Brute Force CAPTCHA response page shown to an end-user has a support id and the last digit is truncated.


The support id presented to an end-user won't be matched to the one shown in the asm logs


- ASM Provisioned - ASM policy attached to a virtual server - ASM Brute Force Protection enabled in the asm policy - ASM Brute Force sends captcha mitigation page when a website is under brute force attack.


There is no workaround at this time.
