How to choose, use and configure a VPN in Securepoint Security Suite (Tutorial)

Best VPN Clients for Securepoint Security Suite

Securepoint Security Suite is a Debian-based distribution tailored for corporate security gateways and workstation protection. It relies on apt as its package manager, uses systemd for service orchestration and typically ships with lightweight desktop environments such as Xfce or KDE Plasma for on-site management consoles. Its primary audience comprises system administrators and security-conscious power users who need rock-solid firewall, antivirus and VPN integration without the bloat.

When choosing a VPN client for this environment, you need packages that:

Integrate cleanly with apt repositories and systemd services.
Offer both CLI and (optionally) GUI front ends compatible with Xfce/KDE.
Support modern protocols (WireGuard, OpenVPN) plus robust DNS/security features.
Provide official Linux support and timely security updates.

Based on those criteria, these three VPNs stand out:

ProtonVPN – Official Debian repo, CLI amp GUI, strong privacy focus.
NordVPN – Easy install script, CLI tool, autoswitch features.
Mullvad – Supports both OpenVPN amp WireGuard, provides a native Debian package.
