Spam Blocker

80% of all email is either spam, phishing or email fraud, causing each of your users to waste an average of 100 hours per year cleaning out their inbox. For even a single user, Spam Filter quickly pays for itself in reclaimed productivity, not to mention reduced frustration and actual financial losses. Arm yourself and fend off the criminals who are clogging your inboxes and wasting your time.

 

NG Firewall sits between the Internet and your mail server and filters and quarantines fraudulent email—spam, phishing and email fraud—preventing it from reaching your users. Its smart analysis delivers a catch rate of 99.5% while minimizing false positives. Spammers constantly adjust their content and tactics to evade spam blockers. Spam Blocker is updated in real-time to keep you one step ahead of spammers. Quarantine is automatic and maintenance-free.
