Why is SSL/TLS decryption considered critical for effective NGFW security inspection in modern networks?

The correct answer is C. It enables inspection of encrypted application traffic. The majority of modern internet traffic - including web applications, SaaS platforms, and increasingly malware command-and-control channels - is encrypted using TLS. Without SSL/TLS decryption, an NGFW is essentially blind to the contents of this traffic. It cannot run IPS signat

Explanation

The majority of modern internet traffic - including web applications, SaaS platforms, and increasingly malware command-and-control channels - is encrypted using TLS. Without SSL/TLS decryption, an NGFW is essentially blind to the contents of this traffic. It cannot run IPS signatures against the payload, cannot scan for malware, cannot identify which specific application is inside the encrypted tunnel, and cannot perform URL filtering on encrypted requests. SSL/TLS decryption acts as a prerequisite that makes all other inspection capabilities effective on encrypted traffic. It does not reduce latency (A) - in fact it adds some processing overhead. It does not eliminate the need for IPS (B); IPS still performs signature matching on the decrypted traffic. It does not simplify rule design (D).
