1. DejaOffice CRM
DejaOffice CRM gives full control to the user. Running on a desktop or self-hosted server, it never sends records to a public cloud. This approach forms a secure self-hosted CRM platform where data rests under your own roof.
The DejaOffice locks every file with AES-256 encryption and uses TLS 1.3 when data travels. Roles and permissions let managers decide who sees what. Audit logs track each change, so regulators can confirm that rules were followed.
