Dealing with spam can be frustrating, expensive and time-consuming. For businesses, spam can be seriously harmful, with attackers using spam email to spread malware to business users. For these reasons, it’s vital that any business relying on emails for both internal and external communications has a strong email filtering solution in place to stop spam.
Email filtering solutions categorize all inbound email traffic to determine whether each email is safe and should be delivered, or malicious and should be blocked. Email filters sort emails into categories like spam, grey-mail, viruses and phishing attacks, which determines whether the emails should be delivered to users.
But not all email spam filters offer the same functionality. Some are simplified for email accounts that need to block spam but don’t need the highest level of threat protection, while others are for enterprise users that need strong defenses against cyber-attacks to protect their users and data.
The anti-spam filters we’ve outlined in this article are all cloud-based solutions. This article will cover the best anti-spam email filtering solutions for a range of use cases.
