Hosted Service in isolated private cloud

Private cloud

If your security policy or company strategy requires, CryptTalk PRO can also be deployed as an isolated system hosted in a private cloud.

The server environment of our isolated private cloud service is protected and monitored 24/7, guaranteeing the highest availability. We operate several server clusters using reliable, professional data centers in safe locations.

Professional administration interface
and user management

CryptTalk PRO's isolated private cloud solution comes with a comprehensive User Administration Interface, which allows secure-yet-easy user management. Collaboration between organizations can also be centrally administered and managed by defining access and visibility rules and credentials.

All user management procedures can be made compliant even with the strictest internal company policies.

On-site deployment

Implement your own secure CryptTalk PRO system
with full control over all of its components

An on-site deployed CryptTalk PRO service is always maintained by the customer's IT staff, and only they have access to the system's components and its administrative tools. CryptTalk PRO's developers have no access.

Advantages of on-site deployment

Arenim Technologies cannot access any operational information (e.g., list of users, e-mail addresses). The service cannot be remotely monitored or deactivated.

Highly secure

Reachable only internally.
All admin actions are recorded
to an audit log.
Credential management system with multiple admin and user levels.

Full control

Organization, Group and User management. Configuration and update management (forced and recommended settings and updates) with MDM Support.

System customization

Your client application and server backend can be customized to fit your particular needs.
In case of any special demand, please contact us.
