Window actuator for stair windows

You are only safe if you brick up every window opening and replace them with screens.

I agree with guckuck2 - completely tolerable. Why should a burglar - who doesn't know about the lack of locking - choose one of the most difficult windows to reach from the outside as a target?

But from the outside the window is indeed very easily accessible

So you would definitely commission the window drive, right?

Of course! What would your alternative be? At the beginning of the planning, I might have planned a fixed window if you’re not going to get to it anyway. Otherwise, if your safety is so important to you, leave the window as it is and just don’t open it. You probably won’t open it very often anyway (why would you).
