Next-Generation Firewall (NGFW)
Cyber attacks are becoming increasingly complex and sophisticated, with more than 90% of security incidents originating from network exploits that are undetected by traditional firewalls. Non-adaptive security perimeters make application-based attacks, zero-day exploits, and AI-based threats increasingly difficult to prevent.
Next-Generation Firewall (NGFW) gives multi-layer protection with application-based inspection, real-time threat prevention, and Zero Trust Network Security to secure networks from modern threats.
Without a NGFW solution, organizations face the following challenges:
Lack of Visibility & Control
Traditional firewalls only recognize port & IP-based traffic without understanding applications and users.
Zero-Day Threats & Fileless Malware
AI-based attacks and fileless malware often go undetected by legacy security systems.
Inability to Implement Zero Trust
Traditional network perimeters cannot differentiate legitimate or at-risk users, devices, and applications.
Key Features & Capabilities
Next-Generation Firewall (NGFW) offers advanced threat prevention and application control features.
Show Details
a. AI-Driven Threat Prevention & Behavioral Analysis
- Deep Packet Inspection & Advanced Threat Protection: Inspect network traffic in real-time to detect zero-day attacks.
- Machine Learning-Based Anomaly Detection: Using AI to identify abnormal network activity before it can be exploited.
- Encrypted Traffic Inspection & SSL Decryption: Analyze encrypted traffic without sacrificing performance or privacy.
b. Zero Trust Network Security & Adaptive Policy Enforcement
- User & Device Identification: Implement policies based on user & device identity, not just IP or port.
- Application Aware Firewalling: Control access based on application, not just protocol or port, to prevent application-based exploits.
- Cloud & IoT Security: Monitor and secure traffic from IoT devices & cloud services.
c. Seamless Integration & Automated Security Operations
- SIEM, SOAR & XDR Integration: Connect with other security systems for faster incident response.
- Automated Incident Response & Policy Enforcement: Automatically apply security policies based on threat levels.
- Security Subscription Services: Supports additional protection such as DNS Security, Anti-Bot, Threat Intelligence Feeds, and Advanced Malware Protection.

How It Works
How NGFW and Threat Detection Work to Protect Against Attacks and Intrusions:
Show Details
a. Traffic Inspection & Threat Detection
- NGFW analyzes all network traffic in real-time, including encrypted traffic.
- Uses Deep Packet Inspection (DPI) to detect attack patterns, command & control (C2) traffic, and zero-day exploits.
- Integrates Threat Intelligence feeds to recognize emerging threats.
b. Application & User-Aware Policy Enforcement
- NGFW restricts access based on user identity, location, and device, not just IP addresses.
- Detects & controls applications running on the network to prevent shadow IT usage.
- Automatically isolates malicious traffic to prevent malware spread within the network.
c. SSL/TLS Decryption & Malicious Traffic Filtering
- Analyzes encrypted HTTPS traffic without compromising user privacy to detect hidden threats.
- Prevents phishing and web-based malware attacks through traffic inspection of cloud & SaaS applications.
d. Automated Response & Security Event Correlation
- If a threat is detected, NGFW can automatically quarantine malicious traffic sources or sever connections.
- Integrates with SIEM & SOAR to speed up incident analysis & response.
- Automatically generates threat reports & compliance audit logs.
