High-Speed File Transfer
CROSSBOW
CROSSBOW is an advanced file transfer solution engineered for speed and scale — enabling the transmission of massive files over standard Internet connections up to 30 times faster than conventional methods.
Unlock Maximum Transfer Performance with CROSSBOW
Maximize Bandwidth – Fully saturate your available internet connection to eliminate idle time and wasted capacity.Direct Peer-to-Peer – Transfer files directly between endpoints. No intermediary servers, no third-party storage, total privacy.30x Speed Advantage – Overcome TCP bottlenecks to achieve transfer speeds 6 to 30 times faster than FTP or HTTP.Bulletproof Integrity – Advanced checksum validation ensures 100% accuracy. If a file arrives, it arrives perfect.Dynamic Control – Adjust priorities and pause/resume transfers in real-time to keep your most urgent workflows moving.
Zero Cloud.
Zero Servers.
Zero Internet Required.
CROSSBOW is built on a 100% serverless architecture, completely bypassing external clouds and relay servers.Your files never touch or reside on a third-party server, driving data leak risks down to absolute zero.The ultimate differentiator: CROSSBOW doesn't even require a public internet connection to initiate or complete transfers.It operates flawlessly at max line-speed within fully isolated, air-gapped networks and strict private VPNs.This guarantees the ultimate independent infrastructure, perfectly suited for projects requiring the highest-tier security audits like TPN compliance.
Uncompromising Speed, Even on Unstable Networks
Standard FTP (TCP) protocols are designed to panic; they interpret even minor packet loss (0.1%~1%) or high latency as network congestion, drastically throttling speeds to unusable levels.Crossbow is different. Powered by our proprietary MKUDP, MKFFT engine, it bypasses these inherent TCP limitations.Crossbow intelligently recovers lost packets without slowing down, delivering up to 10,000x faster performance than FTP in long-distance international transfers.
Military-Grade Security, Zero Speed Loss.
Most transfer tools slow down by 50% when encrypted. Crossbow stays at 100% speed with ChaCha20.State-of-the-Art Encryption – All files are secured using the ChaCha20 algorithm, a modern encryption standard designed for both speed and strength.512-bit Extended Key Layer – Enhanced with a 512-bit key space configuration, offering protection that is virtually unbreakable—even against future quantum threats.No Performance Penalty – Unlike traditional encryption, ChaCha20 is optimized for high-performance environments, ensuring zero impact on transfer speed.Military-Grade Security – Protect your most sensitive data with advanced cryptography trusted by security experts and tech giants worldwide.
