Guest User: Security Policies Enforced

In the past few releases, Salesforce implemented various security settings that comprise an overall public site security policy. In Summer ’20, some settings are auto-enabling in your org, which you can opt out of, though we don’t recommend it. Starting with the next release, Winter ’21, the public site security settings are enabled, and you no longer have the option of opting out. Make sure your org enables all the security settings needed, and test out your implementation.
