This policy has been independently audited by the renowned security firm Cure53 and published with a complete report, ensuring every commitment stands up to scrutiny.
Millisecond-Level Smart Connection
Kuainiu Accelerator's intelligent routing engine continuously monitors global node latency and load, automatically matching you to the optimal pathway. With a single click, achieve latencies as low as 15ms, ensuring smooth, uninterrupted experiences for video conferences, online gaming, or 4K streaming.
Coverage in Over 80 Countries
Kuainiu Accelerator has over 3000 high-speed servers deployed across more than 80 countries, including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server runs in pure RAM mode, erasing all data upon reboot, eliminating any possibility of data retention from a hardware level.
One Account, 6 Devices Online
With a single Kuainiu Accelerator account, you can simultaneously protect your phone, computer, tablet, smart TV, and router—allowing up to 6 devices to connect at once, sharing a secure network for the entire family without additional fees. After configuring a router, you can even protect IoT devices that do not support accelerators.
24/7 Professional Customer Support
Kuainiu Accelerator boasts a bilingual customer support team fluent in both Chinese and English, providing round-the-clock assistance. Whether you need help with installation, connection issues, or account management, you can get immediate, professional help through live chat or email, with an average response time of under 2 minutes.
In-Depth Analysis of Protocol Technology
Discover how the cutting-edge routing protocols utilized by Kuainiu Accelerator provide you with unparalleled speed and security.
WireGuard Core Architecture
Kuainiu Accelerator has constructed an entirely new routing engine based on the WireGuard protocol. WireGuard achieves complete accelerator functionality with approximately 4000 lines of code, whereas traditional IPsec requires over 600,000 lines. The streamlined code results in a smaller attack surface, lower latency, and higher throughput. In our internal testing, WireGuard's handshake speed is 3 times faster than IKEv2 and 8 times faster than IPsec.
Noise Protocol Framework Encryption
Kuainiu Accelerator's implementation of WireGuard employs the Noise protocol framework for key exchanges, utilizing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been widely validated in both academia and industry, offering forward-looking security against quantum computing attacks.
Intelligent Protocol Switching
In certain network environments, WireGuard's UDP traffic may be restricted. Kuainiu Accelerator includes an intelligent protocol switching feature that can automatically detect network conditions and seamlessly switch between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring stable connections in any environment. The entire switching process is completed within 500 milliseconds, making it nearly imperceptible to the user.
Multi-Hop and split routing
Kuainiu Accelerator supports multi-hop connections, allowing data to be relayed through two or more acceleration servers, providing an extra layer of privacy for users who require complete anonymity. Meanwhile, the split routing feature allows you to choose which applications use the accelerator and which connect to the local network directly, achieving the best balance between performance and security.
Encryption and Privacy Protection
Multi-layer encryption techniques combined with a strict privacy policy offer comprehensive protection for your digital life.
AES-256-GCM Encryption Standard
Kuainiu Accelerator employs the AES-256-GCM encryption mode for all transmitted data. AES-256 is currently the encryption standard approved by the NSA for protecting top-secret information. Even with the most powerful supercomputers currently available, cracking it would take billions of years. A unique session key is generated for every connection, ensuring forward secrecy.
DNS Leak Protection
Kuainiu Accelerator operates its own private DNS server cluster, ensuring that all DNS queries are resolved through encrypted connections, thus eliminating the risk of DNS leaks. We also incorporate WebRTC leak protection and IPv6 leak protection features, ensuring that your real IP address is never exposed under any circumstances. You can always verify your protection status using the built-in leak testing tool.
Kill Switch
Kuainiu Accelerator's Kill Switch feature instantly cuts off all internet traffic if the acceleration connection unexpectedly drops, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: the system-level mode protects all traffic, while the application-level mode only secures specified applications, giving users optimal flexibility.
RAM-Only Pure Memory Servers
All of Kuainiu Accelerator's 3000+ servers operate in pure RAM mode. This means that no hard drives exist on the servers, and all data is processed solely in memory. Each time the server reboots, all data is completely wiped. This is the highest standard of data protection in the industry.
Streaming and Entertainment Optimization
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy global content seamlessly.
4K Ultra HD Streaming Support
Kuainiu Accelerator's high-speed nodes are specifically optimized to reliably support the bandwidth demands of 4K Ultra HD (2160p) video streaming. Whether watching feature films, live sports events, or music videos, Kuainiu Accelerator delivers a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently exceed 500Mbps.
Gaming Acceleration and Low Latency
Kuainiu Accelerator has been specially optimized for online gaming. Our intelligent routing engine automatically selects the pathways with the lowest latency to game servers. In our tests, the latency to Asia-Pacific game servers was as low as 10ms, and 60ms to North American servers. DDoS protection prevents malicious attacks during gameplay.
P2P and Torrent Download Optimization
Kuainiu Accelerator has enabled P2P optimization on nodes in over 30 countries worldwide. We do not restrict the bandwidth or speed of P2P protocols like BitTorrent, while encrypting your downloading activities to protect them from ISP monitoring and throttling. The port forwarding feature enhances seeding efficiency, supporting faster upload speeds.
Smart Content Acceleration Technology
Kuainiu Accelerator's exclusive SmartRoute technology intelligently identifies the type of content you are accessing and automatically selects the optimal transmission path. It switches to streaming-optimized nodes when watching videos, to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes for browsing. The entire process is fully automated, requiring no manual intervention.
