The DFL-860E is an UTM (Unified Threat Management) firewall in the D-Link's NetDefend series. The DFL-860E integrates advanced features to protect a SMB network from Internet threats and internal attacks, while ensuring a smooth operation and improved employee's productivity thanks to its bandwidth management and web content filtering.
The DFL-860E NetDefend UTM Firewall provides complete advanced security features to manage, monitor, and maintain a healthy and secure network. Unified Threat Management 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 the office network 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 remote locations 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.
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.
The NetDefend UTM Firewalls employ component-based signatures, a unique IPS technology which recognizes and protects against all varieties of known and unknown attacks. 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. Consequentially, viruses and malware can be effectively blocked before they reach the 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 black/white lists to control access to certain types of websites for any combination of users, interfaces and IP networks.
