Cloud computing is a hot topic at present. For the purpose of email filtering software, we can say that it is Software as a Service (SaaS) cloud application.
Moving to a cloud based system ensures two things. Firstly, IT personnel will spend far less time fighting fires caused by email borne threats. Secondly, the cloud will reduce the costs associated with email maintenance.
What this means for you is:
- No hardware installation(s)
- No software installation(s)
- No changes to your infrastructure, no maintenance
More importantly the standard option on MailShark is a free email filtering service. You will consequently save money by not having to pay a cloud based provider.
