NetDefend UTM Firewalls provide a complete set of advanced security features to manage, monitor, and maintain a healthy and secure network. Network management features include: Remote Management, Bandwidth Control Policies, URL Blacklists and Whitelists, Access Policies, and SNMP. For network monitoring, these firewalls support e-mail alerts, system logs, consistency checks, and real-time statistics.

NetDefend UTM Firewalls integrate an intrusion detection and prevention system, gateway antivirus, and content filtering for superior Layer 7 content inspection protection. An acceleration engine increases throughput, while the real-time update service keeps the IPS information, antivirus signatures, and URL databases current. Combined, these enhancements help to protect office networks from application exploits, network worms, malicious code attacks, and provide everything a business needs to safely manage employee Internet access.

NetDefend UTM Firewalls offer an integrated VPN Client and Server. This allows remote offices to securely connect to a head office or a trusted partner network. Mobile users working from home or remotely can also safely connect to the office network to access company data and e-mail. NetDefend UTM Firewalls have hardware-based VPN engines to support and manage a large number of VPN configurations. They support IPSec, PPTP, L2TP, and SSL protocols in Client/Server mode and can handle pass-through traffic as well*. Advanced VPN configuration options include: DES/3DES/AES/Twofish/Blowfish/CAST-128 encryption, Manual or IKE/ISAKMP key management, Quick/Main/Aggressive Negotiation modes, and VPN authentication support using either an external RADIUS server or a large user database.

Maintaining an effective defense against the various threats originating from the Internet requires that all three databases used by the NetDefend UTM Firewalls are kept up-to-date. In order to provide a robust defense, D-Link offers optional NetDefend Firewall UTM Service subscriptions which include  updates for each aspect of defense: Intrusion Prevention Systems (IPS), Antivirus and Web Content Filtering (WCF). NetDefend UTM Subscriptions ensure that each of the firewall’s service databases are complete and effective.

The NetDefend UTM Firewalls employ component-based signatures, a unique IPS technology which recognizes and protects against all varieties of known and unknown attacks. This system can address all critical aspects of an attack or potential attack including payload, NOP sled, infection, and exploits. In terms of signature coverage, the IPS database includes attack information and data from a global attack sensor-grid and exploits collected from public sites such as the National Vulnerability Database and Bugtrax. The NetDefend UTM Firewalls constantly create and optimize NetDefend signatures via the D-Link Auto-Signature Sensor System without overloading existing security appliances. These signatures ensure a high ratio of detection accuracy and a low ratio of false positives.

The NetDefend UTM Firewalls examine files of any size, using a stream-based virus scanning technology which eliminates the need to cache incoming files. This zero-cache scanning method not only increases inspection performance but also reduces network bottlenecks. NetDefend UTM firewalls use virus signatures from Kaspersky Labs to provide systems with reliable and accurate antivirus protection, as well as prompt signature updates. Consequently, viruses and malware can be effectively blocked before they reach desktops or mobile devices.

Web Content Filtering helps administrators monitor, manage, and control employee Internet usage. The NetDefend UTM Firewalls implement multiple global index servers with millions of URLs and real-time website data to enhance performance capacity and maximize service availability. These firewalls use granular policies and explicit blacklists and whitelists to control access to certain types of websites for any combination of users, interfaces, and IP networks. The firewall can actively handle Internet content by stripping potential malicious objects, such as Java Applets, JavaScripts/VBScripts, ActiveX objects, and cookies.

The standard NetDefend UTM Subscription provides your firewall with UTM service updates for 12 months starting from the day you activate or extend your service**. The NetDefend UTM Subscription can be renewed regularly to provide your firewalls with the most up-to-date security service available from D-Link.

Multiple WAN ports support traffic load balancing and failover, thus guaranteeing Internet availability and bandwidth.

The ZoneDefense mechanism, operating in conjunction with D-Link xStack switches, automatically quarantines infected workstations and prevents them from flooding the internal network with malicious traffic.

The D-Link Green certified DFL-1660 and DFL-2560(G) are built with an 80 PLUS internal power supply. 80 PLUS certified power supplies offer increased reliability due to greater efficiency, and provide a reduced cost of ownership through longer equipment life. Additionally, 80 PLUS power supplies help prevent pollution by limiting energy consumption, and run at a lower temperature to reduce cooling costs.

The DFL-260E and DFL-860E save energy automatically through cable length and link status detection. By detecting the length of cables connected to a port, the amount of power used for the port can be adjusted, only using as much as is needed. The DFL-260E/860E can also detect if a port is not in use, such as when a connected computer is shut down or if nothing is connected to the port, and can automatically reduce the power used for that port, cutting energy used for it by a substantial amount.

directives. RoHS directives restrict the use of specific hazardous materials during manufacturing, while WEEE implements standards for proper recycling and disposal. Together, these considerations make D-Link Green firewall products the environmentally responsible choice.
