Frequently Asked Questions

What is a Network Security Gateway?

Network security gateways are the successors of traditional firewalls, unified threat management (UTM) devices, and the latest cycle of "next-generation" firewalls. Traditional firewalls forward packets and block functions often employing packet inspection. UTM devices usually add content security functions. Next-generation firewalls add detection and control of social media and Web 2.0 applications, but typically fail to integrate these functions tightly with link management, WAN management, and SSL VPN remote connectivity.

In comparison, the Barracuda NG Firewall, the first true network security gateway, starts by integrating an advanced network firewall with Layer 7 application recognition and user awareness, content security, malware protection, plus IPS in a suite of security technologies. It tightly integrates these features with intelligent network link aggregation and traffic management, VPN WAN management, and optimization for seamless remote office integration and SSL VPN for remote client security. As a network security gateway, the Barracuda NG Firewall weaves a seamless fabric of security, performance optimization, high-availability, and centralized management into network infrastructures while simplifying network architecture.

 

What are the differences among the Barracuda NG Control Center editions?

The Barracuda NG Control Center is offered at three levels - Standard Edition, Enterprise Edition and Global Edition. All Barracuda NG Control Center levels enable administration of an unlimited number of Barracuda NG Firewall platforms. The Standard Edition allows for a single configuration group. The Enterprise Edition allows for an unlimited number of configuration groups for a single enterprise / tenant or "range." The Global Edition is designed for service providers that service multiple tenants and allows for separate and secluded configuration trees for each “range.”

What application proxies are included?

Barracuda NG Firewalls include application layer proxies for HTTP, HTTPS (optional), FTP, SSH, as well as a generic TCP and SOCKS proxy.

What is Layer 7 Application Control?

Application identification techniques in traditional firewalls typically rely on Layer 3 (destination IP address) or Layer 4 (TCP port / protocol) definitions.

Next-generation firewalls utilizing Layer 7 Application Control can identify and enforce policy on more sophisticated applications that may hide their traffic inside otherwise "safe" port/protocols such as HTTP. Skype and peer-to-peer (P2P) applications are particularly notorious for requiring Layer 7 Application Control for policy enforcement.

The Barracuda NG Firewall integrates Layer 7 Application Control into its core firewall functions, enabling enforcement of policy based on user ID, security policy, location, and time of day. Policy actions can include blocking, allowing, throttling, or even enabling or disabling of specific application features.

What user authentication methods are supported?

The Barracuda NG Firewall can authenticate users and enforce user-aware policy using Active Directory, NTLM, MC CHAP, RADIUS, RSA SecurID, LDAP/LDAPS, TACACS+, built-in local authentication, as well as x.509 certificates.

Does the Barracuda NG Firewall have per-user fees for VPN or SSL VPN client use?

No. The Barracuda NG Firewall models include unlimited licenses to Barracuda NG VPN clients. With the purchase of the Barracuda SSL VPN and NAC option, there is no limit to the number of Barracuda NG Network Access clients or Barracuda NG SSL VPN users.

What does the warranty cover?

There is a one year warranty against manufacturing defects in the USA and Canada.
