Doesn’t this “adaptive system” just become part of the static defense? The same way that a bit of code that checks passwords against a db is “dynamic”, the options are either to beat the dynamic system (guess/phish a password, trick the AI) or find a way around it (use “forgot your password”, find a place that isn’t covered by the endpoint protection feeding the AI). I don’t see how inserting an agent somewhere fundamentally changes anything

It changes how many attempts you get until the attack surfaces changes to react to a failed attack, and it does so in a way that is not predictable to the attacker.
