DCFW-1800 Series Next Generation Firewall

The DCN Next Generation Firewall (NGFW) provides comprehensive and granular visibility and control of applications. It can identify and prevent potential threats associated with high-risk applications while providing policy-based control over applications, users, and user-groups. Policies can be defined that guarantee bandwidth to mission-critical applications while restricting or blocking unauthorized or malicious applications. The DCN NGFW incorporates comprehensive network security and advanced firewall features, provides superior performance, excellent energy efficiency, and comprehensive threat prevention capability.

Key Features and Highlights

Granular Application Identification and Control

The DCFW-1800E NGFW provides fine-grained control of web applications regardless of port, protocol, or evasive action. It can identify and prevent potential threats associated with high-risk applications while providing policy-based control over applications, users, and user-groups. Security Policies can be defined that guarantee bandwidth to mission-critical applications while restricting or blocking unauthorized or malicious applications.

Control Comprehensive Threat Detection and Prevention

The DCFW-1800E NGFW provides real-time protection for applications from network attacks including viruses, spyware, worms, botnets, ARP spoofing, DoS/DDoS, Trojans, buffer overflows, and SQL injections. It incorporates a unified threat detection engine that shares packet details with multiple security engines (AD, IPS, URL filtering, Anti-Virus, etc.), which significantly enhances the protection efficiency and reduces network latency.
