I have checked and the actual support ticket you appear to be referring to is in fact INC-B13421 (VA Scan remediation - HSTS Missing From HTTPS Server) and our support team are already engaging with you, hence no need to post this question here on the PSC.
@JuvanE06 our support team resolved your ticket INC-B13421.
The question here is whether the request headers are being set by the application server or application ? As per the screen shot of the existing custom response headers configured in the application, we have set the strict-transport-security at application level.
But from the headers before login, we could see the X-Frame-Options, X-Content -Type -Options etc in the headers which are not configured at application level and indicates , these might be configured at application server lever. So, requested you to validate the configurations are application server level.
Issue primary reason description:
Application is no more vulnerable to HSTS as , HSTS is being handled at application level as a part of custom response headers.
Explanation description:
Please refer below doc on how to configure and to know how application is secured using response headers.
