Weekly Threat Pulse (2/15)

Wondering what this weekly list is all about? 

For starters, it's not marketing fluff.

In fact, it's meant to be an informative snapshot of the value a lot of your colleagues are already getting every day with Fletch.

Picture getting a list like this every day that tells you the threats that are going to be a big deal and if those threats impact you at all (Fletch automatically correlates your data with what's going on in the world so you don't have to spend days doing it). 

You'll finally get ahead of those annoying CFO asks.
