With CrossClave, YOUR data comes first. For us, that means providing a solution you can trust.

That means 100% complete security and privacy. Opaque isn’t good enough – even our staff won’t see your data, so you can rest assured what you share with your inner circle or your team is between you and yours. We utilize the top security and tech possible to encrypt your files across chat, file sharing, and video.

  • A place to share
  • Store, share and collaborate on anything you want.
  • Chat, voice and video freely with no limits.

Try it for yourself

Ad-Free, Tracker-Free Secure Sharing

We mean it. Trust means no one monitors your data but you. Did you know many popular file storage and sharing programs actually give their employees or third parties the ability to check out or monitor your data? With CrossClave, no one sees your data except for you because we encrypt everything before it leaves your device.

Do you want a stranger looking at your personal photos and important work documents? Neither do we! This is why we made CrossClave – we believe privacy and security should be a fundamental part of online interaction and collaboration.

Free Chat and Video Calling

No hidden fees, no fine print – just 100% clear, reliable, global communication, 1-on-1 or in a group.

Your Data is Safe

You won’t find any annoying quizzes asking what kind of lawnmower you are – there’s no sourcing or tracking of your data. We don’t intrude – we simply give you a secure, reliable space to share.

Feature-rich chat in every space. Only those in the space have access to chat or file data.

Crossclave Puts Secure Collaboration First

Security is not an add-on.

Add team members to spaces. Roles and access controls can be determined by policy or adjusted manually on an as needed basis.

Most of the commercially available communication and collaboration offerings on the market today are designed exclusively for operational efficiency, i.e., increasing the output and profitability of a dispersed virtual workforce.

For most companies, security only becomes a priority after something happens, and something always happens. When it does, a reactive approach to security is little comfort to users whose sensitive data and private communications have been exposed to the outside world.

CrossClave is built, from the ground up, with security in mind. Because the security is baked-in, not bolted-on, organizations with sensitive, critical information can finally take advantage of remote collaboration and communication efficiencies that can be realized with a productivity suite.

CrossClave’s Security Architecture

Zero-trust and Distributed Ledger

CrossClave leverages zero-knowledge encryption and distributed-ledger capabilities to render entire categories of vulnerabilities obsolete and extend a level of protection to remote work unachievable until today.

End-to-End No Knowledge Encryption

CrossClave encrypts everything using NSA CNSAS cryptography. Keys to ciphers are held only by endpoints with a need to know – never by the server or administrators. True cloud encryption is possible, and CrossClave may be configured to use a specified algorithm, or even interface with hardware-based encryption modules.

Cryptographic Compartments

CrossClave allows all users to create compartments that are cryptographically kept separate from all other compartments within CrossClave, allowing teams to create spaces that precisely reflect their security landscape.

Enforced Need-to-Know

CrossClave’s unique policy engine closes loopholes in authority and permission schemes. Simple coding can produce a series of facts and rules which govern all actions within CrossClave, which will reject all access requests or actions from those without a defined need to know or authority.

Irrefutable Logging

CrossClave is built on a distributed ledger that exactly reflects both the current and past states of the system. These logging capabilities mean that the state of the system can be reviewed, and access to data can be precisely defined for any time within the system’s history, giving nearly unprecedented insights during security reviews.

crossclave consumer data

Commercial Data Classification:

  • Confidential is the highest level of commercial data classification. This is used for data that is extremely sensitive and for internal use only. A significant negative impact could occur for a company if confidential data is disclosed. (Confidential data is company data)
  • Private is used for data that is of a private or personal nature and intended for internal use only. A significant negative impact could occur for the company or individuals if private data is disclosed. (Private data is data related to individuals)
  • Sensitive data labels are used for data that is more classified than public data. A negative impact could occur for the company if sensitive data is disclosed.
  • Public data is the lowest level of classification. This is used for all data that does not fit in one of the higher classifications. Its disclosure does not have a serious negative impact on the organization.
  • Consumer: designed specifically for individual or small groups of users. Privacy focused, ephemeral.
  • Business: designed specifically for enterprise users. Confidentiality focused, persistent.
