Barracuda Backup appliances

Barracuda Backup appliances depend on industry-standard server equipment from Supermicro with no extra programming or equipment required. All that you require goes ahead the machine, and you don’t need to pay additional for every server or application you need to secure either. Simply get at least one machines with enough stockpiling and system data transmission to adapt and you’re ready, with a few models to browse.

The least expensive is the unattached 190 (£899 ex. VAT), which is gone for littler organizations and departmental reinforcements. It’s outfitted with a solitary Gigabit Ethernet port in addition to 500GB of usable stockpiling to commonly deal with reinforcements of around 200GB. The rest of the models are all rack-mount units with expanding counts of capacity and RAID insurance as you climb the scale. At the top of the line, repetitive power and 10GbE availability are added to the blend.

The most costly model is the 4U 1090, which includes a 34-plate stockpiling cluster, a 10GbE system interface and hot-swap excess power, and conveys a proposed reinforcement volume of 50TB from a usable inside limit of 102TB. The suggested cost for that little part is £121,349 (ex. VAT).

Regardless of the size contrasts, Barracuda Backup machines all run a similar programming, have similar instruments to hand and work a similar way. They can likewise all be utilized to ensure both physical resources and virtual machines with help for VMware and Hyper-V as standard.

Barracuda NextGen Firewall F180

Barracuda NextGen Firewall F180 Review  Firewalls is pointed immovably at SMBs and situations, for example, branch office organizations. Four new work area models join this huge group of apparatuses and are intended to offer undertaking highlights, for example, propelled movement advancement and cloud application controls.

The F180 on survey can deal with around 75 clients with all security administrations empowered or up to 150 clients if it’s sent only for secure remote access. System alternatives look great as it collaborates six Gigabit Ethernet ports with a basic 8-port switch and includes 802.11n remote administrations.

Barracuda NextGen Firewall F180 Review

Barracuda NG Firewall has endeavored to streamline its different memberships to keep away from any shrouded costs, yet there are still extremely numerous choices to drive through. The F180 equipment costs £1,599 ex VAT. This incorporates the ‘base permit’ which incorporates firewall, hostile to spam, mail portal and essential VPN server capacities. To get refreshes for this however, you’ll require an Energize Update membership. A one-year Energize Update membership costs £299, as does the different Instant Replacement benefit which is basically a next business day substitution guarantee benefit for flawed equipment.

Mail entryway and hostile to spam administrations, which are just accessible on the F180 and bigger models, are incorporated into the base permit. The web security benefit costs another £498 every year and incorporates Barracuda’s web channel and malware insurance.

You likewise get IPSec VPN administrations incorporated into the base permit, however in the event that you need Barracuda’s smooth CudaLaunch SSL VPN gateway then you’ll require a Premium Remote Access membership which costs £169 for one year. There’s additional as Barracuda’s new Advanced Threat Detection (ATD) benefit adds another £299 to the yearly bill.

A lofty expectation to learn and adapt

Barracuda guarantees the NextGen apparatuses are anything but difficult to arrange, yet we tend to disagree. The F180 doesn’t have a web interface. You oversee singular firewalls utilizing Barracuda’s NG Admin convenient customer (which can be keep running off a USB streak drive), while different firewalls can be overseen utilizing the discretionary NG Control Center VM.

Introductory organization is without bother as NG Admin starts up a wizard on first contact with the apparatus. It makes a straightforward extension over the initial two Gigabit Ethernet ports for assessment purposes or sets it up in steering mode for creation conditions.

It get a considerable measure trickier from here on in, essentially because of the mind-boggling scope of security includes on offer. Every adjustment likewise requires the significant setup page to be opened for compose get to. Resulting changes must be spared to the apparatus and afterward enacted.


All things being equal, we were inspired with the dashboard which gives a total review of all administrations and updates, a continuous activity diagram and cautions on real security occasions. The Firewall tab demonstrates permitted and blocked applications and URL classifications and also the most recent dangers. The utilization of gadgets implies the view can be tweaked to suit.

Guidelines for everything

Baracuda NG Firewall rules include sources, goals, administrations in addition to activity strategies. Inside every one, you can empower application controls, URL sifting, SSL capture attempt and ATD. Barracuda gives around 100 URL separating classifications and we made a scope of firewall objects with various arrangements of blocked classifications, implementing them with application rules.

Principles additionally control chosen applications and Barracuda offers predefined rules for several applications, prepared for utilize. Normally, Twitter and Facebook are available with the last giving twelve sections to controlling different long range interpersonal communication exercises. Application tenets can likewise be utilized to enable access to applications amid particular circumstances and apply QoS profiles to throttle or organize their movement.

Barracuda NG Firewall controls allow you to fine tune access to a wide range of business cloud apps

For anti-virus scanning, you can globally enable the Avira or ClamAV scanning engines on all policies. If performance isn’t an issue, you can have them both active.

Wireless traffic will be subjected to all firewall checks and guest users can be redirected to a custom web portal complete with AUP agreement.

Anti-spam setup takes a little longer as we had to create mail gateway and spam filter services first as they aren’t enabled by default. Along with scanning mail and sending it on to an internal mail server, there’s also an option in the mail gateway service to transparently scan POP3 traffic.

Advanced Threat Detection

ATD combats the latest malware threats and zero-day exploits by using Barracuda’s cloud-based sandbox technology to safely execute and analyse files to determine if they’re safe. It’s easy enough to configure as you decide whether files, such as Office docs, PDFs and ZIP archives, are uploaded to the cloud and scanned first or delivered and then scanned.

