Installing Barracuda Email Security Gateway and Advanced Threat Protection

After researching the pros and cons of email security application among the best out of the bunch, I came to the conclusion that Barracuda Email Security Gateway was one of the polished ones with a wide range of features that came with. Given the fact that Microsoft Email Security, Fortinet Email Security and a few other similar applications are some of the most common and widely used, I choose Barracuda Email Security Gateway for its low cost, effective services and excellent review from world wide customers. I have review demo from local vendor Dristi Tech and proceed further installation according to demo and guidance.

Configuring Advanced Threat Protection
The Barracuda Web Security Gateway leverages Advanced Threat Protection (ATP) to provide for safe use of online applications and tools without exposure to web-borne ransomware and other threats.
Advanced Threat Protection (ATP) is a subscription-based service that detects and notifies the administrator of advanced malware, zero-day exploits, and targeted attacks that are not detected by the Barracuda Web Security Gateway virus scanning features. The ATP service analyzes files downloaded from the internet in a secured cloud based sandbox environment.

How ATP Works
ATP analyzes attachment files (based on file types you specify on the BASIC > Virus Checking page) in the Barracuda ATP cloud and assigns a risk score. Infected files are sand-boxed and deemed malicious by ATP when the service is enabled. Additionally, when user subscribe to the ATP service, user can view infected traffic on the BASIC > ATP Log page. The log provides the option to manually export a file in CSV format.

How to Get and Use ATP:
  • Subscribe by clicking on Click here to activate on the BASIC > Dashboard page as shown below.


  • After clicking activate button your ATP features will be enable.
