Opponent Icon - Blue Shield With Eye

What does this indicate?

Hi,

I have the same question, does anyone knows the answer ?

Those characters are guarding something. They are not hostile but can turn hostile if you come too close or don't leave soon. I believe it's also more difficult to sneak up on them but I'm not 100% sure.

Thanks for your reply !  Sometimes they don't attack me, even though I go close enough to talk to them. Maybe a bug?

[Boeroer]

I believe this can happen after save & reload in that area.
