Let me ask you a few questions before giving you some ideas/hints and indications.

 

The Cisco sizing guideline does unfortunately no longer do a good job in asking all the right questions.

 

They key indicators we would need to know are :

 

a) number of users and domains

b) numbers of inbound and outbound messages per day

In terms of services we would need to know :

 

c) Antivirus yes/no

d) AntiSpam yes/no

e) AMP - Advanced Malware Protection yes/no

f) MAR - Message Auto Remediation yes/no

g) SPF/DKIM/DMARC enforcement yes/no

h) external ThreatFeeds yes/no

i) URL rewrite to proxy yes/no

j) SIEM upload yes/no

k) customer mail rules an filters, how many ?

 

to narrow the platform choices some other questions :

 

l) Is HA High Availability of the email security gateways a requirement ?

m) Do you require hardware appliances or is virtual also an option ?

n) Do you want a hosted service or host inhouse ?

o) What is SLA of the service ?

 

Once I get your answers I will to guide into the right direction.

 

-Marc
