You should have mentioned that you work at Provectus in this article. Feels pretty sneaky to claim to do an impartial review, but provide no negative critique of the one made by your company…
This is indeed a very biased comparision where some features in the comparision table are just claimed to be not supported by other (open source) solutions. Even after reaching out multiple times the article is not updated accordingly. So this has to be considered a sneaky marketing page to be honest.
I might be biased as I'm one of the Kowl authors but I can definetely tell that Lenses is affected negatively the most. Imo it is one of the most complete paid solutions and got the worst marks basically.
