Email Security

Email is well-established as the prime means of communication for business purposes, it adds speed and convenience to your day-to-day dealings, but it also is your primary source of risk.

There are many levels of attack that could lead to a compromise of your IT network and ATG have considerable experience of protecting thousands of users from email threats on a daily basis.

Eliminating spam and email based viruses

Email based viruses are a major security threat that cannot be ignored. The effects of these attacks vary from annoying to destructive, but all can have an impact on your business.

Spam emails are an irritating problem that is getting increasingly sophisticated. They can threaten your IT system security by providing links to web sites that can be offensive to your employees and may include viruses, phishing scams, trojans and worms. Spam also uses up network bandwidth, slowing down your email server and wasting time for employees.

There is also a risk that with an incorrectly configured email server, spammers can use your business email server to send unsolicited emails. This could potentially lead to your server being added to a 'real-time' black hole list, which in turn could lead to ISP's rejecting email sent from your business.
