Preventing Threats

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

Organizations deserve an advanced email security solution that will provide protection from even the most hostile networks. They also need this solution to be scalable and affordable. The EnGarde Email Security Gateway 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.

Guardian Digital outperformed competitive products in both cost-effectiveness and ease of management. Our decision was clear.
