Next-Generation Firewall (NGFW)
Next-Generation Firewall (NGFW) is an advanced, integrated security system that provides enhanced visibility, control, and protection against cyber threats. NGFWs combine the functionalities of traditional firewalls, intrusion prevention systems, and application control in a single unified platform. They incorporate deep packet inspection and advanced threat detection capabilities to identify and block malicious activities in real-time. NGFWs also have the ability to detect and prevent sophisticated attacks, such as targeted threats and advanced persistent threats (APT), using threat intelligence and behavioral analysis. These advanced features help organizations improve their overall security posture and reduce the risk of successful cyberattacks.
Guide: Next-Generation Firewall (NGFW)
Importance: NGFW is not just a traditional firewall, but an advanced version that provides improved detection and prevention capabilities. It plays a crucial role in today's cybersecurity landscape by offering deep-packet inspection, intrusion prevention systems (IPS), secure web filtering, and more.
What it is: An NGFW is an integrated network platform that combines a traditional firewall with other network device filtering functionalities. Its advanced capabilities go beyond merely blocking unwanted traffic. They also include abilities such as detecting and blocking malware and managing applications.
How it works: NGFWs inspect packets deeply at the application level to enforce security policies. By performing complete context-aware analysis of network traffic, they enable efficient detection and prevention of any security threats.
