What are the advantages of deploying email security as a web managed service?
Because Postini’s protection begins at the place of origin of spam and viruses – the Internet -Postini is able to catch suspicious email before it reaches a company’s network. In addition, Postini is uniquely able to intercept Directory Harvest Attacks (DHAs) (used to steal or harvest email addresses), which can only be done in the SMTP connection stream at the Internet gateway. Unlike solutions that are deployed at the network gateway or at the workgroup server, we are able to keep networks and servers free of malicious attacks and bandwidth-hogging junk email.
