Spam Gateway
An anti-spam gateway filter is a software-based virtual appliance that is installed on-site, instead of in the cloud. It is located behind the firewall, an anti-spam gateway filter that normally prevents more than 99% of spam emails from getting to their destinations – improving productivity and mitigating dangers from phishing, malware, and ransomware.
However, it is significant to note not all gateway spam filter solutions are equally as useful. Some have mechanisms that stop most unsought bulk emails from even reaching the spam gateway. Furthermore, they can reduce the demand on network resources, and the number of email threats that evade detection. This type of anti-spam gateway filter can gain a spam detection rate of 99.97%.
