SpamTitan is an email filtering solution that provides anti-spam and antivirus protection for businesses. It is designed to detect and block email-borne threats including spam, phishing, malware, ransomware, and Business Email Compromise (BEC) attacks. The solution applies multiple filtering mechanisms beyond conventional email filtering, including greylisting, real-time block lists, Sender Policy Frameworks, and Recipient Verification Protocols. It uses AI-enabled detection to identify emerging and evasive threats such as zero-day malware and polymorphic malware that signature-based tools struggle to detect. SpamTitan claims a spam catch rate of 99.99% and the ability to identify 100% of inbound malware. The product also supports scanning of outbound emails to protect IP reputation and prevent blocklisting. It is positioned as a more capable and cost-effective alternative to built-in email filters such as Microsoft Office 365's Exchange Online Protection (EOP), with advanced features available out-of-the-box rather than requiring additional enterprise licensing. The solution is available as a cloud-based service and is noted for its multi-tenant support, making it suitable for managed service providers serving multiple client organizations.
