The Security Advisor will remove the HTTP Check module from ArcGIS Online login accounts
The October 29th release of the Security Advisor will no longer make the HTTP Check module available to ArcGIS Online login accounts. Customers using ArcGIS Enterprise login will still have the HTTP Check module available until the end of 2021 – when the HTTP Check module will be retired.
The HTTP Check module was provided to help migrate item content in preparation of December of 2020 when ArcGIS Online would be enforcing HTTPS only references.
Remember that the best way to access and use the Security Advisor is from the ArcGIS Trust Center.
