Content Security

  • Support for intelligent web filtering profile selection (SRX300, SRX320, SRX340, SRX345, and SRX380)—Starting in Junos OS Release 23.4R2, dynamic app information from Juniper Networks Deep Packet Inspection (JDPI) is used to retrieve policy information before the final policy match occurs.

    The Content Security profile that is retrieved based on the dynamic app information is more accurate than applying the default profile, which was the earlier approach.

  • Support for cache preload for Enhanced Web Filtering (EWF) (SRX300, SRX320, SRX340, SRX345, and SRX380)—Starting in Junos OS Release 23.4R2, we support preloading of cache with the top-rated, frequently visited URL list along with the classification information at the system startup stage. This feature is useful if your Internet connection is slow and you experience high latency while accessing the Web due to the remote categorization service.

    Because the Web-filter policy decision is based on the URL category information that is preloaded in the cache, you do not experience a lag even when you make the first request.