After testing ATD, we were sufficiently impressed to recommend it highly. It has its own dashboard status widget where we could see files being uploaded for scanning and those being blocked. We could also manually upload files and have them checked.

Barracuda SLC : Backing up and Restoring Your System

Backing up and Restoring Your System

You should back up your system on a regular basis in case you need to restore this information on a replacement Barracuda Email Security Gateway or in the event that your current system data becomes corrupt.

Barracuda SLC protects you by extending traditional security with a multi-faceted approach. Barracuda SLC  offers you the potential to easily returned up statistics anywhere. Barracuda SLC firewalls and web utility firewalls are the enterprise’s first solutions reason-built for securing cloud-linked networks

Updating the Firmware on your Barracuda Email Security Gateway

This should be one of the steps the administrator performs in the initial installation of the Barracuda Email Security Gateway. Use the ADVANCED > Firmware Update page to manually update the firmware version of the system or revert to a previous version. The only time you should revert back to an old firmware version is if you recently downloaded a new version that is causing unexpected problems. In this case, call Barracuda Networks Technical Support before reverting back to a previous firmware version.

Updating the Firmware of Clustered Systems

If a system is part of a cluster, we recommend changing the system’s Mode in the Clustered Systems section of the ADVANCED > Clustering page to Standby before you upgrade its firmware, and then repeat this process on each system in the cluster. Once the firmware on each system has been upgraded, you can then change the mode on each system back to Active.

Changing a clustered system to Standby mode before upgrading prevents a system on a more recent firmware version from trying to synchronize its configuration with a system on an earlier firmware version. If you have the latest firmware version already installed, the Download Now button on the ADVANCED > Firmware Update page is disabled.

Applying a new firmware version results in a temporary loss of service. For this reason, you should apply new firmware versions during non-busy hours. Before upgrading, BE SURE TO TAKE THE Barracuda Email Security Gateway OFFLINE. This will ensure that the inbound mail queue is emptied and all messages are scanned before the upgrade process begins. DO NOT MANUALLY REBOOT YOUR SYSTEM at any time during an upgrade, unless otherwise instructed by Barracuda Networks Technical Support.

The current firmware version shows in the top section of the page, with the latest General Release version of the firmware shown below in the Firmware Download section. To download the latest firmware version, click the Download Now button. The web interface will display download progress. When the firmware download is complete, click the Apply Now button. The Barracuda Email Security Gateway will reboot and you will need to log in again to the web interface.

Updating the Definitions from Energize Updates

This should be one of the steps the administrator performs in the initial installation of the Barracuda Email Security Gateway. The ADVANCED > Energize Updates page allows you to manually update the Virus, Policy, and Security Definitions used on your Barracuda Email Security Gateway or to have them updated automatically. Barracuda Networks recommends that the Automatic Updates option be set to On for all three types of definitions so that your Barracuda Email Security Gateway receives the latest rules as soon as they are made available by Barracuda Networks.

Important: If you are using the Barracuda Exchange Anti-Virus Add-in with your MS Exchange mail server, make SURE to set the Automatic Updates option to On in the Virus Definition Updates section of the ADVANCED > Energize Updates page. This is necessary to ensure that the add-in receives constant updates of virus signatures from the Barracuda Email Security Gateway.

Reloading, Restarting, and Shutting Down the System

The System Management/Shutdown section on the BASIC > Administration page allows you to shut down, restart, and reload system configuration on the Barracuda Email Security Gateway. You can also take the system offline if necessary, which is recommended whenever you do a Firmware Update. A unit in Offline (Maintenance) mode will stop accepting incoming mail until it is put back online.

Shutting down the system powers off the unit. Restarting the system reboots the unit. Reloading the system re-applies the system configuration.

You can also perform a hard reset of the Barracuda Email Security Gateway by pressing the RESET button on the front panel of the system. Caution should be used when pressing the reset button, however, since doing so while the Barracuda Email Security Gateway is in the midst of a configuration update or other task can result in inadvertent corruption of the system.

When you press the Reset button, the following actions occur:

  • Reboots the system
  • Resets the IP address if held down for 5 seconds or more. Do not press and hold the RESET button for longer than a few seconds – doing so changes the IP address of the system. Pushing and holding the RESET button for:
    • 5 seconds changes the IP address to the default of
    • 8 seconds changes the IP address to
    • 12 seconds changes the IP address to

Bayesian Database Reset

If you have Use Bayesian set to Yes on the BASIC > Spam Checking page, read this section. For more information about how Bayesian Analysis works, please see Bayesian Analysis Inbound.

  • For a global Bayesian database, the administrator should periodically (every 6 months or so) clear it out by resetting it from the BASIC > Spam Checking page, then, from the BASIC > Message Log page, marking at least 200 messages as either Spam or Not spam using the buttons on the page. Bayesian filtering will NOT take effect until 200 or more of each spam and not-spam messages are marked as such.
  • If per-user Bayesian is enabled (from the USERS > User Features page), each user should reset their own Bayesian database and follow up with marking 200 or more messages as spam or not spam, either in their quarantine inbox (QUARANTINE > Quarantine Inbox page) or from their regular email client if they have installed either the MS Outlook add-in or Lotus add-in. For more information about mail client add-ins, see Barracuda Outlook Add-In Overview 6 and Above and the USERS > User Features page in the web interface.
