Verizon is joining AT&T and T-Mobile in pushing out the first security update to the Galaxy S7 and Galaxy S7 edge on its network. The carrier only notes bringing the phone up to date with the most recent security patch in its changelog. From Verizon's update page:

The current software update gives you the most up to date Android security patch on your device.

While the Galaxy S7 is still listed as being on Google's February security update (which it launched with), the SE for Android status is now showing a March 10 date.

If you haven't already received the update notification, you can check manually for it. To do so, simply head to your Settings, About device and then check for the update.
