You’ve built a great fortress to keep the outside world outside. Firewalls and email gateways are fortified with anti-virus capabilities. Every network server and personal computer powers up with regularly updated av software.

Since your PCs are protected by border security and anti-virus, do they still need personal firewalls? Some antivirus fanatics think av alone is good enough.

The rest of the world understands that the last chance to protect your network from all threats, both internal and external, is at the enduser level. Anti-virus software can’t stop hackers. Firewalls can.

Many endusers object to anti-spam, anti-virus and content filtering for e-mail at the PC level. Such local filtering processes can slow other processes to a crawl. The result: Filters are often quietly turned off, leaving no protection at all.

Behind the border firewalls: Email gateways, servers and PCs require integral firewalls, along with anti-virus protection that detects both known and unknown viruses. Email gateways must also filter spam and other dangerous or objectionable contents.

With an email appliance filtering messages, PCs can divert the newly-freed power for firewalling.
