In the field of international scientific internet access and privacy protection, StrongVPN is a highly respected international VPN group with a long operational history. Despite the strict blockages imposed by the Great Firewall (GFW) on traditional protocols in recent years, StrongVPN still provides a robust backup connection channel during sensitive periods in mainland China, thanks to its unique Scramble feature obfuscation technology combined with the high-speed WireGuard protocol. Its most notable advantage is its highly cost-effective multi-device sharing support (allowing up to 12 devices online simultaneously), making it an ideal auxiliary solution for moderate users and multi-device disaster recovery backup groups.
Protocol and Obfuscation: OpenVPN Scramble & WireGuard Speed
Regarding transport-layer packet obfuscation, StrongVPN possesses two highly practical technical features:
- OpenVPN Scramble Handshake Obfuscation: This is the core technology that allows StrongVPN to survive in mainland China. In default mode, OpenVPN’s SSL handshake fingerprints are extremely conspicuous and blocked instantly by GFW. When Scramble obfuscation is enabled, the client adds a layer of randomized noise to the OpenVPN packet headers, successfully disguising the traffic as standard uncharacterized HTTPS encrypted streams. This significantly increases survival rates during high-pressure censorship periods.
- WireGuard Native Protocol Acceleration: During non-sensitive periods, StrongVPN supports native WireGuard connections. This protocol is exceptionally lightweight, consumes minimal system resources, and establishes handshakes rapidly. Tested on telecom and unicom broadband, downlinks easily reach 100M – 200M limits, providing a smooth streaming experience.
Multi-Device Connections and Cost-Effective Sharing
Among traditional international VPN providers, most limit simultaneous connections strictly. StrongVPN, however, is exceptionally generous:
- Support for Up to 12 Devices Simultaneously: This means a single account can cover an entire household, small studio, or multi-device tech setup without any concurrency limits.
- Global Server Coverage: High-speed physical servers in dozens of countries offer distinct clean IP advantages when unlocking geo-blocked streaming libraries.
Review Summary and Selection Advice
As a legacy international giant, StrongVPN may not be the primary choice for 24/7 heavy developmental tasks, but it is an exceedingly perfect multi-device backup solution. If your daily workflow heavily relies on premium channels like Astrill VPN and you need an affordable (averaging ~$3.66/month) backup connection that supports multiple devices, StrongVPN is a highly cost-effective cushion in your network inventory.
