windows 10 professional firewall or defender block specific words
I have windows 10 professional and i want to block specific words in internet. Any web content with those words willl block connection. I do remember some years back such can be firewall do it. I do not see this option. I tried to set up inbound rules but no option that it will do packet inspection and isolate https connection and check the stream has specific word like "abc" and block that tcp/ip connection. Pls how can we do this.

Windows Defender Firewall cannot block page content by keyword. It filters connections by attributes such as program, protocol, port, address, and network profile; it is not an HTTPS inspection proxy. With HTTPS, page content is encrypted between browser and site, so a firewall rule cannot search its text. For a home PC, use Microsoft Family Safety web filters for a child account, recognizing that filtering is category and site based. In an organization, use Microsoft Defender for Endpoint web content filtering, Defender for Cloud Apps, DNS filtering, or a managed secure web gateway. Those products enforce domains or categories and provide auditing. Matching a word inside every page would require TLS inspection, certificate deployment, privacy review, and a supported proxy; Windows Firewall alone cannot do it. Remove the experimental inbound rules, because web browsing is primarily outbound, and define an approved domain or category policy instead of matching arbitrary words.
are their third party apps that can do this. I will buy
