McAfee Inc became the latest company to enter the red-hot and increasingly competitive managed email security space this week, with the launch of Managed Mail Protection, which combines spam and virus filtering in a hosted offering.
The company is targeting small and medium sized businesses. Users direct their MX record for their email domain to McAfee, and email is then delivered via McAfee, where it is scrubbed of unwanted messages before being delivered.
The firm said the offering permits customizes content filters and can provide statistical reports on quarantined email. The spam filtering is based on heuristic detection, white and black lists, Bayesian filtering and integrity analysis, among other filters.
