Overall, your open and click rates have remained pretty consistent during this time. If this was a constant occurrence, then it may be of higher concern for your metrics. However, based on your reporting the last few months, only two emails have had significantly higher click rates. It's possible that the institutions of the segments those two particular emails were sent to are simply going to be utilizing the bot checkers more aggressively since they'd be required to.
The only other suggestion I'd have is to swap your authentication to self-authentication since you have your own domain. Ideally, this would show the security algorithms that emails being sent through us by you are effectively coming directly from you, and avoid triggering the clicks/opens from bots.
Beyond that, there's not much else you can do from your end. Our devs are constantly trying to identify the various programs that utilize this functionality, so they can set our system to ignore the behavior and triggers from these particular programs. If, after setting your account up for self-auth, the click rate spikes start bleeding into your other regular sendouts, then it may be worth calling in. That way our general support or higher level technical team can see if there's any further info that can be gleamed from the content of the emails with you live on the phone, or to see if the domains of the contacts that are seeming to bot-click them show any other particular consistencies we can track.
