What are VPNs and VPN gateways?

VPN (Virtual Private Network): Connects your device to a remote server through an encrypted tunnel, hiding your real IP address and protecting data transmission. Common products include ExpressVPN, NordVPN, Surfshark, and other major international providers.
VPN gateway: A colloquial term in the circumvention community, referring to subscription-based proxy node services that provide protocols such as Shadowsocks (SS/SSR), V2Ray (VMess/VLESS), Trojan, Hysteria, etc. Users purchase subscription links and import them into clients like Clash, Shadowrocket, V2rayN, etc. Named because early Shadowsocks clients had icons resembling small airplanes.
Both can achieve the goals of hiding IP addresses and bypassing censorship, but they differ significantly in underlying technology, applicable scenarios, and user experience.
Core comparison between VPN and VPN gateway
Below is a detailed comparison of the two on key indicators:
Nature and Protocols
VPN uses end-to-end encrypted tunnels (such as WireGuard, OpenVPN, IKEv2), offering high security; VPN gateways use lightweight proxy protocols (like Trojan disguised as HTTPS, VLESS+WS+TLS), focusing more on speed and anti-blocking.
Speed and Stability
VPN gateways are usually faster with lower latency, suitable for 4K videos, AI tools, gaming, and other heavy usage. VPNs, due to strong encryption, have higher overhead and slightly slower speeds, but can meet daily needs with optimized nodes.
Security and Privacy
VPN has clear advantages: full traffic encryption, no-logs policies (verified through independent audits), Kill Switch disconnection protection, suitable for handling financial, sensitive information, or public Wi-Fi scenarios. VPN gateways have relatively simple encryption; providers can theoretically see some traffic, offering moderate privacy protection.
Ease of Use
VPN wins: official apps allow one-click connection, friendly for beginners. VPN gateways require configuring third-party clients, with a steeper learning curve, but offer more powerful rule-based traffic diversion.
Price and Cost-Effectiveness
VPN monthly fees are usually above 20-50 yuan; VPN gateways are more cost-effective, offering massive traffic (hundreds of GB to TB scale) and numerous nodes for just a few yuan to dozens of yuan.
Anti-censorship Capability
In complex network environments in mainland China, VPN gateways using Trojan/V2Ray protocols have stronger disguise capabilities and flexible node switching. VPNs rely on obfuscation servers; some major providers have China-optimized servers, but their effectiveness fluctuates with GFW upgrades.
Nodes and Flexibility
VPN gateways have many nodes (Hong Kong, Japan, Singapore, US, etc.) supporting complex rule-based routing (direct connection within China, foreign proxies). VPN nodes cover the globe but are fewer in number, often more specialized for streaming services like Netflix.
Risks and Reliability
VPNs operated by reputable companies have low risk of shutdown and good customer support. VPN gateways are often run by individuals or small teams; during sensitive periods, nodes may crash or services may be interrupted, requiring multiple subscriptions as backups.
Advantages of VPNs in specific scenarios
Beginners or occasional travelers abroad.
Prioritize privacy and security (e.g., stock trading, banking, content creation involving sensitive topics).
Require stable one-click experience and additional features (ad blocking, Double VPN).
Corporate remote work or long-term overseas use.
Recommended: ExpressVPN (easy and stable), NordVPN (feature-rich), Mullvad (extreme privacy).
Advantages of VPN gateways in specific scenarios
Long-term heavy circumvention users in mainland China.
Pursue extreme speed and cost-effectiveness (e.g., ChatGPT, TikTok, short video creation, AI generation).
Need fine-grained rule-based routing and frequent node switching.
Budget-conscious but technically capable older users.
