Boundless Guest Security is a DNS-based Web Content Filter solution. This means that DNS requests made from your Guest WiFi will get analyzed.
For example, when a user using your WiFi requests a website from their laptop, smartphone or tablet, this request gets redirected to the WebTitan Cloud. Once there, the DNS request gets checked against your predefined policy and sends a response based on whether the site is blocked or not. If the site is blocked, the user will get an informational message.
If it is not, they will get redirected to the requested site.
All this happens instantaneously, so the user does not perceive any latency or speed delay at all. As simple as that.
