Viruses and threats carried in by e-mail happen more frequently and become harder to catch. You need to do everything you can to protect your network. That's why WatchGuard has introduced Gateway AntiVirus for E-mail for your Firebox X.
Gateway AntiVirus for E-mail integrates onto your Firebox X to give you comprehensive protection against e-mail borne threats at the gateway, before they enter your network. To keep you protected as more threats come out, a growing database of over 22, 000 signatures continually updates itself from WatchGuard's Threat Defense System multiple times daily to your Firebox X.
But using signatures to keep you protected is not enough. From the time a virus is in the market until a signature is released, you could still be vulnerable. Firebox X's Intelligent Layered Security architecture provides multi-layered protection through the deep application inspection to keep out e-mails that don't look right, not just what looks wrong. Known as zero day protection, Firebox X defends against the attacks proactively until a signature is available.
The yearly subscription is affordably priced by model, regardless of how many users you protect with your Firebox X. You'll know what's happening through the intuitive management console that shows you how well you are protected, with WatchGuard Gateway AntiVirus for E-mail.

Several DGS-3627 switches may be physically stacked, using low-cost CX4 10 Gigabit copper modules. In this configuration, one or two 10-Gigabit uplinks may be created, depending on whether the linear or fault-tolerant ring stacking1 is implemented. Up to 12 switches can be stacked in this way.
Using the low-cost coaxial cable as the medium to stack switches together provides not only high-bandwidth stacking but also the flexibility to add 10-Gigabit uplinks strictly as needed. The three open slots can also be used for optional 10-Gigabit XFP fiber uplinks to servers or a backbone connection.
With D-Link Single IP Management (SIM) support, you can easily add up to 32 switch units -regardless of the model- in a virtual stack in addition to your physical stack. Multiple switches can be configured, monitored and maintained from any workstation running a Web browser via one single IP address. The stack is managed as a single object, as all stacked units are identified by a single IP address. A simple yet powerful web-based interface allows you to perform most management and configuration tasks.
A complete set of security features is provided, which includes L2/L3/L4 multi-layer Access Control Lists (ACLs) and 802.1X user authentication via TACACS+ and RADIUS servers. The switch also offers suppression capabilities and Layer3 IPv4/v6 static routing to increase network performance and security. In addition, when implemented in conjunction with a D-Link NetDefend firewall, this switch as a stand-alone or in a stack, is able to automatically quarantine any host displaying abnormal behaviour. Finally, D-Link's ZoneDefense, provides proactive network security by preventing viruses from spreading through the network and thwarting harmful network attacks.
The DGS-3627 switch provides VLAN support including GARP/GVRP and 802.1Q to enhance network security and performance. The switch implements a robust set of multi-layer (L2, L3, L4) QoS/CoS features to ensure that critical network services like VoIP, ERP, Intranet and video conference are prioritised. Bandwidth control allows administrators to set traffic limits on each port, ensuring a committed level of service for end users. For advanced applications, per-flow bandwidth control allows easy fine-tuning of service types based on specific IP addresses or protocols. In addition, a unique feature, D-Link Safeguard Engine, allows administrators to configure thresholds that limit the impact of packet flooding typically caused by virus/worm outbreaks. This increases the switch's reliability, serviceability and availability.

Sometimes, for whatever reason, it's just not possible to pay for a product in full, at the time of purchase. That's why a Dabs Credit Account can be so handy. When you purchase with instant credit from Dabs you can be sure of two things: firstly that you're getting a good deal, and secondly that you won't miss out on a great product (such as this Cisco 24-Port VOIP Gateway) just because you can't afford to pay for it in full right away. Take your time ... weeks or even months, the choice is yours; and then, if you want to pay off your account at any time, no problem, you can do that as well.
Not many UK electronics companies offer credit these days, and so when you find a well-known company such as Dabs which offers instant approval credit accounts, with the balance not due for several months, then it's a deal too good to miss. Spreading the cost of your electronics purchase makes a lot of sense for many people, and although you may accrue some interest when using your Dabs instant credit account, since the account is not a zero-interest account, the benefits are obvious, and more than worthwhile. So, the Cisco 24-Port VOIP Gateway can be yours for a lot less than you might imagine, and if you don't want to pay for it right away, then it's no problem.
So, if you're interested in owning the Cisco 24-Port VOIP Gateway, then you can buy it right now and either spread the cost or pay in full when you purchase, using a credit card or debit card. Additionally, once you've shopped at Dabs, then you can also take advantage of other special offers from Dabs Electrical.
