PCNSE Decryption and SSL Inspection Practice Question
What is the primary purpose of SSL decryption in a Palo Alto Networks firewall?
⚠ Common exam trap
It's easy for candidates to confuse SSL decryption with performance optimization or privacy features, but the PCNSE exam emphasizes that its core purpose is to enable visibility and inspection of encrypted traffic for threat detection.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Inspect encrypted traffic for malware, exploits, and data leakage.
SSL decryption in a Palo Alto Networks firewall is primarily used to inspect encrypted traffic (HTTPS, SMTPS, etc.) for threats such as malware, exploits, and data leakage. Without decryption, the firewall cannot apply threat prevention, URL filtering, or data filtering policies to the encrypted payload, leaving a blind spot in security enforcement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Mask the original source IP address for privacy.
Why it's wrong here
Not related to decryption.
- ✓
Inspect encrypted traffic for malware, exploits, and data leakage.
Why this is correct
Core function of SSL decryption.
- ✗
Allow only inbound SSL traffic to be inspected.
Why it's wrong here
Decryption works for both directions.
- ✗
Improve network performance by reducing encryption overhead.
Why it's wrong here
Decryption actually adds overhead.
