Features

Application Visibility and Control

The Barracuda NextGen Firewall X-Series analyzes network traffic up to Layer-7, leveraging advanced fingerprints to identify applications and content traffic. Based on the fingerprints, a flexible set of actions, including allowing, blocking, resetting, and redirecting connection attempts and traffic can be defined. A library of hundreds of applications is currently fingerprinted. Furthermore, granular policies can be set for specific application features (e.g., limiting audio calls on Skype). These fingerprints are dynamically updated so that security policies and signatures remain up-to-date.

TINA VPN

Due to the limitations that come with standard IPsec connections, Barracuda Networks has created several powerful extensions to standard IPsec tunnel management. This core of the Barracuda X-Series VPN engine is called TINA (Transport Independent Network Architecture). The TINA protocol allows the use of TCP, UDP, and ESP for high speed VPN connections, which improves the VPN connectivity substantially by adding:

  • Endpoint-to-Endpoint (not network-to-network) connectivity
  • NAT friendliness
  • Multiple physical transport paths for a logical tunnel
  • Multiple tunnels between two locations
  • HTTPS and SOCKS4/5 proxy compatibility
  • Dynamic Address Support
  • Tunnel heartbeat monitoring

CudaLaunch

CudaLaunch is an application for Windows, macOS, iOS, and Android devices that provides mobile workers secure remote access to their organization’s private cloud applications and other sensitive information through the Barracuda NextGen Firewall X-Series. CudaLaunch provides several benefits over traditional browser-based SSL VPN remote access. As an app, it provides a familiar app store setup and install experience for end users.

Unlike browser-based remote access, CudaLaunch provides a more responsive look and feel that is unified across mobile platforms and avoids the idiosyncrasies of mobile browsers. Once an end user has started the app, a swipeable Launchpad provides quick and easy access to internal applications, favorites, and full TINA VPN connections (which securely connect the device to your corporate network). These richer VPN connections support mobile apps that connect back to the corporate network, such as remote desktop apps.

Designed to be completely self-configuring, CudaLaunch includes easy central management for large deployments and integrates with the powerful security features of the X-Series firewall. For IT administrators, the X-Series firewall provides one place to manage security policies for all types of remote access (CudaLaunch, SSL VPN, Barracuda Network Access Client, and standard IPsec). The end user experience is consistent across platforms and remote access types, making for ease of use and significantly lower support costs. The self-configuration and management of VPN connections makes setup super easy for end users and removes the headache of supporting the manual configuration of IPsec connections on iOS and Android.
