01 / THE PROBLEM

A fast connection.
A slow handoff.

Hundreds of gigabytes. Teams on different continents. A deadline that won't move. Even a fast network can leave your files — and your work — waiting.

Distance slows things down.

High latency and packet loss can severely limit conventional TCP transfers, especially over long-distance connections.

LATENCY & PACKET LOSS

Interruptions cost more time.

A dropped connection shouldn't mean sending a massive file all over again. Repeated retries hold up the next step.

INTERRUPTED WORKFLOWS

Detours add complexity.

Upload to a cloud. Download again. Every extra stop adds waiting, another data location, and potential transfer costs.

EXTRA STEPS & COSTS

02 / THE SOLUTION

From your endpoint.
Straight to theirs.

CROSSBOW is a high-speed file transfer solution that connects offices, partners, and data centers directly. Put the network you already have to work.

LESS BETWEEN. MORE POSSIBLE.

A direct route.
A better workflow.

YOUR ENDPOINT
YOUR PARTNER
DIRECT P2P TRANSFER
01

No cloud staging.Files travel directly between your endpoints, without an intermediate cloud upload.

02

No relay in the data path.Your files don't pass through CROSSBOW's infrastructure on their way to the destination.

03

Works inside isolated networks.Transfer within a closed network, even when internet access isn't available.

03 / BUILT IN-HOUSE

Our technology.
From the transport up.

Two proprietary engines. Developed in-house for massive files, long distances, and challenging networks. Each handles a different part of the journey.

01 — TRANSPORT ENGINEDeveloped in-house

MKUDP

Keep the data moving.

Our reliable, high-speed UDP transport engine recovers packet loss and is designed to sustain data flow across high-latency, long-distance networks.

02 — FILE TRANSFER ENGINEDeveloped in-house

MKFFT

Deliver the complete file.

Built on MKUDP, our file transfer engine manages large-file data movement, verifies received files, and resumes interrupted transfers.

04 / SECURITY AT THE CORE

Move with speed.
Keep control.

Your most important files deserve more than a fast connection. Protection is built into the transfer.

End-to-end ChaCha20 encryption

Protect data in transit with encryption between the sending and receiving endpoints.

Your endpoints. Your data path.

Keep files off third-party cloud storage and transfer directly to the destination you choose.

Integrity verification built in

Verify received files and resume interrupted work without starting the entire transfer over.

05 / REAL IMPACT

Less waiting.
More work moving.

Make file transfer a working part of your workflow. Spend less time managing the handoff and more time on what comes next.

Faster↗

Get to the next step sooner.

Use available bandwidth more effectively to move large files and keep production moving.

Resume↻

Pick up where you left off.

Continue interrupted transfers and verify the result, instead of repeating hours of work.

A few things
before you start.

What's the difference between FULL and LITE?

FULL is the central server edition. LITE is the client edition for partners, vendors, and collaborators. Contact [email protected] for help choosing a setup that fits your workflow.

Can CROSSBOW work without internet access?

Yes. CROSSBOW can operate inside isolated networks without internet access. Contact our team to discuss your network configuration and deployment requirements.

How much faster will my transfers be?

Actual performance depends on bandwidth, latency, packet loss, storage performance, and other conditions. Use the free evaluation to test your own files and endpoints on the routes you use every day.
