Deep Packet Inspection of Secure Socket Layer (DPI-SSL) extends SonicWall’s Deep Packet Inspection technology to allow for the inspection of encrypted HTTPS traffic and other SSL-based traffic. The SSL traffic is decrypted transparently, scanned for threats and then re-encrypted and sent along to its destination if no threats or vulnerabilities are found.
DPI-SSL provides additional security, application control, and data leakage prevention for analyzing encrypted HTTPS and other SSL-based traffic. DPI-SSL supports:
The following security services and features are capable of utilizing DPI-SSL:
DPI-SSL has two main deployment scenarios:
The DPI-SSL feature is available in SonicOS Enhanced 5.6. The following table shows which platforms support DPI-SSL and the maximum number of concurrent connections on which the appliance can perform DPI-SSL inspection.
