Spam Blocker

Around 80% of emails sent globally continue to be spam, with attackers constantly looking for inventive ways to get their messages delivered to unassuming users. As they become more creative in their use of technology to get around anti-spam solutions, it has become even more important for anti-spam solutions to effectively block spam and phishing attacks while maintaining a low false positive rate.
