The correct command is show security utm web-filtering status. This operational mode command verifies whether the web-filtering service connection is up. For NGWF, the SRX sends URL or destination IP information to the Juniper NGWF cloud, where the URL is categorized and reputation information is returned to the device. Because NGWF depends on cloud connectivity, checking web-filtering status is the appropriate troubleshooting and verification step. The anti-spam and anti-virus status commands verify different Content Security services, and content-filtering statistics show content-filter counters rather than cloud web-filtering connectivity. Juniper documentation also notes that this command can confirm whether web filtering is down because of a missing license or service condition.
