Clinked

Clinked has 2 types of users: Members and Guests. You only pay for Members and not Guests. You get 100 members included and unlimited guests for the Starter and Collaboration packages. Guest can use the platform for free. However, they can only access the content that is shared with them (unlike Members) and cannot use some of the collaboration features. Both members and guest could be clients or employees. (more)

All data transfer is encrypted. Clinked uses 256-bit AES, supports TLS 1.2 for all communication. We also monitor the security closely and respond to new vulnerabilities as they are discovered. (more)
