Move terabytes in minutes — without the cloud.

CROSSBOW

CROSSBOW transfers your largest files directly between offices, partners, and continents.
No cloud uploads. No relay servers. Up to 30× faster than FTP, even when networks are unstable.

Why teams switch to CROSSBOW

30× faster than FTP, HTTP, or email. A 500GB project file that took 8 hours now arrives in 20 minutes. Your team works while files move — not the other way around.Files stay between you and your recipient. Direct peer-to-peer transfer. No middleman, no cloud, no copy left behind on someone else's server.Every byte verified. Guaranteed.
Built-in checksum validation means files arrive identical to what you sent — every time, no exceptions.
Pause, resume, prioritize — without losing progress. Switch a transfer to high priority for a deadline. Pause when you need bandwidth. Resume from where you left off, even days later.Saturate your full bandwidth.
Most tools waste 60–80% of your connection. CROSSBOW uses every megabit you're paying for.

No cloud. No servers.
No data leaks.

Most file transfer services route your data through their servers. We don't. CROSSBOW connects your endpoints directly. Your files never touch our infrastructure — or anyone else's. They move from your machine to your recipient's machine, and that's it. This means:- Your IP stays your IP. Source code, designs, financial records, patient data — none of it sits on a third party's storage, even temporarily.- Compliance becomes simple. No vendor data residency questions. No third-party audit trails. The data path is yours alone.- Air-gapped networks supported. Need to move files inside an isolated network with no internet access? CROSSBOW works there too.

Built for the real world — not the lab.

Real networks lose packets. International links have high latency. VPNs add overhead. FTP and HTTP weren't designed for this — they treat every hiccup as congestion and slow down dramatically.
CROSSBOW takes the opposite approach. Our MKUDP engine recovers lost packets without throttling. The result: consistent high-speed transfers, even when:
- You're moving files between Seoul and São Paulo
- You're working over a corporate VPN
- Your ISP is having a bad day
In tests with 1% packet loss on transcontinental links, CROSSBOW maintains throughput where FTP slows to near-zero. Real-world speedups of 50× to 500× are typical for international long-haul transfers.

Encryption that doesn't slow you down.

Most encrypted file transfer tools cut your speed by 30–50%. CROSSBOW keeps you at full throughput.
We use ChaCha20 — the same modern stream cipher trusted by Google, Cloudflare, and WireGuard. It's designed for high-performance environments where AES would create CPU bottlenecks. What this means for you:
- 256-bit symmetric encryption on every transfer, end-to-end
- Per-session key derivation — no static keys, no shared secrets at rest
- No performance penalty — encrypted transfers run at the same speed as unencrypted
- No backdoors, no telemetry, no key escrow — your keys stay on your machines

One license. Unlimited partners. Zero seat fees.

Traditional file transfer software charges per user. Add 50 partners, pay 50 licenses. Add 500 partners, pay 500.
CROSSBOW works differently.
Install the FULL version on your central server — that's your one license. Your partners, vendors, and contractors download our free LITE version and connect directly to your server.
The result: a private 10Gbps transfer network across your entire supply chain — at a flat annual price, regardless of how many partners you onboard.
Best for:
- Studios with rotating freelance teams
- Manufacturers with dozens of suppliers
- Defense primes with subcontractor networks
- Hospitals coordinating with referral clinics
