Usually, inspection settings ALWAYS show as default, UNLESS you really want to protect further against ddos, then you set it to recommended.

Settings...Blades...Threat Prevention...Advanced Settings...General Settings...Fail Mode.&nbsp; This setting still controls the Inspections Settings protections too even though they are part of the Access Control policy now (but didn't used to be).&nbsp;</P> <P>A situation occurred in which the inspection engine could not properly scan the traffic due to it being out of state, and the default behavior is to let it through.&nbsp; Be careful about setting fail-close here since any traffic that cannot be properly scanned will be denied.&nbsp; There are many, many situations that this can apply to that you may not be expecting, such as a password-protected zip file or a file larger than 150MB being encountered with certain types of inspection set.&nbsp; These will start getting denied if you change this setting.</P> <P>This setting is covered in the new <A href="https://training-certifications.checkpoint.com/#/courses/Threat%20Prevention%20Specialist%20R81.20%20(CTPS)" target="_blank" rel="noopener">Check Point Threat Prevention Specialist</A> 2-day course, which was released to ATCs worldwide last month.&nbsp;
