What is key difference between Sangfor NGFW & IAG?

Please any one tell me what is key difference between Sangfor NGFW & IAG?
how these both works?

Dear's,

I am  still not yet cleared with the comments and still in the confisuion.

Whats the NFS Vs IAG and why we use them in the same network......

plz simple elaboration for full image clarification

thanks

Hi

NGFW and SWG’s are often deployed together, as they complement each-others capabilities. NGAF lacks visibility into application and web traffic, causing network blind spots and a widened attack surface. A secure web gateway provides any capabilities necessary to combat and mitigate those risks.

While Sangfor NGAF and IAG have some similar capabilities, there are several distinct differences including:
User Identity and SSL Decryption.
Logging and Reporting.
Application Control.
Proxy Avoidance.

Hi, Sangfor NGFW (Next-Generation Firewall) or the newly solution Sangfor NSF (Network Secure Firewall) are all about advanced threat protection. They combines traditional firewall features with modern tools like deep packet inspection, intrusion prevention systems (IPS), and application control. This helps detect and block cyber threats in real-time, making sure only legitimate traffic gets through.

On the flip side, Sangfor IAG (Internet Access Gateway) focuses on managing and optimizing internet access within an organization. It handles bandwidth management, URL filtering, and user behavior analysis. This helps organizations control how employees use the internet, ensuring efficient and compliant network usage.

In short, while both enhance network security, NGFW is geared towards stopping external threats, and IAG is about optimizing internal network use and managing user behavior
