About SpamTitan
SpamTitan is a business email filtering product from TitanHQ, an Irish security company. It scans incoming mail for spam, phishing, malware and malicious links before delivery, using Bayesian learning, heuristics, two antivirus engines and sandboxing for suspicious attachments. It is offered as a cloud service and as a gateway appliance you run yourself, and it can sit in front of Microsoft 365 as an extra layer on top of the built-in filtering. Users get quarantine reports to release blocked mail, and admins set policies and block lists per user, domain or group. It is sold mainly to managed service providers and internal IT teams, with pricing by quote and a free trial. As a closed commercial product, it costs more than running an open-source filter, but you don't have to maintain the filtering engine yourself.
Best for: IT teams and MSPs who want managed spam and phishing filtering in front of Microsoft 365 or a mail server.
