You keep talking about "Zero Trust" - what does that mean?

SpiderOak solutions are based on a Zero-Trust architecture where, by default, nobody is trusted either inside or outside of the infrastructure – eliminating inside threats, permission creep, and unintentional exposure.

What does blockchain have to do with CrossClave?

Our use of blockchain provides complete attribution and non-repudiation of all data transactions. Every modification made to the ledger is time stamped and signed, digitally ensuring traceability and complete integrity.

How does SpiderOak use this technology for secure collaboration?

The combination of Zero-Trust No Knowledge Encryption and Distributed Ledger allows clients to share data in a secure that even our staff can’t access.

Who is CrossClave for?

We see many businesses use CrossClave, but our app is for anyone who wants to share securely.

What does space have to do with it?

Our technology is used in space – check out our OrbitSecure and Mission Systems offerings to find out more.
