Tresorit is aimed at people and teams who will pay for a finished, supported product. It is end-to-end encrypted, runs on every major platform including Linux, and has passed several independent security audits. The company is owned by Swiss Post. The catch is that the clients are closed source and there is no free plan, only a trial. It earns its price if a mature, compliance-ready product means more to you than open code or a low cost.
