1. Even with the option to warn when using unsecure connection, - notice only happens once in a while.
2. The icon for SecureLine only shows occasionally. You need to check the actual tool to make sure its actually working. 
3. no warning when SecureLine stops working which leaves you unprotected.
It's worse when you expect protection and then find out that protection isn't working.
Need some fixing please. 
I experienced the same issues when first using Secureline and posted with no answers, so I started monitoring the way in which my Computer was connecting to Networks, Secured or Unsecured.
If the connection setting is to connect "automatically" then there seemed to be inconsistent response from Secureline in Icon appearing and warning.
HOWEVER, if the connection setting is not set on automatic and you preview available networks and "manually" connect to the one you want then I found Secureling responded properly everytime.
Not sure why only it worked for me
Edit: You probably may be aware of this, but I should mention Bob, in my use, Secureline often does not appear until a Browser is opened and the "Terms and Agreement" is accepted presented by Public Network( Unsecured) For example Second Cup or Tim Hortons etc.
Once I click on Accept then Secureline Icon appears with the Unsecured Network pop up to connect> Yes or No
