Fort Systems Limited (FSL) was founded with the goal of providing the best anti-spam solution at a reasonable cost. Our application is based on both open source and commercial software. This approach enables us to combine the best of existing open-source anti-spam solutions and programming tools with our proprietary malware detection tools to provide you with superior protection against all types of messaging malware.


Prior to founding Fort Systems, each of our founders were working on their own version of anti-spam software. As supporters of open source development, we were all familiar with each other’s work. Together, we felt we could develop stronger, more efficient anti-spam and anti-virus software. In 2002, we decided to band together our talents in programming, network administration, and IT infrastructure to form Fort Systems. It’s been over a decade since founding our company and we are proud of the hard work that has gone into developing what we believe are the most accurate, high performing, efficient, affordable and flexible anti-spam solutions available.


All of us at Fort Systems Ltd are committed to providing our customers with the most easily manageable, accurate anti-spam/anti-virus solutions available.
