On-Premise Protection
Fortress Shield leverages spam traps around the world to identify email from known spammers and determine whether domains embedded within emails lead to known spam or malware sites. It also protects against attempts to embed text inside images with the intent of hiding content from traditional spam filters. Threats do not always come from the outside. The firewall also checks for internally tainted email to prevent the spread of viruses that don’t access the email gateway.
Robust Protection
Robust protection against malware is provided by a very wide selection of checks and tests, ranging from simple filename rules to content-based file type detection. It also incorporates one of the most sophisticated phishing detectors available anywhere. A shield for your email infrastructure that is always evolving to protect your business.
Easy to Deploy
Intuitive interfaces and reports that you can understand make your email security easy. Fortress is extremely easy to integrate into your existing mail transport system, requiring no modification of existing sendmail configurations. Fortress Shield is used by large and small companies including ISPs, US Government, and the Military.
Spam Protection
Fortress Shield leverages the Fortress Secure Cloud to identify email from known spammers and determine whether domains embedded in email lead to known spam or malware and ransomware domains. The shield provides protection against attempts to embed text inside images with the intent of hiding content from traditional spam filters.
Threat Protection
Fortress Shield automatically scans email attachments in real-time; suspicious attachments are moved to a jailed environment for observation. In addition, all incidents are reported to the Fortress Secure Cloud for future identification. The shield combines behavioral, heuristic, and jailing techniques to protect against targeted attacks.
Virus Protection
Email infrastructures require advanced virus protection. Destruction and release of information or network outages severely impacts productivity and can lead to large financial loss. Fortress Shield scans email and incoming files by using triple Antivirus and Malware Engines. The shield will also decompress archives for scanning to provide complete protection. Virus definitions are automatically updated from Fortress Secure Cloud and loaded into your scanning engine.
