How CrossClave Works

Teams & Spaces

Organize groups to easily share information with only those who need to know. We encrypt it all to keep it private. Even we can’t see what you have in there.

Compatible & Portable

Share, sync, and collaborate with teammates on Windows, Mac, and Android (iOS and Linux available soon).

Security & Simplicity

Nobody has access to chats and files they don’t need to see. And you don’t have to lift a finger to make sure of that.

Teams Work Better When They Mind Their Own Business

You can never stop people from compromising your company’s security—whether it’s intentional or accidental. But you can protect your company from those people by limiting access to information and files to only the people who need it. Here are some examples:


Barry the IT Guy

He’s essential to all of your work… but does he really need access to every file and internal conversation? With CrossClave, you can set boundaries that keep Barry focused on IT.


Kim the Project Manager

Her firm has dozens of clients. Kim and her team collaborate closely on a few accounts. Their files don’t need to accessed by everyone else, and they don’t need to see more than what they share amongst themselves.


Brenda in Customer Support

She has been working from home for over a year, so it wouldn’t hurt to have her collaborate with better-than-industry-grade encryption.
