtender SSL VPN macOS and Windows clients have reached their end of life (EOL). Zyxel is no longer selling, maintaining or supporting these products.

However, for those who recently purchased a license, we understand that you may still need access to the software. You can download the software using the archive links below:

• [macOS SecuExtender SSL VPN client 1.2.6]
• [Windows SecuExtender SSL VPN client 4.0.5.0] 
   

Option 1. Use IPSec VPN instead of SSL VPN

IPSec VPN is widely supported across all Zyxel firewalls and endpoint platforms, including macOS, iOS, Windows, and Android. It offers several advantages over SSL VPN:

• High Security: IPSec VPN uses multiple encryption and authentication methods, providing strong security and reducing the likelihood of web attacks like cross-site scripting.
• High Performance: IPSec VPN often outperforms SSL VPN, depending on application and connection conditions.
• Network Layer Encryption: Encrypts at the network layer, making it transparent to applications. However, setting up and managing IPSec VPN requires higher technical knowledge. In Zyxel, we aimed to simplify the process of provisioning an IPSec VPN client with a remote VPN wizard (on-prem mode) or using Nebula to generate VPN scripts in just a few clicks.

Alternatively, if you prefer to use free, built-in VPN clients, you can generate VPN scripts via Zyxel's VPN wizard or Nebula’s portal. These scripts are compatible with multiple platforms, including macOS, iOS, Windows, and Android (StrongSwan).

Option 2. Upgrade to USG FLEX H firewall to continue using SSL VPN

You may encounter firewall penetration issues when using IPSec VPN in rare conditions. SSL VPN uses HTTPS traffic, making it easier to penetrate firewalls and proxies. For further enhanced protection and comprehensive service features, consider upgrading to a USG FLEX H firewall that supports both IPSec and SSL VPN (OpenVPN). The latest generation solutions offer robust security measures and advanced capabilities to meet your evolving needs. Zyxel's new SecuExtender Zero Trust IPSec/SSL VPN Client supports both IPSec and SSL VPN protocol, plus advanced features: bandwidth throttling, easy provisioning, and tunnel redundancy.
