It absolutely is, but if all ads provided value like this and inserted their sell at the end... I wouldn't mind at all. Though maybe adding a disclaimer saying 'in case you didn't check the domain... we're Panther and this is what we do' or so might be more encouraging.
We will definitely add a disclaimer like this in the future! Thanks for the feedback. We really wanted to highlight these security tools that have added so much value to us in the past as practitioners.
