[QUOTE="Decopi, post: 985105, member: 67091"] Thank you [USER=38787]@valvaris[/USER]. I apologize because I wasn't clear in my previous message. My question was specific about what you call "Client Protection" (I was referring only to firewall as software: Windows Firewall, third-party firewalls etc installed on client/user computers). I know the different types of firewall (that you kindly described in your last post). But again, my question was specifically about firewalls installed as software on client/user computers. Anyway, your final sentence answered my question. In short, in a hypothetical scenario where there is only a firewall (software) as a SECURITY measure on the client/user computer, browsing/webpage protection is almost nil. Firewall (as software installed on the client/user computer) serves only to improve PRIVACY (blocking telemetry), and in best scenario serves for SECURITY only for some apps and programs (blocking "IN/OUT" connections). Browsing/webpages, which is the major source of threats, requires another type of SECURITY measure. For example, if in the firewall (software) the svchost.exe process has the "IN/OUT" enabled for ports 80, 443, 123 and 53 (required for browsers and basic Windows functions), then any (browsing/webpage) malware or malicious script can find a way to use these ports. Firewall (as software installed on the client/user computer) can't monitor Internet traffic that was allowed/enabled for other processes. [/QUOTE]
