Our Secure Services Gateway Solution

For the last two decades, our company has developed and implemented cutting-edge cyber solutions using our flexible and cost-effective open-source platform.  These efforts have been employed to protect some of the largest companies in the world. Now, we’re using that experience to focus exclusively on secure email gateway protection.

Leveraging the benefits of open source development, contemporary cloud technologies, and decades of combined experience protecting enterprises, Guardian Digital engineers have created EnGarde Cloud Email Security to be a cloud security gateway that's unparalleled by any other in the industry.

Guardian Digital fully manages EnGarde and provides comprehensive support to ensure the most effective protection against the most advanced threats. EnGarde gives you not only exceptional protection from the latest phishing attacks, but also the monitoring and policy development expertise by Guardian Digital engineers of your specific system in real-time. We're helping you every step of the way.

Preventing Threats

The global threat landscape is constantly changing.  High-tech hackers use increasingly sophisticated and coordinated attacks on business systems, including botnets, blended malware threats, and zero-day and other advanced targeted attacks.

Organizations deserve an advanced gateway security system that will provide protection from even the most hostile networks. They also need this solution to be scalable and affordable.

The EnGarde Cloud Email Security is the answer. It provides real-time intelligence, comprehensive protection from known and unknown threats, effective defenses against viruses, and protection against phishing and spoofing attacks. Since open-source software is adaptable by its very nature, the advanced machine-learning technology inherent to EnGarde detects and combats new email spam threats in real time.
