Solution Benefits

Security

Isolation of environments. By not exposing your Corporate Exchange Server to the outside world, you’re dramatically reducing susceptibility to malicious attacks.

Maintenance

As your business and new data protection regulations evolve, it is simple and fast to adhere with those in a centralized place (Gateway).



No direct calls

No “direct” EWS calls from one network to another
