Powerful VPN Engine
Hardware-based data encryption and authentication for IPSec, PPTP, and L2TP in Client/Server mode enable fast and safe handling of VPN traffic.

Professional Intrusion Prevention System (IPS)
Automatic updates from a comprehensive IPS signature database focus on attack payloads to protect the network against zero-day attacks.

Real-Time Antivirus Inspection (AV)
The antivirus engine scans using the most complete, most up-to-date antivirus signature database. Streaming-based pattern matching provides the effective protection against viruses.

Fast, Efficient Web Content Filtering
Multiple index server implementation, highly granular policies, black lists and active content handling enhance performance and effectiveness of web surfing control.

Acceleration Engine for Unified Threat Management
A powerful processor allows the firewall to carry out IPS and Antivirus scanning simultaneously without performance degradation.

Licensed for Unlimited Users
Optional subscription services for IPS, Antivirus Scanning, and Web Content Filtering are priced per firewall rather than per user, thus reducing the total cost of ownership for licensing.

WAN Link Load-Balancing and Fault-Tolerance
Multiple WAN ports support traffic load balancing and failover, thus guaranteeing Internet availability and bandwidth.
D-Link End-to-End Security (E2ES) Solution*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. 
*For DFL-860, DFL-1660, and DFL-2560(G) only

D-Link Green Certified
The DFL-1660 and DFL-2560(G) have attained D-Link Green Certification. These firewalls are built with an 80 PLU S internal power supply. 80 PLU S 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 to prevent pollution by limiting energy consumption, and run at a lower temperature to reduce cooling costs.

D-Link Green certified devices comply with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) 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.

Today’s continuously shifting security environment presents a challenge for small/home office networks with limited IT capabilities. Fortunately, the D-Link NetDefend Unified Threat Management (UT M) firewalls provide a powerful security solution to protect business networks from a wide variety of threats. UT M Firewalls offer a comprehensive defense against virus attacks, unauthorized intrusions, and harmful content, successfully enhancing fundamental capabilities for managing, monitoring, and maintaining a healthy network.
Enterprise-Class Firewall SecurityNetDefend UT M Firewalls provide complete advanced security features to manage, monitor, and maintain a healthy and secure network. Network management features include: Remote Management, Bandwidth Control Policies, URL Black/White Lists, Access Policies and SNMP. For network monitoring, these firewalls support e-mail alerts, system logs, consistency checks and real-time statistics.
Unified Threat ManagementNetDefend 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 realtime update service keeps the IPS information, antivirus signatures, and URL databases current. Combined, these enhancements help to protect the office network from application exploits, network worms, malicious code attacks, and provide everything a business needs to safely manage employee Internet access.
Powerful VPN PerformanceNetDefend UT M 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 remote locations can also safely connect to the office network to access company data and e-mail. NetDefend UT M Firewalls have hardware-based VPN engines to support and manage a large number of VPN configurations. They support IPSec, PPTP, and L2TP protocols in Client/Server mode and can handle pass-through traffic as well. Advanced VPN configuration options include: DES/3DES/ AE S/Twofish/Blowfish/CA ST-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.
UTM ServicesMaintaining an effective defense against the various threats originating from the Internet requires that all three databases used by the NetDefend UT M Firewalls are kept up-to-date. In order to provide a robust defense, D-Link offers optional NetDefend Firewall UT M 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.
Robust Intrusion PreventionThe NetDefend UT M 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, NO P 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 UT M 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.
Stream-Based Virus ScanningThe NetDefend UT M 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. Consequentially, viruses and malware can be effectively blocked before they reach the network's desktops or mobile devices.
Web Content FilteringWeb Content Filtering helps administrators monitor, manage, and control employee usage of and access to the Internet. The NetDefend UT M 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 highly granular policies and explicit black/white lists 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.
NetDefend UTM SubscriptionThe standard NetDefend UT M Subscription provides your firewall with UT M service updates for 12 months* starting from the day you activate or extend your service. The NetDefend UT M Subscription can be renewed regularly to provide your firewalls with the most up-to-date security service available from D-Link.
