Types of Email Security “On Premise” or “In the Cloud”?
Email security comes in two forms “On Premise” or “In the Cloud”. On Premise solutions reside on the organisations network were as In the Cloud solutions are done out on the internet by managed services providers. On Premise solutions generally tend to be more granular than In the Cloud offerings, although the organisation has the overheads of power, updating the system, providing redundancy should an appliance/ server fail and updating the hardware.

Cygnia’s range of email security solution are extremely configurable and can help as part of a wider DLP strategy.
