Explore the core features and technology behind Firefly Accelerator

Next-Gen WireGuard Protocol

Firefly Accelerator fully utilizes the WireGuard protocol, with code size reduced to just 1/100 of IPsec, yet delivering 3-5 times the transmission speed. The streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy exceptional speed without worries about privacy breaches.

Audited No-Logs Policy

Firefly Accelerator implements the industry’s strictest no-logs policy—no recording of connection times, visited websites, IP addresses, or any browsing data. This policy has been verified by an independent audit from the renowned security agency Cure53, with the full report publicly available to ensure every promise is substantiated.

Millisecond-Level Smart Connections

Firefly Accelerator's intelligent routing engine monitors global node latency and load in real time, automatically matching you to the optimal route. One-click connection achieves latency as low as 15 ms, so whether it’s video conferencing, online gaming, or 4K streaming, you will experience a smooth and uninterrupted service.

Global Coverage in Over 80 Countries

Firefly Accelerator has deployed over 3000 high-speed servers across more than 80 countries in North America, Europe, Asia Pacific, South America, and the Middle East. Each server operates in pure RAM mode, wiping all data on reboot to eliminate any chance of data retention at the hardware level.

One Account, Up to 6 Devices Online Simultaneously

With a single Firefly Accelerator account, you can simultaneously secure your phone, computer, tablet, smart TV, and router — up to 6 devices connected together, sharing a secure network for the entire family without additional charges. After setting up the router, you can even protect IoT devices that do not support accelerators.

24/7 Professional Support

Firefly Accelerator boasts a bilingual customer support team available 24/7, providing round-the-clock assistance. Whether it’s installation, connection issues, or account management, you can receive instant, expert help via online chat or email, with an average response time of under 2 minutes.

In-Depth Analysis of Protocol Technology

Learn how the cutting-edge routing protocol adopted by Firefly Accelerator delivers unparalleled speed and security.

Core Architecture of WireGuard

Firefly Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard implements full accelerator functionality with only about 4000 lines of code, while traditional IPsec requires over 600,000 lines. The more streamlined code means a smaller attack surface, lower latency, and higher throughput. In our internal testing, the handshake speed of the WireGuard protocol is 3 times faster than IKEv2 and 8 times faster than IPsec.

Noise Protocol Framework Encryption

Firefly Accelerator's implementation of WireGuard utilizes the Noise protocol framework for key exchange, employing Curve25519 for ECDH key negotiation, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives is extensively validated by both academia and industry, providing forward-looking security against quantum computing attacks.

Smart Protocol Switching

In certain network environments, WireGuard's UDP traffic may be limited. Firefly Accelerator features smart protocol switching that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol to maintain stable connections in any environment. The entire switching process is completed within 500 milliseconds, largely unnoticed by users.

Encryption and Privacy Protection

Multi-layer encryption techniques and stringent privacy policies comprehensively protect your digital life.

AES-256-GCM Encryption Standard

Firefly Accelerator employs AES-256-GCM encryption mode for all transmitted data. AES-256 is the encryption standard approved by the NSA for protecting top-secret information. Even with the most powerful supercomputers, it would take billions of years to crack. Each connection generates a unique session key to ensure forward secrecy.

DNS Leak Protection

Firefly 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 provide built-in WebRTC leak protection and IPv6 leak protection to ensure your real IP address is never exposed under any circumstances. You can verify your protection status at any time using the built-in leak testing tools.

Kill Switch

Firefly Accelerator's network lock feature can immediately halt all internet traffic in the event of an unexpected accelerator disconnection, preventing any data from leaking in an unencrypted state. This functionality supports both system-level and application-level modes: system-level mode protects all traffic, while application-level mode only safeguards specified applications, providing users with maximum flexibility.

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

Firefly Accelerator's high-speed nodes are specially optimized to reliably support the transmission demands of 4K Ultra HD (2160p) video streams. Whether it's HD movies, live sports events, or music videos, Firefly Accelerator can deliver a stable, smooth, and buffer-free viewing experience. With gigabit broadband, speeds can consistently maintain over 500 Mbps.

Game Acceleration and Low Latency

Firefly Accelerator has been specially optimized for online gaming. Our smart routing engine automatically selects the line with the lowest latency to game servers. In our tests, the latency to Asia Pacific game servers was as low as 10 ms, and to North American servers 60 ms. The DDoS protection feature prevents you from suffering malicious attacks during gameplay.

P2P and Torrent Download Optimization

Firefly Accelerator has enabled P2P optimization on nodes in over 30 countries globally. We do not impose bandwidth or speed limitations on P2P protocols like BitTorrent while protecting your download activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature enhances seeding efficiency, supporting faster upload speeds.
