Explore the core features and technology behind Comet Accelerator
| Feature | Details |
|---|---|
| Next-Gen WireGuard Protocol | Comet Accelerator fully integrates the WireGuard protocol, with just 1/100 the code of IPsec, yet delivering 3-5 times faster transmission speeds. The streamlined code translates to a smaller attack surface and heightened security, letting you enjoy top speeds without worrying about privacy breaches. |
| Audited No-Logs Policy | Comet Accelerator adheres to the strictest no-logs policy in the industry—no recording of connection times, websites visited, IP addresses, or any browsing data. This policy has been independently audited by the well-known security firm Cure53, with a full report available, ensuring that every commitment can withstand scrutiny. |
| Intelligent Connections in Milliseconds | Comet Accelerator’s intelligent routing engine monitors global node latency and load in real-time to automatically match you with the best connection. With a single click, experience latency as low as 15ms, whether for video conferencing, online gaming, or 4K streaming, ensuring a smooth experience without interruptions. |
| Nodes Across 80+ Countries | Comet Accelerator has deployed over 3000 high-speed servers in more than 80 countries and regions including North America, Europe, Asia-Pacific, South America, and the Middle East. Each server operates in pure RAM mode, erasing all data upon reboot, effectively eliminating any chance of data retention at the hardware level. |
| One Account for 6 Devices Online | With a single Comet Accelerator account, protect your phone, computer, tablet, smart TV, and router—connecting up to 6 devices simultaneously, sharing a secure network for the whole family without additional fees. Once configured on your router, you can even safeguard IoT devices that don’t support accelerators. |
| 24/7 Professional Customer Support | Comet Accelerator boasts a bilingual customer support team fluent in both Chinese and English, offering round-the-clock online assistance. Whether you need help with installation, connection issues, or account management, you can get instant, professional help via online chat or email, with an average response time of fewer than 2 minutes. |
In-Depth Analysis of Protocol Technology
Discover how the cutting-edge routing protocol used by Comet Accelerator delivers unparalleled speed and security.
| Feature | Details |
|---|---|
| WireGuard Core Architecture | Comet Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves full accelerator functionality with just around 4000 lines of code, whereas traditional IPsec requires over 600,000 lines. The streamlined code means a smaller attack surface, lower latency, and higher throughput. In our internal tests, WireGuard's handshake speed is 3 times faster than IKEv2 and 8 times faster than IPsec. |
| Noise Protocol Framework Encryption | Comet Accelerator's implementation of WireGuard uses the Noise protocol framework for key exchange, employing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been extensively validated in academia and industry, providing forward-looking security against quantum computing attacks. |
| Smart Protocol Switching | In certain network environments, the UDP traffic of WireGuard may be restricted. Comet Accelerator features a smart protocol switching function that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring stable connections in any environment. The entire switching process occurs within 500 milliseconds, virtually unnoticeable by the user. |
| Multi-hop and split routing | Comet Accelerator supports multi-hop connections, allowing data to be relayed through two or more acceleration servers for users who require extreme anonymity. Meanwhile, the split routing feature allows you to choose which applications connect via the accelerator and which access the local network directly, achieving the best balance of performance and security. |
Encryption and Privacy Protection
Multi-layer encryption technology and strict privacy policies comprehensively protect your digital life.
| Feature | Details |
|---|---|
| AES-256-GCM Encryption Standard | Comet Accelerator uses the AES-256-GCM encryption mode to secure all transmitted data. AES-256 is the encryption standard endorsed by the NSA for protecting ‘top secret’ information. Even using the most powerful supercomputers, brute-forcing this encryption could take billions of years. A unique session key is generated for each connection, ensuring forward secrecy. |
| DNS Leak Protection | Comet Accelerator operates its own private DNS server cluster, ensuring all DNS queries are resolved through encrypted connections, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection to ensure your real IP address is never exposed. You can verify your protection status at any time with our built-in leak testing tool. |
| Kill Switch | Comet Accelerator’s network lock feature (Kill Switch) can instantly terminate all internet traffic if the acceleration connection drops unexpectedly, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode protects only specified applications, giving users maximum flexibility. |
| RAM-only Pure Memory Servers | Comet Accelerator's 3000+ servers operate in pure RAM mode. This means there are no hard drives on the servers, and all data is processed only in memory. Every time servers reboot, all data is completely wiped. Even if servers are physically seized, no user data can be extracted. This represents 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.
| Feature | Details |
|---|---|
| 4K Ultra HD Streaming Support | Comet Accelerator's high-speed nodes are specially optimized to consistently support the demands of 4K Ultra HD (2160p) video streaming. Whether watching high-definition movies, live sports events, or music videos, Comet Accelerator can provide a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently remain above 500Mbps. |
| Gaming Acceleration and Low Latency | Comet Accelerator is specially optimized for online gaming. Our smart routing engine automatically selects the lowest latency route to gaming servers. In our tests, latency to Asia-Pacific gaming servers is as low as 10ms, and as low as 60ms for North American servers. DDoS protection prevents you from suffering malicious attacks during gaming sessions. |
| P2P and Torrent Download Optimization | Comet Accelerator has enabled P2P optimization on nodes across 30+ countries. We do not limit the bandwidth or speed of P2P protocols like BitTorrent, while protecting your download activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency and supports faster upload speeds. |
| Smart Content Acceleration Technology | Comet Accelerator's proprietary 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, switches to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes when browsing websites. The entire process is fully automated, requiring no manual intervention. |
