Email Anti Spam And Virus Protection For Businesses
- There Is Hope
by: John Tourloukis
With anti spam vendors offering low cost licensing, businesses can
now afford advanced email spam and virus protection with a simple
to use interface at a much lower cost. The great thing about technology
is that as it evolves it gets faster, additional features and economical.
Over the past few years the same evolution has taken place with
anti spam technology and services. In large part this can be attributed
to the open source software community plus enterprising companies
enhancing the capabilities of this software and packaging it into
easy to use anti spam appliances.
It is not practical to have anti spam software running on desktops
in a networked business environment. Managing all employee junk
email software at the desktop is not realistic. It can be a nightmare
and costly in terms time and licensing.
Spam appliances sit in front of your email server so that when
email comes in it will first go to the spam appliance and the email
will be scanned for spam as well as viruses. The filter will block
the message if it identified as know spam. If the filter is not
sure if the email is genuine it will quarantine and hold the email
at the filter and it will be stored until the recipient deletes
it, releases it to their email box, or they can white list a trusted
correspondent so that future emails will not be held back. This
will greatly reduce the load on your email server and reduce your
bandwidth needs. We have seen anti spam systems block up to 83%
of incoming messages. This could help extend the life of your email
server and push back the need for upgraded capacity.
Most virus outbreaks occur via email and for little cost an appliance
can block viruses before they reach your network and user’s
inboxes. This provides an extra layer of defense in addition to
your current anti virus solution.
Businesses have two options if they use an appliance based solution
for their spam and virus control. They can purchase and administer
their own filter. This is a good option if you have a large number
of employee mailboxes to protect and the technical staff to administer
the spam appliance. Businesses also have the option to outsource
their spam control as a hosted service. This is a good choice for
smaller companies and if information technology is not your specialty.
If you purchase your own spam filter, a subscription to updates
may also be required. Make sure you get upfront pricing for the
add-ons that you will need. If you have more than 100 email users
and the technical staff to maintain the spam appliance, buying your
own filter may be your best option. Generally the basic model will
work for most organizations. Large organizations with thousands
of users will require a spam filter appliance with increases capacity
and features. Spam appliances are designed to work with all mail
systems but some do have specific enhancements for Exchange server
Microsoft’s popular collaboration software and mail servers
that support LDAP (light weight directory access protocol). Spam
appliances use the LDAP protocol to verify recipients before delivering
messages to your email server, this avoids consuming server resources.
If your business has five to one hundred employees, then an outsourced
anti spam and virus filter service is going to be a good economical
choice for your organization. Fees are based on the number of users
and you only pay for what you use. You will not have hardware to
buy, maintain, and upgrade. The upfront cost is minimal and most
email filtering providers will let you try the service for free
at first. Another added benefit to outsourcing your spam control
is redundancy. It is important that you choose a provider that has
their spam and virus filters collocated at secure internet data
center facilities. Data centers provide redundant network connections
and power, so if your email server or internet connection is down
unexpectedly the spam appliance will hold your email until your
email server becomes available, minus spam and viruses.
Anti spam technology is constantly improving and the costs are
getting lower. With increased productivity and an added layer of
defense against virus attacks, an anti spam appliance or service
is something your business can not afford to be without.
