Where machine learning for cybersecurity works best now

It seems like just about every security vendor touts some kind of AI or machine learning embedded within their products. But do you really need this technology to have an effective defense? The answer lies in looking at modern methods of attack and seeing whether legacy methods of detection can be successful. In all of these modern-day attacks, the legacy methods of detection -- especially those dependent on historical information, such as signature-based detection and heuristics -- simply won't get the job done. The beauty of machine learning for cybersecurity is right there in the name: It's always learning.
