Risks and Implications of Enabling Decryption
Enabling decryption on Palo Alto Networks firewalls provides visibility into encrypted traffic, allowing for threat prevention and policy enforcement. However, it also introduces several considerations:
-
Privacy Concerns:
Decrypting traffic can expose sensitive information. Ensure compliance with local laws and regulations regarding user privacy and data protection.
