Subjective reputation is a staple of our industry. Lists of “good” or “bad” indicators are the fuel behind many defensive strategies.

The more advanced tools such as machine-learning, deep-learning, and artificial intelligence are often leveraged to add or remove indicators from these reputation lists.

This discussion will look at subjective reputation, the challenging environments where it is created, and look at alternate approaches worth considering.
