How to block Zenmate with Mikrotik

i blocked zanmate on mikrotik routeros using layer7 regexp filter

  for regexp syntax

^.+(api.zenguard.biz|zenmate.io|zenguard.zendesk.com|zendesk.com|zenguard.org).*$

first  create a layer7 protocol

Create a Firewall rule

add layer7 protocol in filter role  e.g denied (in my case filter name is denied)

Select action = reject     (or you can simply select drop)

select log if you want to see real time requests

rejectwith = icmp network unreacable or admin prohibted 

click ok to save the on top of everything.

now clock log to view real time zenmate drop requests
