Barracuda Email Security Gateway

Home / Barracuda Email Security Gateway

All of our shared hosting packages (both linux hosting and windows hosting) are secured by the industry-leading protection against spam, viruses and advanced malware—including zero-day ransomware and other threats provided by the Barracuda Email Security Gateway (Barracuda ESG and formerly known as Barracuda Spam Firewall).

Barracuda Comprehensive Protection

Active as a gateway cluster both incoming and outgoing e-mails are filtered with the specific additions and fine-tuning tailored at our customer’s regional and language settings.

Outbound filtering prevents data loss, and optional 96-hour email spooling in the Barracuda Cloud ensures continuity in case of email server downtime.

Comprehensive protection for the long term

The Barracuda Email Security Gateway includes spam and virus blocking, data protection, email continuity, DoS prevention, encryption, and policy management—combined to deliver a complete solution. As new requirements emerge, it is automatically updated with new capabilities to ensure continuous protection.
