Not as secure as you think. I began to use brave because it stresses the importance of security and privacy. It's far from that if you use the free version. You can download any vpn and get the same results and not be restricted to one browser. Quite frequently the browser kicks you out of private browsing mode. You might not always notice it. Private "mode" isn't 100% private as I occasionally get warnings from google saying it is not private. I am considering finding another browser because it just kicks you out of private browsing without warning. This issue is becoming more frequent than in the past.
