Many websites now serve all of their content through encrypted connections. Router Limits does not break these encrypted connections, to protect users' privacy and limit our liability. Breaking encryption would require our servers to be privy to the contents of all users' encrypted connections — that includes banking information, private emails, etc. We don't want to snoop on that stuff!
Google and Bing search engines are also encrypted connections; however, they provide a way for Safe Search to be enforced. Generally, our recommendation for this scenario is to block the "Search Engines" category, enable Safe Search, and then add the "Google" and "Bing" sites as exceptions. Or, you can just click on DEADBOLT in your Limits screen, and that will be automatically configured for you.
When an encrypted connection to a website is blocked by Router Limits you may not see our familiar "Limit in Effect" blocked page. Instead, you may see a security/privacy warning from your web browser (e.g. "connection not private"). Don't worry; that just means "blocked."
You can tell a website is using encryption when you see HTTPS instead of HTTP. The "S" stands for secure and means it is using SSL (Secure Sockets Layer) and TLS (Transport Layer Security)
